The research team utilized tools developed by CogniFit Inc., to develop a research project to explore the benefits of precision cognitive training for the improvement of skills associated with executive functions in adults with different forms of epilepsy.
About The EPICOG Project
The EpiCog project began its scientific actions in December 2020 after a recruitment of interested people through different platforms and social units related to epilepsy and Dravet syndrome, thanks to the main impulse of the ApoyoDravet Association and, especially, of its Executive Director, Luismi Aras.
The initial selection of the sample that would participate in the blind randomized controlled trial began a scientific project led by Jon Andoni Duñabeitia, Director of the Center for Cognitive Science at Nebrija University, in which a research strategy was designed that would allow evaluating the benefits of cognitive training in a period of 4 months.
For this, and thanks to the agreement with the company Impulso Cognitivo S.L., chronometric tests were developed to assess the cognitive abilities associated with executive functions (specifically inhibition, working memory and cognitive flexibility) before and after the proposed interventions.
These psychometric tests were created after a thorough process of analysis of the scientific literature on the most affected cognitive processes in people with epilepsy and were used as pretest and posttest measures.
How was the Research Carried Out?
After completing the initial evaluation tests, the participants began an 8-week period of cognitive intervention through the tools of the company CogniFit Inc., thanks to the commitment acquired through its CEO, Carlos Rodríguez, with the EpiCog research project for the improvement of the cognitive health of people with epilepsy.
Participants had free access to the training platform that CogniFit Inc. expressly designed for this project, thus being able to complete a two-month cycle of cognitive stimulation through different game-like challenges to train the most compromised cognitive abilities in the condition.
Each participant had the opportunity to train 3 or 4 sessions per week through digital devices such as computers, tablets or smartphones.
At the end of the training phase, all the participants who had shown good adherence to the intervention again completed the battery of psychometric tests developed by Impulso Cognitivo S.L. and Nebrija University, thus allowing a general assessment of the improvements obtained, as well as a precise evaluation of the cognitive components on which the greatest impact was observed.
Results of the EPICOG Project
In general terms, the results of the EpiCog project showed a particularly good adherence of the participants to the cognitive stimulation process, and a quantitative improvement in the skills associated with executive functions, especially in components of precision and speed of response.
These results will be presented and discussed in depth at the opening table of the third International Congress on Dravet Syndrome and Refractory Epilepsy that will take place between June 17 and 20, 2021: https://www.epibilbao.com/
We are excited to learn more about the results and potential next steps based on these findings and look forward to continuing to support research into the ways cognitive stimulation training can be used to benefit the scientific and medical communities.

CogniFit is excited to announce a unique partnership with Playwing, a sister company of Ubisoft video game industry gigant.
According to Carlos Rodriguez, CogniFit CEO, this project is “an exciting example of the power of CogniFit’s API, which has enabled Playwing to prototype, produce an MVP (Minimum Viable Product), and begin development on a fully scalable, commercial-grade, white-labeled platform that is introducing a brand-new market segment to CogniFit’s brain training technology—all in a matter of weeks.”
Who is Playwing?
Playwing is a gaming developer and publisher company focused on multiplayer, crossplatform and crossplay games, privately owned by the founders of Ubisoft. Founded in 2017 and leveraging their connections with gaming heavyweight Ubisoft, the founders quickly built a successful portfolio of mobile titles purchasable through a proprietary mobile app store and monetized their offerings through a uniquely modern revenue model known as Direct Carrier Billing, which allows users to acquire games and in-app purchases through their mobile telephone service providers, streamlining the purchasing process and removing unnecessary payment intermediaries.
As the company grew, they began to explore whether the business model which they had created and refined in the mobile games space could also function across other product categories. It wasn’t long before Playwing found success with this strategy, with the release of a sports-focused mobile app portal known as 100% Sports, which allows users to access on-demand video and mobile content about their favorite sports teams, including unique, premium content.
The company has also created a magazine reader app, known as Kiosk, providing further proof of the viability of this business model. Building on the success of these new ventures, Playwing began looking for additional verticals where they could create unique mobile stores to continue to expand their core business model. And this is where CogniFit is playing a unique role in the story of this startup.
About the Playwing Partnership
CogniFit has been a leader in the cognitive stimulation and brain training segment for years, providing users with engaging and impactful brain games and cognitive assessment through our desktop and mobile platforms for consumers and providing a range of professional tools for medical professionals, researchers, and educators.
Playwing has proven to be successful at building engaged communities of gamers, sports fans, and readers, and saw the CogniFit API as a unique opportunity to create a new platform for their users to enjoy.

Having seen how cool the early designs and preproduction versions are looking, I can tell you that this is going to be an exciting project to watch.
While we are all eagerly anticipating the final product later this year, why not take a moment to leave comment below and let us know if you have any questions or comments!
Are you ready to try out our sweetest brain game yet? The developers must have been dreaming of working in a candy factory when they began planning this brain game, designed to give our users a fun and engaging way to train some of the most commonly used cognitive abilities!
We are proud to announce Candy Line Up, a cognitive stimulation game that is so sweet we feel the need to remind you: THIS GAME IS, IN FACT, SUGAR FREE, HAS ZERO CARBS, AND PROBABLY WON’T CAUSE CAVITIES.
About the game
Candy Line Up is a fun and relaxing way to stimulate the brain by organizing different types of candy into their respective packaging. Each tube should have a single type of candy, and you can gain points by filling a tube all the way up.
But just when you think you’ve got the hang of it, the game gets a bit more complex, adding unique modifiers to certain tubes. These modifiers could mean that certain candies can’t be placed inside of certain tubes (no one wants to mix those lemon drops with chocolate raisins, right?). Other modifiers may give you extra points or additional restrictions, making each game unique, and creating a fun challenge as users progress through the levels.
The science behind the game
Candy Line Up is a puzzle game that requires the user to plan their moves strategically while maintaining awareness of the various colors, patterns, and other details of the game in order to make appropriate decisions when executing the strategy.
This exciting puzzle game helps stimulate the cognitive abilities related to Planning and Working Memory. As the game progresses, the introduction of unique constraints and obstacles helps to train the cognitive ability for Updating.
Planning is a fundamental cognitive skill that forms part of our executive functions. Planning can be defined as ability to “think about the future” or mentally anticipate the right way to carry-out a task or reach a specific goal. Planning is the mental process that allows us to choose the necessary actions to reach a goal, decide the right order, assign each task to the proper cognitive resources, and establish a plan of action.
Working Memory, or operative memory, can be defined as the set of processes that allow us to store and manipulate temporary information and carry out complex cognitive tasks like language comprehension, reading, learning, or reasoning. Working memory is a type of short-term memory. Working memory refers to the ability that allows us to retain the elements that we need in our brain while we carry out a certain task.
Updating is the ability to oversee actions and behavior as you carry out a task to ensure that it is being completed according to the plan of action. In other words, updating is what makes it possible to ensure that your behavior is appropriate for a given situation and is adapting to potentially changing circumstances. Updating makes it possible to identify and correct any change from the original plan and is a function that we use countless times over the course of a day.
How to play the game
The concept of the game is fairly straightforward. The player must move candies, one at a time, until the tubes are filled with a single type of candy.
However, things aren’t always as easy as they seem: you may only move a candy onto another candy of the same type and color. You must plan your moves carefully so that you can organize the candies correctly and move on to the next level.
When players begin the game, they will be presented with several options for adjusting the difficulty of the game. Choices include how many jars will be present, and the type of modifiers and obstacles the player must deal with.
These modifiers add layers of complexity that make this game infinitely replayable and engaging. Modifiers include:
Colored Coins: Jars with colored the colored coin icon above them give bonus points for filling them with the candy that matches the color.
Prohibited Candies: Jars that have the prohibited candy icon (shown as a candy with a circle and line through it) are not able to hold the corresponding candy.
Lids or Caps: Some jars will be covered by caps, prohibiting the user from adding any candies to the jar while the cap is present.

“If You are planning for a year, sow rice; if you are planning for a decade, plant trees; if you are planning for a lifetime, educate people”
– Chinese Proverb.
Education is one of the most valuable gifts that a society can give to their children. This was true for the earliest groups of hunter-gatherers passing on the knowledge necessary to survive the harsh environment. It was true for the early civilizations teaching the next generations how to build cities and explore new lands. And it is true today, as we prepare students for a modern, interconnected, digital world that is moving faster than ever before.
And just as the concepts and content that we teach evolve over time to meet the demands of the world we live in, so too must our methods for educating students evolve based on new knowledge and understanding of how the human brain works and how to promote effective learning.
One of the schools that is exploring new methods for educating students for the 21st century is Unidad Educativa CREAR, an Ecuadorean education institution for early-childhood, primary, and secondary students whose vision for education is to “bring together students from diverse backgrounds to help them reach their highest mental, physical, social, and emotional potential based on scientific evidence.”
In order to make their vision a reality, they have developed a unique model for educating their students called Neuro-learning.
What is Neuro-learning?
This modern methodology is designed to promote efficient learning and to help students reach their full potential by integrating modern scientific understanding of how our brains function and how we develop mentally, physical, emotionally, and socially throughout childhood and early adulthood.
By using only those education best practices which are tested and backed by scientific evidence, Neuro-learning helps students to take full advantage of their educational possibilities in an enriching, personalized, and multicultural environment.
How Does Neuro-learning Work in Practice?
The educators who created the Neuro-learning methodology prioritized three main areas of education that would be provide the most value for their students: Personalized attention, a focus on development, and a multicultural environment.
The more that scientists learn about the human brain, the more we understand that no two brains are the same. Each student will have their own unique cognitive strengths, interests, and skills and the Neuro-learning methodology has been designed with this basic principle in mind.
Each student’s development is evaluated, and a personalized plan is created based on current neuroeducation principles. As students progress, periodic measurements allow the educators to adjust and adapt the program to the current needs of the student.
A Focus on Development
While many education methodologies focus on mastery of scholastic content, the Neuro-learning model goes beyond simple memorization and instead utilizes the content as a vehicle for promoting active development of the students’ mental, physical, emotional, and social skills.
In addition to this, the Neuro-learning methodology connects students based on their abilities and interests through High-Performance Programs as part of the normal school schedule. These programs allow students to grow beyond the normal limits of the traditional classroom by exploring their talents, interests, and abilities with more flexibility.
A Multicultural Environment
Living in a globalized, interconnected world means that it is more important than ever to understand and be able to interact with people from different cultures and countries. For students living in countries where English is not the native language, learning English can be a critical component of preparing for success later in life.
Neuro-learning creates an environment that promotes language development by incorporating scientific methods which have been demonstrated to be efficient and make learning a language more natural, simple, and practical.
By utilizing neurolinguistic programs, Neuro-learning helps students to improve their communication skills, not only in English, but also in their native Spanish.
Using CogniFit as a Part of the Neuro-learning Methodology
CogniFit is proud to be one of the newest potential facets of the Neuro-learning methodology, serving as another tool for promoting efficient and effective learning outcomes.
The educators at Unidad Educativa CREAR have begun exploring how to incorporate the cognitive stimulation and assessment solutions of the CogniFit Platform for Schools into the educational framework at their school in an effort to further promote the cognitive development of their students.
The initial trial of CogniFit in the classrooms of CREAR will begin in May of this year, and the school will monitor the students’ progress throughout the school year, including general evaluations in May, September, and January of 2022 (the scholastic calendar in Ecuador, which is in the southern hemisphere, runs from May-January).
We are looking forward to this unique partnership and are excited to follow the students’ progress throughout the year.
The cognitive functions trained by CogniFit’s brain training tools—including Focus, Naming, Short-term Memory, and more—are essential in human development and play a key role in learning and using language.
The more researchers investigate how we acquire and process language, the clearer the relationship between our executive functions and language acquisition becomes.
Based on this growing body of scientific work in this area, scientists in the field see the potential of cognitive stimulation focused on specific executive functions and cognitive abilities for increasing and strengthening the neural networks underlying more general domains such as language skills.
But how can cognitive stimulation activities, such as those offered by CogniFit, improve our ability to learn a language? First, we have to understand the history and science behind cognitive stimulation techniques.
The Growth of Cognitive Stimulation
Cognitive stimulation—which includes techniques and strategies that aim to improve the cognitive functioning of different capacities and cognitive functions such as attention, reasoning, memory, perception, abstraction, or language skills—has been an important area of interest among the scientific community since at least the 1970s when researchers began designing clinical intervention programs focused on the restoration of damaged cognitive functions in cognitive domains such as attention, executive functions, working memory, processing speed, and reasoning.
Over the years, cognitive stimulation has grown as a scientific tool. It has been used in a wide variety of areas, such as learning and education, psychological disorders, brain damage, or neurodegenerative disorders, with users reporting improvements in overall cognition and in specific cognitive domains in both healthy and unhealthy samples.
While early research into the effectiveness of cognitive stimulation interventions was focused mainly on how interventions affected the specific cognitive ability being trained, known as near transfer effects (van Heugten et al., 2016), more recent research has been looking into how cognitive stimulation can benefit more general cognitive domains and skills, known as far transfer effects (Dahlin et al. (2008); Hardy et al. (2015); Au et al. (2015)).
The scientific community is beginning to uncover the benefits and far transfer effects of cognitive stimulation beyond the training’s specific cognitive abilities. As this is happening, they have started exploring new ways to leverage cognitive stimulation tools for more generalized applications such as language acquisition.
Optimizing Cognitive Stimulation Programs to Achieve Far Transfer Effects
Based on this concept of near and far transfer effects, we can see the potential for cognitive stimulation tools, like those developed by CogniFit, in generalized domains such as language. But what does a cognitive stimulation intervention need in order to achieve these far transfer effects?
From what is shown in the scientific literature, there are three aspects of cognitive stimulation programs that may be at the center of achieving the beneficial far transfer effects. These include the validity of intervention activities, the timing of the training, and the adaptation of the training to the individual’s cognitive state at each stage of the intervention.
The validity of the intervention requires not only that the intervention trains the specific cognitive ability but also that it is engaging and motivates the user to adhere to and become invested in the intervention.
The timing of a cognitive stimulation intervention is critical. Cognitive stimulation activities activate specific neural activation patterns in the brain. Frequent, repeated training can help create new synapses and reorganize neural circuits. The more frequently that a user trains a specific cognitive ability, the stronger the neural circuits become.
The final aspect of cognitive stimulation programs may be the most important for achieving the desired far transfer effects. Adapting the level of difficulty of the cognitive stimulation tasks throughout the intervention is key to achieving the highest possible benefit. However, simply increasing the difficulty from one activity to the next may not be adequate for every situation. Natural variations in performance throughout the length of the intervention mean that each session should be scaled to the user. Dynamic adaptation, such as with CogniFit’s patented algorithms, is an “essential requisite to foster not only maximization of the benefits of the training, but also adherence to it.”
Applying New Cognitive Stimulation Technologies to Language Acquisition
New technologies have made it possible to create engaging, interactive, practical, and dynamic cognitive stimulation training tools. In addition. the ability to collect and analyze massive amounts of data allows for the development of powerful algorithms which can create personalized training recommendations with dynamically adjusted difficulty. Taken together, these two massive advances in cognitive stimulation programs mean the potential to produce benefits in more general domains such as language is higher than ever.
As our world becomes more interconnected and we interact more than ever before with people from different countries and cultures in our work, school, and travel, the importance of language learning will continue to increase.
Thankfully, it seems cognitive stimulation programs like CogniFit may make it easier for current and future multilinguals to acquire a new language.
Giant companies such as Google, Facebook, and Amazon are battling for a piece of the action through projects such asYouTube,Twitch, andOculus, while veteran companies likeMicrosoft andSony are investing heavily in maintaining their market share. All the while, young gamers are trying to make a name for themselves as ‘Streamers’ or in the fast-growing world of eSports.
As interest continues to grow, and importantly, as companies continue to invest heavily in the video game industry, players from around the world are beginning to see being a ‘Gamer’ as a viable—andpotentially lucrative—alternative to more traditional choices such as being an athlete or musician.
But just as a dedicated athlete knows they must invest time in the gym as well as the practice field if they want to continue to improve, Young Gamers hoping to reach the top of their abilities must work to strengthen their most important muscle: their brain.
eStragy Aims to Help ‘Gamers’ Reach Their Full Potential

With the hot summer months just around the corner for most of us, this exciting puzzle game is the perfect way to keep your mind off the heat while stimulating spatial perception ability.
About the game
Penguin Explorer is a great way to exercise and challenge your brain while helping the fun little penguin clear the snow while avoiding obstacles.
The aim of the game is to help the penguin remove snow from all of the tiles on the map as quickly as possible by sliding along the ice. But be careful to not run into any obstacles along the way!
As the game progresses, the maps get bigger, more complex, and you have to keep your quick wits if you want to clear the board before time runs out. Try to plan each move as quickly as possible to clear the snow from the whole map.
The science behind the game
This exciting puzzle game is based on popular maze-like puzzles with a long history dating back over 50 years.
CogniFit’s team of designers developed Penguin Explorer as a fun twist on this genre of games and created a game that challenges not only the user’s special perception like typical maze games, but also inhibition and planning cognitive abilities.
Let’s take a look at these important cognitive abilities that Penguin Explorer helps stimulate:
Spatial perception is the ability to be aware of your relationships with the environment around you (exteroceptive processes) and with yourself (interoceptive processes).
Spatial awareness is made up of two processes, the exteroceptive, which creates representations about our space through feelings, and interoceptive processes, which create representations about our body, like its position or orientation. Space is what surrounds us: objects, elements, people, etc. Space also makes up part of our thinking, as it is where we join all of our experiences. In order to get proper information about the characteristics of our surroundings, we use two systems.
Inhibition is one of our most used cognitive functions. It is how the brain corrects behavior. Inhibition is what makes it possible for us to stay quiet when you want to say something, but know that you shouldn’t, it’s what helps you stay quiet and seated when you’re in class, it’s what helps you stay safe when someone merges into your lane without using their blinker, and it’s what helps you study or work, even when you get bored or want to get up.
Inhibition allows you to react to unforeseen or risky situations safely and quickly. Well-developed inhibition or inhibitory control can help improve behavior and make it possible to perform better academically, at work, on the road, and with friends.
Planning is a fundamental cognitive skill that forms part of our executive functions. Planning can be defined as ability to “think about the future” or mentally anticipate the right way to carry-out a task or reach a specific goal. Planning is the mental process that allows us to choose the necessary actions to reach a goal, decide the right order, assign each task to the proper cognitive resources, and establish a plan of action.
How to play the game
Penguin Explorer is a deceptively simple puzzle game. Move the penguin up, down, left, or right along the paths, clearing snow from each tile the penguin crosses.
But even penguins, who live in the ice and snow, have trouble stopping on the ice. Each time you move, the penguin will travel along the ice until they run into a wall, so be careful to not slide the penguin into one of the many obstacles on the board!
Try to clear the board as quickly as possible and collect treasures along the way for bonus points!
Playing games like CogniFit’s Penguin Explorer stimulates a specific neural activation pattern. Repeatedly playing and consistently training this pattern helps neural circuits reorganize and recover weakened or damaged cognitive functions.
Now seems like a perfect time to play this fun and exciting puzzle game—and train some of the most important cognitive abilities at the same time!
CogniFit has been a trusted brain-training tool for over 20 years, helping millions of users strengthen the neural pathways that allow us to use some of our most important cognitive abilities; abilities such as memory, attention, focus, and more.
As CogniFit continues to grow, we are always exploring new ways to leverage our powerful technologies to help people—at home, in the classroom, in the clinician’s office, and beyond.
All of CogniFit’s products—both our selection of engaging brain games and training tasks, as well as our selection of cognitive assessments—have been developed through a collaboration between clinicians, psychologists, cognitive scientists, medical researchers, educators, and software engineers. And it is this foundation in scientific best practices which has allowed us to develop one of our most exciting new offerings: the Cognitive Research Platform.
A powerful Cognitive Research Platform for Scientific Investigation
Based on the same core cognitive training and assessment technology already being used and trusted by clinicians, teachers, and families across the globe, the new Cognitive Research Platform has been developed with the specific needs of research teams undertaking clinical, scientific, experimental studies in the areas of cognitive health and well-being in mind.
The platform offers all of the features that have made our other professional platforms, such as the Platform for Health Professionals and the Platform for Educators, so popular; features such as the ability to quickly and easily manage and track multiple users, create groups to organize interventions, and the ability to communicate with users—redesigned with the specific needs of researchers in mind. In addition to these features common across all of our professional tools, the Cognitive Research Platform also includes unique features designed specifically for researchers, such as the ability to assign participants to experimental and control groups with multiple cognitive training intervention options—participants can be assigned personalized training with algorithmically-adjusted difficulty, non-personalized “placebo” training set to the lowest difficulty each session, providing researchers the ability to study the effects of personalized cognitive training versus generic brain games—as well as easy to use methods for collecting and exporting data for analysis including indexed data related to each variable in the study and reference data for calculating fundamental information such as the Z-score.
Another unique aspect of the research platform is the ability for researchers to design investigations focused on specific brain conditions and pathologies (such as Depression, Parkinson’s, and ADHD) in addition to the general cognitive abilities available in the other professional and consumer platforms (such as Memory, Coordination, and Mental Arithmetic).
The Research Platform Opens Exciting New Doors for CogniFit
Though the Cognitive Research Platform is a relatively new venture for CogniFit, we are already seeing interest and, importantly, adoption of the platform in the research community.
As we continue to build valuable partnerships with research teams across the globe, we are greatly increasing our ability to explore the role that cognitive training—not only for general cognitive abilities, but importantly, for specific brain conditions and pathologies—has in improving our cognitive health and well-being.
Developing this deeper understanding of the real-world impacts of specific cognitive abilities and brain conditions, and the effects that cognitive training can have, will allow us to continue to develop our core technologies, improve the efficacy of our current training and assessment tools, and create the next generation of CogniFit products for new segments of the cognitive health market.
We are fortunate to live in a world where the average person lives longer than ever before, where many of the physical ailments affecting humanity have effective remedies, and where nutritional food is readily available to so many of us.
And though we, as humans, still have plenty of work to do in these areas of physical health, the progress we have already made means that we are now able to focus more attention on the mental-health needs of a global population which is dealing more than ever with the effects of cognitive decline due to aging demographics, increased stress- and attention-related cognitive issues due to an always-on, always-connected culture in both our professional and personal lives, and more.
Our goal at CogniFit is to be a leader in this paradigm shift towards providing support and solutions for the increasingly important mental and cognitive health needs of the global community, and we believe that the Cognitive Research Platform is a key piece of this ongoing journey.
As workers move throughout their career, they learn new skills, obtain valuable experience, and become knowledgeable in the important details of their role and their industry. However, this experience doesn’t come without a trade-off. As these veteran employees grow older, they can lose some of the cognitive flexibility and sharpness they had as younger workers just entering the workforce.
And, though it may seem like building teams with members of the same or similar ages would create more fluent and effective communication and less emotional and cultural conflicts, when businesses can successfully take advantage of the unique value team members from across the age spectrum are able to provide, there is potential for the development of new ideas and innovations as these varied experiences and backgrounds mix.
But how can businesses ensure these diverse teams members come together to form a cohesive unit and that employees are able to bring the most value in their roles throughout their career.
Understanding How Businesses Can Create Successful Age-Diverse Teams
The research team behind The DINNOS Project has taken up this exact question in an attempt to address the challenges businesses face when building groups with ‘age heterogeneous team composition’.
This project, which will be evaluating hundreds of small- and medium-sized businesses across the United Kingdom and Germany will focus on two distinct factors which affect the creation of successful age-diverse teams: How managers build and lead teams, and how the cognitive state of older employees affects the success of the teams.
For the first aspect, the researchers will be looking at the effects of leadership training for managers, and for the second, they will be studying the effect of cognitive training for older employees.
Using CogniFit’s Cognitive Training to Improve Workplace Outcomes?
For any employee to be successful, regardless of age, they need to have the appropriate Cognitive Ability—defined in this study as “a general mental capability involving reasoning, problem-solving, planning, abstract thinking, complex idea comprehension, and learning from experience”—required by the role.
The DINNOS Project has partnered with CogniFit to measure and train the cognitive abilities of older employees in areas such as Memory Processes (e.g., Short-term Memory), Executive Functions (e.g., Inhibition and Attention), Processing Speed (e.g., Response Time), and Logical Reasoning (e.g., Planning).
By understanding how the cognitive state of these employees affects the performance of age-diverse teams—and importantly, the role that cognitive training plays in mitigating the negative effects of the aging brain—the researchers hope to be able to develop systems to help businesses create thriving, successful age-diverse teams.
We look forward to posting a follow-up with some of the important insights the research team learns once the results have been collected and analyzed.
CogniFit has been working hard this year to continue providing our users with the highest quality games and activities. Our newest addition is a fun and challenging mathematical game called Digits.
About the game
Digits is a mathematical puzzle game that tests the user’s ability to quickly organize numbers according to the indicated rules.
While the game starts out simple enough—with only a handful of numbers and a single rule— user’s should keep their focus, because the game can quickly present a challenge for even the sharpest minds. As the game progresses, not only does the quantity of numbers increase, but also the complexity of the rules, and users will have to keep up a fast pace if they want to finish each level before the timer runs out!
While playing Digits, users are stimulating specific neural activation patterns related to these cognitive abilities. Repeating and training these patterns consistently can help create new synapses, and help neural circuits reorganize and regain weakened or damaged cognitive functions.
Let’s take a look at these core cognitive abilities, how they help us with tasks, both simple and complex, in our everyday lives, and what makes them so important to everything we do:
Processing speed is one of the main cognitive abilities we rely on every day, and is a core aspect of learning, academic performance, intellectual development, reasoning, and experience.
Processing speed is a cognitive ability defined as the time it takes a person to process a situation or stimulus and develop a response. It is related to the speed at which a person can understand and react to the information they receive, whether it be visual (letters and numbers), auditory (language), or movement. In other words, processing speed is the time between receiving a stimulus and responding to it.
Poor processing speed does not mean that a person is unintelligent, but rather that some determined tasks may require more time to perform, like reading, doing math, listening and taking notes, or holding conversations. It may also interfere with executive functions, as a person with slow processing speed will have a harder time planning, setting goals, making decisions, starting tasks, or paying attention.
Some examples of how we slow processing speed might affect our daily lives:
Does it take you an hour to do an assignment that takes others only 30 minutes?
Do you have a hard time following instructions or planning a specific activity, especially when you don’t have a lot of time to finish it?
Do you do poorly on exams, even when you know the material?
Working memory, or operative memory, can be defined as the set of processes that allow us to store and manipulate temporary information and carry-out complex cognitive tasks like language comprehension, reading, learning, or reasoning. Working memory is a type of short-term memory.
Working memory, according to Baddley and Hitch, is made up of a few systems, which include components for information storage and processing.
The Central Executive System: Works like an attention supervision system that decides what we pay attention to and how to organize a sequence of operations that we will need to do to do an action.
The Phonological Loop: This allows us to manage and retain spoken and written material in our memory.
The Visual-spatial Agenda: This allows us to manage and retain visual information.
The Episodic Buffer: integrates information from the phonological loop, visuospatial sketchpad, long-term memory, and the perceptive entrance into a coherent sequence.
Working memory refers to the ability that allows us to retain the elements that we need in our brain while we carry-out a certain task. Thanks to working or operative memory, we are able to:
Integrate two or more things that took place close together. For example, remembering and responding to the information that was said during a conversation.
Associate a new concept with previous ideas. It allows us to learn
Retain information while we pay attention to something else. For example, we are able to prepare the ingredients that we need for a recipe while we talk on the phone.
We use our working or operative memory on a daily basis for a number of tasks. When we try to remember a telephone number before writing it down or when we are immersed in conversation: we need to remember what was just said, process it, and respond to it by giving our own opinion. When we take notes at school: we need to remember what the teacher said so that we can write it down in our own words. When we do mental math in the supermarket to see if we have enough money to pay.
Visual scanning is the ability to efficiently, quickly, and actively look for information relevant to your environment. It is what makes it possible to find what you’re looking for using just your vision. Visual scanning is an important skill for daily life and makes it possible to efficiently carry out a number of different tasks.
Visual scanning is a function of visual perception that is aimed at detecting and recognizing visual stimuli. When you want to find something in your around you, your brain will automatically go through a series of interrelated processes:
Selective and Focused Attention: You need to be aware and focused on a stimulus in order to find it. Focused attention refers to the ability to focus your attention on a stimulus. Selective attention, however, is the ability to pay attention to a single stimulus when there are distracting stimuli present.
Visual Perception: Makes it possible to distinguish, identify, and interpret shapes, colors, and lights. This is when you make sense of the information that you receive from your eyes.
Recognition: Comparing the visual information you receive to determine whether or not you have prior experience with said information.
Visual Scanning: Looking through all or part of your field of view to try to compare what you’re seeing to what you’re looking for. You will stop looking as soon as you recognize the information that you’re looking for.
If any of these processes are altered, it would be impossible to locate a target object, either because you can’t find it (poor attention), because you can’t distinguish the object from its surroundings (poor perception), because you don’t recognize the stimulus (poor recognition), or because you don’t properly scan the area (poor visual scanning).
There are a number of jobs that require visual scanning. Police officers or members of the military have to be able to quickly and precisely detect objects that may be dangerous. Store employees have to use visual scanning to keep an eye out for products that may be misplaced or clients that need help. Almost any job has some level of a visual component that requires good visual scanning.
Students are constantly using visual scanning at school, whether it’s to pay attention to the board, read a book, or understand a presentation. It would difficult to study new material if the student is unable to find the word or idea in their notes or textbooks when they are trying to review the information before a test.
Driving requires you to constantly be on the lookout for other cars, accidents, potential hazards, traffic signs, pedestrians, and a number of other objects or situations. Poor visual scanning may inhibit your ability to successfully scan the environment for potential problems, decreasing your driving ability.
Visual scanning is an essential part of playing sports. Most sports require you to easily and quickly scan the space for relevant stimuli, which may be teammates, rivals, a ball, a goal, or any other vital component of the game. If you are playing football and want to pass the ball to a teammate, you have to visually scan the field to find him or her and then pass the ball to them.
How to play the game
The objective of Digits is to organize the various numbers in an ascending and/or descending order, based on the rules indicated at each moment. As the level increases, the quantity of numbers to order will also increase. Users need to stay focused and order the numbers as quickly as possible—trying to avoid mistakes which can cause them to lose points—before the time runs out.
One of the fundamental parts of mathematics is the numerical value— that is, if one figure is greater than, equal to, or less than another. Although this is something that we learn in childhood, and most of us understand this concept very easily, it can be challenging to apply it in the real world when under pressure.
CogniFit’s newest game Digits presents an engaging and fun way to train the cognitive skills that can help us to keep a sharp mind and boost our abilities related to numerical value.
From the very beginning, CogniFit has been keenly aware of the importance of using good data. Our tools for cognitive assessment and stimulation are conceptualized, planned, and developed with accurate, scientific data in mind, which has allowed our platform to grow into a tool used not only by individuals around the world who want to give themselves or their loved ones a brain boost, but also education and healthcare professionals who need a powerful platform for assessing, tracking, and training the cognitive abilities of their students and clients.
But that isn’t the only way CogniFit creates value through data. The massive amount of data generated by our platform can be used by scientific researchers as well, providing a unique source of information on cognitive abilities and how these abilities play an integral role in everything we do. CogniFit has chosen to use Amazon Web Service platform to create a valuable data ecosystem, allowing us to simplify our data storage processes, streamline the way we use and interact with our data, and supercharge our ability to create value from data for our customers and our research partners.
How CogniFit uses Amazon Web Services To Bring Even More Value to Our Cognitive Data
We chose to use Amazon’s AWS platform as a key part of our data infrastructure because of the power and relative simplicity of their platform. Here are a few examples of how we use AWS:
Simplifying Data Storage
CogniFit’s physical data is split between two main databases which keep separate personal information used for applications such as registering on our website and making payments from the data created by our applications which include information which might indicate, for example, a user’s physical or mental health status.
While there are multiple reasons for the way our physical data storage is organized, the personal privacy of our users is paramount among these. However, there may be times when we need to compare data which might reside on one database, such as a user’s ability to visually focus on a single stimulus, with data from another, such as age.
By using the AWS Database Migration Service to create data buckets in the Simple Storage Service, we are able to create a simple and safe data ‘sandbox’ where we can manipulate our data without putting our user’s information at risk.
In addition, we use Amazon’s RDS (Relational Database Service) to help us simplify the way we manage our databases. Using the AWS EC2 (Elastic Compute Cloud) to host our Front-End servers, we are able to take advantage of powerful load-balancing and autoscaling features to adapt our system to the variable traffic demands throughout the day, meaning we can seamlessly provide our users with peak performance during the high traffic periods without wasting server resources during low traffic periods.
Not only does AWS provide us with fantastic tools to create a powerful, efficient, and flexible data storage plan, through Amazon’s WAF (Web Application Firewall), we are able to ensure our web apps are safe and secure from online threats.
Streamlining Data Processing
With the data tools such as AWS Glue, we are able to refine, filter, and process data in new and powerful ways, allowing us to turn raw data into organized, valuable information.
The creation of virtual databases using tools such as the AWS Glue Crawler and the AWS Glue ETL Jobs allows us to build simple yet powerful sources of data for a variety of internal and external applications.
In this way, we can build individualized databases, specifically designed to meet the requirements of each data application.
Supercharging Data Analysis
Of course, data—even perfectly organized data—isn’t worth anything if we aren’t able to understand it and see the stories it is trying to tell. That’s where AWS tools such as SageMaker, Athena, and QuickSight come in.
If the tools in the toolchest of AWS Glue helped us turn data into information, these tools help us turn information into insights.
SageMaker is giving our data science department and software development teams the ability to create hyper-personalized recommendations and adjust complexity and difficulty of cognitive tasks on the fly to give our users the best possible experience and outcomes.
In addition, the business insights coming from QuickSight help us to understand our business like never before, shining new light on our user’s behaviors and needs.
But gathering and processing data is only one part of how we create incredible value for our partners and customers. Our priority is to deliver powerful solutions based on our unique cognitive data.
Amazon’s Cloudfront CDN allows us to deliver data, applications, and APIs to our researcher and developer partners globally with low latency and high transfer speeds, as well as to deliver engaging and challenging cognitive training and assessment tools to our customers safely, effectively, and quickly.
Amazon Web Services has allowed us to push our data even further than before. The integration of tools such as Simple Storage Service, AWS Glue Crawler, and SageMaker into our data infrastructure has unlocked new potential for our data.
Epilepsy is a unique neurological condition characterized by unpredictable seizures and other health problems. But even though it is the 4th most common neurological condition and affects more than 65 million people worldwide, there are often misconceptions and lack of general understanding of what Epilepsy is.
While many people have heard of the disorder, many have an incorrect understanding of what Epilepsy is, assuming the someone with this disorder will instantly go into seizure at the sight of flashing lights.
These less visible effects of Epilepsy drew the attention of researchers from Impulso Cognitivo and the University of Antonio de Nebrija in Spain, who have developed a study using CogniFit’s Platform for Researchers to investigate the influence that cognitive training for executive functions has on the cognitive abilities of adults with Epilepsy, and whether it can potentially mitigate these secondary cognitive effects.
The “EpiCog” Project from Impulso Cognitivo and the University of Antonio de Nebrija
Research scientists, lead by Jon Andoni Duñabeitia Landaburu and Maria Calvo recently began their investigation, working with 80 patients with Epilepsy between the ages of 18 and 60 years old, and will continue to work with the participants over a period of months.
At the beginning of the study, each participant was given the CogniFit General Assessment Battery to determine a baseline score for several cognitive abilities. After this initial measurement, participants were randomly assigned to groups. The control group were tasked with playing CogniFit games without the active training algorithm to adjust difficulty and present participants with a challenging cognitive exercise. The second group were tasked with completing CogniFit games using the unique training algorithm, providing a more challenging cognitive training regimen.
The Epilepsy Training contains 19 Stimulation Games (to strengthen cognitive abilities), 8 Assessment Tasks (to measure progress) and focuses on measuring 4 Cognitive Skills: Inhibition, Monitoring, Working memory and Cognitive flexibility.
When to Expect Analysis and Results
This unique research project will take place over the next months, after which point the research team will compile and analyze the collected data, with results expected to be ready in the summer of 2021.
Our world has been greatly affected by the presence of the automobile; from the way we design our metropolitan and national infrastructures, to the way we relax and vacation, to the way we run our errands and get to work.
The automobile has made our lives easier in many ways and has given millions of people around the world freedom of movement that would have seemed impossible only a few hundred years ago.
As the automobile became more and more intertwined into our societies, so to have the inherent dangers of operating these machines. Signs, signals, and safety features were added to the roads, and seat belts, air bags, and—more recently—Advanced Driver Assistance Systems such as automatic breaking and lane departure warnings were added to vehicles to help prevent these risks. But even with the addition of these safety systems, there is still an inherent risk any time a driver gets behind the wheel.
CogniFit as an Investigative Tool for Predicting Vehicle Accident Risk
CogniFit’s tasks for measuring estimation capacity (included in the driving test) has been used by the Center for Cognitive Science of the Nebrija University of Madrid in collaboration with The Arctic University of Norway to investigate cognitive and psychomotor risk factors associated with traffic accidents, as well as to develop a unique estimation index that can help predict the risk of suffering a traffic accident.
The main objective of this research was to show if older drivers have more accidents and if these tend to be more serious. To do this, they have carried out a comparative study where they have looked to see if there really is a relationship between the score obtained in the estimation tasks of the CogniFit driving test and the number of total accidents.
Subsequently, it has been reviewed whether, in addition, the CogniFit scores provide an additional benefit for the prediction of any type of car accident.
How was the CogniFit Estimation score developed?
The researchers analyzed data collected through the CogniFit platform on the cognitive skills related to estimation ability of 20,231 participants (10,627 female, 9,606 males) across 123 countries. The data, measuring participants’ ability to estimate the duration, speed, and distance of stimuli, as well as their understanding of how the speed and distance of an object affected its movement, were compiled into a composite index measuring each participant’s estimation abilities.
Subsequently, the mean percentages of precision for both men and women on the CogniFit tasks were compared to raw data from male and female drivers involved in 1) fatal crashes, 2) injury crashes, and 3) crashes with material damage.
Finally, an analysis was carried out where the data of the different types of accidents were related by type and sex of the total, and the age of the drivers, their gender, and their CogniFit score as predictors.
The results showed a predictive power of age, and gender, showing that older drivers were involved in fewer fatal accidents than young people and that women had fewer fatal accidents than men. The CogniFit score also showed a direct relationship between a person’s estimation skills and the number of fatal accidents.
How can the CogniFit Estimation score help?
Based on the findings of the analysis of data and the robust relationship between CogniFit’s Estimation score and various types of traffic accidents, we can see that the CogniFit Estimation score can predict the group probability of being involved in a fatal car accident (accounting for 98.3% of the variance), of being involved in an accident with injuries (explaining 96.2% of the variance), and of being involved in accidents with material damage (explaining 95.8% of the variance).
Understanding how age, gender, and the cognitive skills related website to estimation affect the risk index of drivers serves not only to know which drivers are most at risk of suffering fatal vehicle accidents, but can also serve as the basis for future research into whether training these core cognitive skills can reduce the risk of accidents in the future.
How can CogniFit help you understand your driving risk?
The results provided by this neuropsychological assessment include relevant information that can help predict the quality of vehicle handling and identify the risk index or accident tendency of a driver.
This digital driving test is performed online and lasts approximately 30-40 minutes. At the end of the evaluation, users receive a complete report of results with useful and comprehensible information about driving ability, performance, and cognitive skills.
Whether you or a loved one have been driving for decades or are preparing to take the driver’s license exam for the first time, the Driving Cognitive Assessment from CogniFit can help you feel confident you understand your driving risk.
Brain plasticity or neuroplasticity is the ability of the brain to grow and change with age, be it for better or worse. It does so by organizing neurons and synaptic connections. As per neuroscientists, neuroplasticity is the ability of the brain to make and reorganize synaptic connections in response to learning experiences and injuries. This flexible growth of the brain plays an incredible role in its development and shapes distinct human personalities.
The brain has a very complex composition and set up. It has a gray matter that can either thicken or shrink, it has sensory and motor signals working in parallel, its neural connections can refine or weaken, etc. However, all these physical changes in the brain are very important for the individual abilities of a person.
Every time you learn something new, it reflects a physical change in your brain. The brain makes new neural pathways that tell your body to carry out what you’ve learned. Moreover, every time you forget something, it too is a reflection of a physical brain change; your neural wires and pathways may have degraded or severed. This exceptional ability of the brain to modify its existing neural connections and wire-and-rewire itself is what is called brain plasticity. Without it, no brain can develop from childhood to adulthood and recover from injuries or traumas.
How does brain plasticity help your brain grow and heal?
The basic brain structure is defined by your genes before birth. However, the continuous development of the brain heavily relies on developmental plasticity. It is characterized by the developmental processes that change the synaptic connections and neurons in the brain.
When your brain is immature, neuroplasticity aids its growth by;
Making or losing synapses
Migration of neurons throughout the brain
Sprouting and rerouting of neurons
As the brain grows, neurons mature. They send out carious branches like axons and dendrites from transmitting and receiving information. Also, they increase the number of synaptic contacts. With age, when you learn new languages, activities, and skills, neuroplasticity helps the brain to devise neural connections that help you to remember the stuff in the long-run. It promotes structural and biochemical changes at the synaptic level which eventually helps the brain to grow strong with memory.
In the mature brain, there are few parts where neurons are formed e.g. the dentate gyrus in the hippocampus which controls emotions, and the sub-ventricular zone in the lateral ventricle. Neurons generate here and migrate through the olfactory bulb which processes the sense of smell. The information stored in the nascent neurons contributes to the brain to recover from damage. As we grow old, our brain starts losing cells and neural connections leading to mental decline. Neuroplasticity helps the damaged area of the brain to recover by forming new neural connections and encouraging sensory and motor stimulations.
Can brain plasticity cause our brain to shrink or become weaker?
Until now must have been considering neuroplasticity as a hero but neural changes are not good always. When neuroplasticity affects your brain negatively, it is called negative brain plasticity. The effects of negative plasticity can lead to destructive addictions, undesirable habits, and negative self-talk which are potentially hard to change. For example, improper synaptic changes and connections due to negative plasticity cause learning and behavioral disorders.
In the case of negative plasticity, synapses grow weak and the small spine structures supporting them grow small. This leads to a breakdown of the structure and function of the brain. It might cause your brain to shrink. One such example of negative plasticity causing a shrink in the brain size is the domestication of animals. A domesticated animal reportedly has a smaller brain as compared to the wild ones. For example, when it comes to hunting food, why are wild wolves considered smarter than domesticated dogs even when the dog is trained enough to read humans?
This is because domesticated dogs have lost their brainpower required for hunting and their brains have grown smaller. If your neural connections aren’t formed properly or if you are not using your certain neural powers, you will start losing your brain chunk by chunk.
How can we use brain plasticity to our advantage?
Brain plasticity can widely be used for a variety of advantages. There are many ways in which brain plasticity benefits your physical and mental wellbeing. Some of the most important benefits, brain plasticity can be used for, are listed below.
Recovery from strokes
A stroke occurs when the blood supply to the brain is cut off. It deprives the brain cells of oxygen and nutrients and if prolonged it can cause the cells to die, seizing the brain function. Neuroplasticity can help the brain to recover the damage due to stroke. It works around the dead cells and helps to construct new neural pathways triggering the rehabilitation process.
Recovery from mental illnesses
Mental illnesses occur due to affected neural networks. They hamper the signaling of the brain and deteriorate its neural connections. Neuroplasticity helps to repair these neural networks resuming proper signaling and restoring healthy synaptic connections. In this way, it potentially helps with the recovery from mental illnesses.
Neuroplasticity has the incredible benefit of strengthening senses. If a certain area of the brain controlling a particular sense is damaged, the brain can rewire the function and some other area might pick it up. Also, losing function in one area enhances the functions in the other areas. For instance, if you’ve lost a sense, neuroplasticity may heighten the others. This is the possible reason for why do blind people have exceptional hearing. They may not have the sense to see but have a high hearing ability.
Enhanced memory and learning
As mentioned above, whenever you learn or memorize something new, your brain undergoes physical changes to retain it. For example, if you’ve learned a new language, your brain will start making new pathways and trigger synaptic connections that will help your body know how to do it well. Every new lesson that you will learn will potentially connect new neurons and change the default mode of your brain’s operation. It is likely to enhance your memory and learning abilities. The healthier the neural connections, the greater will be your cognitive abilities enhancing memory, learning, and other mental abilities.
Does brain plasticity decrease as we get older?
A simple answer to this is yes, it does. As an individual ages, the brain grows but the rate of neuroplastic changes declines. However, it is never likely to stop because neurons keep appearing in different parts of the brain until death.
The younger brains i.e. from birth to two or three years display maximum brain plasticity. There is a huge increase in the number of neurons and synaptic Stromectol online connections in this age. This is because, the child is learning the basic functions and skills of life like eating, walking, talking, etc. Toddlers are expected to have twice the synapses of an adult. Later, the number of synaptic connections is likely to reduce by half till adolescence. During youth and adulthood, the human brain undergoes pruning which is the reduction of neurons and synapses formed during an early age. This reduction is mainly influenced by the life experiences of an individual.
Brain plasticity might decrease with age but never halts. It continues in adulthood or older age because people keep learning and experiencing new stuff which causes the brain to elevate the synaptic count. Healthcare experts recommend certain tips that can help to augment brain plasticity. A few of them are as follow;
Get enough sleep
Practice brain-stimulating exercises
Continue learning new things to challenge your brain
Read as much as you can and enhance your vocabulary
Play challenging games that demand brainwork
Neuroplasticity or brain plasticity is an exceptional phenomenon where your brain organizes neural connections for enhanced working. It happens as a result of two situations; either you are learning something new or your brain has encountered an injury or trauma. In both the cases, the brain works to wire and re-wire its neural pathways by potential synaptic connections.
This ability of the brain to form new connections is necessary for its healthy growth and development. As it enhances the cognitive abilities of an individual and eases mental and emotional unrest. Most importantly, it offers greater healing effects against injuries like stroke and various mental disorders. There are chances that the brain might fall short of its neuroplastic abilities but the situation can be improved by simple self-help techniques mentioned above. Considering the wide effects of brain plasticity, people are recommended that they should help their brain continue with this super power by adopting a healthy lifestyle and keeping their brain active.
Early childhood development refers to the physical, psychological, and emotional growth of the child. This period of development can last from the time an individual is born until they reach adolescence or the beginning of adulthood. During the developmental process, the child learns the basic skills of life, develops and navigates complex emotions, and learns to relate with peers by participating in social interactions. The whole process can be thought of as the child progresses from stages of dependence to an independent life.
Early Childhood Development: What You Need To Know
Early childhood development is significantly influenced by genetic factors, prenatal experiences, and the environment of early childhood. By environment, we mean the type of surroundings in which the child is growing, what events they are experiencing, the behavior of the parents and caregivers, etc.
Cognition: The ability of an individual to think, learn, and solve problems
Social and emotional interactions: The development of social links and emotional attachments
Speech and language skills: The ability of a child to learn a language, read, and communicate with others.
Physical/Motor skills: The ability to control the body through both fine and gross motor skills.
Sensory awareness: The ability to perceive and process sensory information for future use
Understanding the stages of Early childhood development is important because it can help parents understand if their child is on the right track or not. The stages are not hard-and-fast rules that each child must meet at the same age, but rather serve as checkpoints, letting parents know about how well their child is growing physically and psychologically. Children with poor early childhood development are often left behind in their academic careers which hampers their personal and social life as well.
If your child isn’t developing as per the normal standards, there are plenty of ways to help promote healthy development, and it may be beneficial to take them to a trusted pediatrician who can help you with tips to nurture your child’s development. But how would you know that if your child is on the right track? Well, we are here to help you with it. So, keep reading.
How Can A Parent Know If Their Child’sDevelopment Is On Track?
There is no tracking device or alarm system that can notify you of your child’s early developmental progress. It is you who have to keep an eye on certain milestones that will help you know about the growth and development of your child. Just the way you keep tracking his height and weight, it is important to keep tracking cognitive and psychological development as well. For example, in the first few months after your child’s birth, you will clearly notice the signs of motor and language skills.
Your child will start moving their fingers, looking here and there. They will try to answer you with a smile or facial expressions. He or she might not be able to produce proper words but will try to make sounds, etc. If this isn’t happening to your child, it may be a sign they are facing a developmental delay and that you may need to consider consulting an expert.
For your ease, we have summed up some major milestones that a child might achieve by a certain age based on typical developmental progress. Consult the list and see if your child is doing what the majority of his age group’s children do.
Developmental Milestones: Birth to 1 Year
It is the most crucial year of growth as every month will offer something new!
In the first 2 months, your child may begin smiling when hearing your voice and follow you with their eyes when moving here and there.
By 3 months, when they lie on their stomach, they should be able to raise their head and chest and start smiling at other familiar people who are always around.
By 4 months, they may begin to imitate sounds, hold their head steady, laugh, and babble.
By 6 months they may begin moving little objects with hands.
By 7 they may respond to their name.
By 9 months they may begin crawling, sitting with support, and saying words like mama, papa, etc.
Finally, by 12 months, your child may start walking with support and respond to people around and imitate people.
Developmental Milestones: 2 Years
Between 1-2 years, the child may begin walking independently, holding objects like cups, start a little running and jumping, speaking short sentences, following instructions, etc.
Developmental Milestones: 3 Years
By 3 years, the child may have started climbing, speaking multiple words and sentences, and sorting objects by colors and shapes.
Developmental Milestones: 4 Years
By 4 years children may start getting along with people who are outside the family e.g. neighbors, parent’s friends, or the non-family people they meet every day. They may have developed gross motor skills for activities such as riding a tricycle, as well as fine motor skills for drawing circles, squares, and other simple shapes.
Developmental Milestones: 5 Years
By 5 years, many children have developed the cognitive skills required to remember important complex information such as their home address, as well as complex motor skills for activities such as skipping and jumping or get dressed. They should also be able to count objects, etc.
Now considering your child’s age, compare what they are doing compared to the previous generic milestones. If there is a huge gap, it may be a sign of developmental delay. There is no need to panic, everyone has a different cognitive setup. Try to consult a doctor and work on helping your child.
What Are The Key Stages Of Early Childhood Development?
The developmental milestones listed above cover a wide range of behaviors and transformations that take part in shaping the brain and personality of a child. Most of the behaviors are learned in the first few years of life rendering them the crucial stage of early childhood development. However, this isn’t where the process ends. Childhood development continues in middle and late childhood or adolescence as well.
Broadly, there are three key stages of early childhood development i.e.
Late childhood or adolescence
The first one refers to the time from birth to eight years. These are the years of the most obvious growth and development. During these years, a baby who is totally dependent on his parents transforms into a walking, talking, and independent individual. It is the time when the child’s life functioning, personality, and relationships are shaped. He/she develops emotional attachment with people around them and their behavior affects the child the most. He starts learning words and language for communication along with basic life skills like walking, talking, eating, reading, writing, etc. It is also a crucial time for physical growth as well.
Middle childhood refers roughly to eight to twelve years of age. The child starts understanding some abstract concepts like money and time. Moreover, they start developing interpersonal relationships and cognitive skills.
Adolescence or late childhood starts at twelve and ends at the teenage years. It is the time when an individual experiences major changes in their physical, emotional, and mental growth. Your child is likely to encounter psychological disorders, hormonal changes, fluctuations in behaviors, etc. He/she might struggle with their emotions causing mental unrest.
Is It OK If My Child Isn’t At The ‘Right’ Stage?
Delays in early childhood development may cause many difficulties for children at various stages of life. Poor development in early childhood can continue to affect the individual throughout their life into adulthood. For instance, poor physical growth can hamper his abilities to participate well in extracurricular activities like sports at the school.
Also, poor psychological web page development may cause poor cognitive abilities which are likely to affect the academics of the child. Poor mental and emotional development may cause your child to suffer from various mental disorders. Thus if you sense that your child isn’t at the right stage, consult a pediatrician as soon as possible. Note, this is nothing to worry about, you can fix the situation with simple everyday techniques as follow.
How To Help Nurture A Child’s Psychological Development?
Here are some tips for nurturing your child’s psychological development.
Practice mentally challenging activities such as puzzles or learning games
Read stories and participate in creative games
Help your child to recognize and accept his feelings
Empathize with him/her to build trust
Spend time with your children and do what they love to do
Model good behavior because children imitate what they see
Appreciate their little efforts
Help them build resilience
Seek medical advice
All these tips will help you to elevate and nurture your child’s psychological development.
Early childhood development is a developmental process that shapes the personality of your child. It is a crucial process that needs special attention because it depends greatly on the prenatal behaviors and the environment around the child. Parents must keep a check on what is their child seeing and observing. They must ensure that their child is safe from any kind of negativity that can hamper his growth in any way. Most importantly, the parents should model good behavior before their children so that they imitate them in their lives.
For us at CogniFit, like for so many others, 2020 was a year of great changes. For us, it was a year for focusing internally on modernizing and streamlining how our platform and tools work, improving the user experience through increased interaction with the community and a renewed focus on UX design, at the same time we saw tremendous growth in the community of CogniFit users as people searched for ways strengthen their mental and cognitive health in response to a global pandemic.
While we are pleased to welcome so many new users to the CogniFit community, we are well aware that much of the growth was, at least in part, due to the global COVID-19 pandemic and the very real effect it has had on the mental health of so many. Because of this, we have taken great care and pride in our efforts to build not only great products and services that have a real and lasting benefit to our users but also in our efforts to build a thriving, supportive community for our users.
Our New Year’s Resolution: A New Launch Each Month
We want to continue growing and building the best possible CogniFit and continue to provide the highest quality of services to those who have placed their trust in our platform to strengthen their cognitive abilities through our scientific cognitive evaluation and brain training tools.
In 2021, building on the behind-the-scenes milestones of the previous year, we have chosen to introduce a new highly-visible challenge for ourselves: To publish a new brain training game each month for our users to enjoy.
Like all CogniFit games, these new games will offer unique, engaging experiences designed to stimulate the vital cognitive abilities we use each and every day, and like all CogniFit games, they are created by experts in neuroscience, and designed with a scientific and academic focus.As
As we always say: At CogniFit, we don’t make games, we make unique experiences!

We’re Proud to Announce the First of Many New Games: Color Bee
And we are overjoyed to be able to announce today the first of many brain training games for 2021, Color Bee!
If you are anything like me and often feel a bit like your coordination isn’t as strong as it once was, that your mind used to be quick as a whip but that it now takes a fraction (or more) of a second longer for your brain to respond, or you find that you simply aren’t as agile as you once were and need to keep an eye out for pesky doors and table corners to avoid bumping into them, then Color Bee might just be the perfect brain game for you.
This deceptively simple, exciting game is more than just a fun way to pass the time; It has been designed purposefully to train specific cognitive abilities in a simple and exciting way.
Color Bee has been developed with three key cognitive abilities in mind: Spatial Perception, Hand-Eye Coordination, and Response Time. By challenging users to quickly navigate a complex visual scene while staying alert to dangers, obstacles, and changing goals, Color Bee is a fantastic way to put these critical cognitive skills to the test and to push yourself to new heights as you progress to higher levels and more complex challenges.
Let’s take a look at these core cognitive abilities, how they help us with tasks, both simple and complex, in our everyday lives, and what makes them so important to everything we do:
Spatial perception is the ability to be aware of our relationship to both the environment around us (exteroceptive processes) and with our own physical self (interoceptive processes). While this may all sound quite complex, it really comes down to this: Spatial Perception is what allows us to understand our environment and where we are within it.
Spatial awareness is made up of two processes, the exteroceptive processes, which create representations about our space through feelings, and interoceptive processes, which create representations about our body, such as its position or orientation.
If you have ever tried parking your car and when you saw a spot wondered “is that spot big enough for my car to fit?”, you were using the exteroceptive process to understand and evaluate your environment.
If you have ever been walking along the sidewalk and effortlessly walked up a few stairs without really thinking about it, you were using the interoceptive process to understand the position of your feet and raise them at the correct moment.
If you have ever walked into your kitchen and smashed your little toe on the kitchen table, then you have experienced what it is like when your exteroceptive and interoceptive processes don’t work as well as they should.
Spatial Perception is what allows us to complete complex tasks such as drawing, driving, or playing sports without going outside of the lines.
Hand-eye coordination is the ability to coordinate activities that require the simultaneous use of our hands and eyes
Activities that require us to use the information our eyes perceive (visual-spatial perception) to guide our hands to carry out a movement rely on Hand-Eye Coordination.
When we reach to grab an object, we use the information gathered through our eyes regarding the shape, size, distance, and even speed of the object to inform our hands how to manipulate the object.
We use Hand-Eye coordination for an almost limitless amount of activities we perform every day, from driving to drinking a glass of water, even activities as deceptively simple as walking or waving our hand require the use of Hand-Eye Coordination.
Response Time, sometimes called reaction time, refers to the amount of time that takes place between when we perceive something to when we respond to it. It is the ability to detect, process, and respond to a stimulus.
Response Time is one of the most important cognitive skills because nearly everything we do relies on our ability to process information and develop an appropriate response.
You have likely noticed that when you are wide awake and full of energy you are able to quickly reply to questions, react to changes in your environment, or respond to perceived rustburgpharmacy dangers much more quickly than when you are completely exhausted the morning after a poor night’s sleep. This is a very obvious example of how changes in our bodies can affect Response Time, however there are more gradual, less noticeable changes that happen over time due to the effects of age, poor diet and exercise, or physical and mental illnesses.
Maintaining an active and stimulated mind is one of the keys to promoting healthy Response Time so we can continue to safely enjoy the many activities that rely on this cognitive ability.
So whether you are looking for a way to specifically train Spacial Perception, Hand-eye Coordination, or Response Time, or you simply want a fun game with some great cognitive benefits, Color Bee is a fantastic choice for you and your loved ones!
How to Play Color Bee?
Players must stay focused so they can guide the bee towards the leaves of the designated color, avoiding leaves of other colors as well as obstacles. Sounds simple? Just wait. As the levels increase (and as you get more skilled) the difficulty rises.
Spin the bee around the plant to find the right leaves using the Left and Right Arrow keys and tell it when to dive down using the Down arrow key.
We hope you enjoy Color Bee as much as we do and are looking forward to hearing your stories about your cognitive improvement using Color Bee and all of the CogniFit games and tools.

Traumatic events in early childhood have prolonged effects on the mental health of an individual. Brain, in early childhood, is the most vulnerable. Bad experiences negatively impact its development, increasing the risks of early life adversities. These adversities are a major risk factor for the development of various behavioral and psychological problems in later life. Research studies report that children who experience maltreatment have a higher rate of developing depression, anxiety, PTSD, suicidality, and other mental health disorders.
Also, distressing early life events contribute to higher drug dependence in later life. This is the reason why healthcare experts urge parents to focus on the early childhood mental health of their children. Healthy early childhood mental health is very beneficial for the healthy psychological and behavioral development of an individual. The greater the start, the more pleasant will be life later on.
This article is presented exclusively for a comprehensive understanding of our readers regarding early childhood mental health, why is it important, and how can it be improved. So, let’s begin.
What is early childhood mental health?
Early childhood mental health refers to the social, emotional, and psychological development of children in their early life. Early childhood mental health means the ability of a child to explore, learn, make relationships, communicate, or express their emotions, and finally respond to relationships and the care given to them.
The word early-childhood refers to the first 3-4 years (or maximum 5) of a child’s life. It is the time when he/she is learning to function both, socially and emotionally. Whatever the children see or experience is likely to stay with them for a lifetime. It is the time when their brain and especially mental health is developing. The treatment they get and the interactions they make will shape their brain and mental health. They are at the age of exploring and learning, they’ll perceive the world through the actions and treatment of the people around them.
Experts from the Center on the Developing Child, Harvard University say that the early experiences of a child, whether negative or positive, affect his/her brain development. The first three years are the most crucial time because children are growing both physically and mentally. By three to four years, the child has made enough connections to draw a picture of the world. Therefore, it must be made sure that a child, at this age, has most of the positive and compassionate behavior so that his brain and mental health nurtures well.
What happens when a child has poor early childhood mental health?
As mentioned before, early life experiences shape the mental development of an individual. Pleasant experiences lay the foundation of sound mental health and unpleasant ones are likely to impair the mental capabilities of an individual. They are likely to have lifelong implications affecting the cognitive, learning, and memory-related abilities of a child. The child may not show up with mental health disorders at a younger age but clear characteristics of various mental health disorders can be seen in later life. Some of the disorders that commonly appear as a result of poor early childhood mental health are;
Posttraumatic stress disorder
Neurodevelopmental disabilities like autism (visible at an early age)
You must be wondering how early life events can promote such situations. Well, experiences leave a chemical signature on the genes. This “experience-gene expression” intervention affects childhood mental health. Genes carry instructions telling our bodies how to work. However, the chemical signature due to stressful experiences prevents the genes to carry out their functions successfully which lays an unstable groundwork for mental health. The common stressful events causing such conditions include poverty, recurrent abuse, chronic neglect, substance abuse, domestic violence, parents’ mental health, parents’ unhappy relations, etc.
Since the damage caused by poor early childhood mental health is much severe, you must work on the healthy development of your child’s early mental health. To help you with this, we present some amazing tips to nurture early childhood mental health.
Tips to nurture early childhood mental health
There is neither any prescribed medicine for improving the mental health of a child nor a super trick that can do this for you. It requires careful and sincere efforts to nurture your child’s brain and support their mental health. Most of the time, it is the everyday activities that can significantly help you with it. Always remember it is both a time-and-energy-consuming process but it will all be worth it in the end.
Here is what you need to do.
Teach your child to recognize his feelings
The “language of feelings” is the first step of your child towards a healthy mental state. You have to make him/her identify what they are feeling. Teach them words for different emotions so that they can tell you. Most of the children cannot let their hearts out because they are confused about how they feel about a particular thing.
They don’t know whether it is actually a problem or it is just a mixed feeling. Many of them think that feelings other than happiness are bad and shameful but you’ve to tell them that it is normal not to be happy all the time and have different feelings. Tell them to express themselves, no matter how they feel. The more they’ll express, the lesser will be their stress.
Empathize to build trust
Sympathies are never enough, you need to empathize with your children. You need to put yourself into their shoes, pause, and realize how your child is feeling. Getting angry at once and giving advices without listening to them won’t work.
Help your child to put their trust in you. For that, you have to listen to them openly so that they know somebody is there for them. Observe your child’s behavior, notice what upsets them, reach out to them, validate their feelings, know their viewpoint first, and then present yours. There are chances that your child may be overreacting to something but still, hear them out to reduce their defensive reaction.
Make your child do what he/she loves to do
Creativity is a natural way to express yourself. Similarly, children are likely to express themselves when they are doing something they really enjoy. It can be anything like playing games, sports, drawing, dancing, photography, role-playing, their favorite toy, etc. You need to find out what your child loves to do and then encourage them to do it often.
Try to do it with them. In this way, you can spend maximum time with your child. You can talk to him/her about their thoughts, what they want to be in the future, and how they feel. Most importantly, you’ll know what your child is up to. Most of the parents leave their children to TVs and Smartphones which is very bad for the development of their brain. So, try to encourage the creativity of your child and allow them to pursue it.
Model good behavior
Children imitate what they see. If they’ll see violence around, they’re likely to practice it in life. If they see their parents or care-givers fighting and abusing each other, they’ll perceive it as normal behavior and will continue with it through life. Therefore, it is necessary that people who are raising a child model good behavior. They need to be polite and careful with each other and the child as well. Good and kind acts positively affect the brain and provoke the child to do good as well. Remember that you are your child’s best teacher. If you want your child to do something, do it yourself first.
Appreciate them for their little efforts
This is the simplest yet most effective technique to nurture your child’s mental health. Recognize their small efforts and appreciate them. It will encourage them to work even harder next time. Give them constructive feedback. Highlight the goods and then tell them how they can improve more. Your appreciation is going to build their self-esteem which raises their confidence and resilience.
Create stimulating, playful environments
Young children are full of curiosity, playfulness, and thirst for knowledge and understanding of their surroundings. They are constantly observing, probing, and testing gulfport pharmacy how their environment works and how the people around them interact with it and with each other.
Promoting learning and mental stimulation in this early phase of discovery is vital in promoting a lifelong love of learning. Ensuring that children have access to stimulating environments including colors, sounds, shapes, and interactive activities helps the brain to build connections and reinforces the child’s curiosity and inquisitive nature.
Interactive toys and stimulating games and activities serve as an integral part of this rich learning environment.
Consult a medical professional
Mental health is an important and sensitive part of overall human health. So, consulting a specialist is a must. For that, you should talk to a pediatrician or a psychiatrist. You should ask them about the mental health skills and behaviors appropriate for different ages and any emotional and behavioral changes that can be looked forward to as a child grows. If you notice anything unusual in your child’s behavior, report it to the doctor, look for a plausible cause, and ask for a solution. A medical professional can guide you the best in this regard.
Early life experiences affect the mental health of a child to a great extent. Poor early childhood mental health increases the risk of developing mental disorders in the long run. Therefore, parents should focus on the early mental health of their child as much as possible. They should do whatever it takes to help their child grow mentally strong. The above-mentioned help tips can potentially serve to promote healthy mental growth in children. All they require is your dedication and efforts!
The waitress of the fast food joint asks, “Would you like fries with that?” The customer quickly requests a super-sized meal, while the woman at the neighboring orders a grilled chicken salad. Whichever dietary choice resembles your own, nutrition has a vast impact on how we think, feel, and behave. Why? Nutritional psychology explains how nutrition determines cognitive skills, mood disorders, and intelligence.
What is Nutritional Psychology?
Nutritional psychology is the study of nutrition and how it pertains to mood, behavior, and mental health. The foods we eat influence psychological, behavioral, cognitive, perceptual, sensory, and psychosocial patterns. This area of study has the goal to implement education and nutrition to connect diet with mental health.
Nutritional Psychology: The Enteric Nervous System
The nervous system is known to describe the brain and spinal cord; however, most are surprised to learn that a large portion of the nervous system is in our gastrointestinal tracts. From chewing food to absorption and even elimination, the gut is home to millions of nerve cells, hormones, and enzymes that perform a variety of functions. This is why it is commonly referred to as our second brain. Together, the gastrointestinal tract and all it entails is called the enteric nervous system.
Nutritional Psychology: Hormones
Gut bacteria line the stomach and intestines to facilitate digestion. These bacteria manufacture neurotransmitters not only to regulate digestion, but to control key cognitive processes like memory, mood, and learning. Serotonin is a particular prominent neurotransmitter in the gut. Bacteria create nearly 95 percent of the body’s serotonin—a neurotransmitter imperative to stabilize mood and trigger peristalsis (i.e. contractions of the stomach and intestines to digest food).
When serotonin is off, it can cause symptoms of nausea, vomiting, and constipation. But serotonin is not the sole neurotransmitter, GABA and dopamine are also relevant. Studies have allowed experts to document observations like mood changes in the presence of functional gastrointestinal disorders such as irritable bowel syndrome. It was once thought that emotions and disorders like anxiety and depression result in bowel symptoms, but scholars at John Hopkins now believe that an unhealthy gastrointestinal tract leads to anxiety and depression.
Nutritional Psychology: Food and Brain Structure
The food we consume literally has the power to alter brain structure. A 2018 study published in the Journal of Neuroscience reveals an increased volume of grey matter in the prefrontal cortex shown on brain imagine in patients who made food choices based on whether a food item is healthy rather than on taste or indulgence. Judging grey matter volume in these areas is a helpful predictor of various eating disorders including obesity and anorexia nervosa.
Neurons, nerve cells in the brain, are also affected by food. Diets with a high fat and sugar content have fewer synapses in the brain’s hippocampus—the connections that transmit signals to other cells in the body. The brain is less efficient at neuroplasticity. It cannot adapt as quickly. Instead, the hippocampus becomes inflamed as the cells respond to harm.
Nutritional Psychology: Obesity
The term obesity is described as having a body mass index (BMI) of 30 or greater. There are more than 400 million obese adults worldwide. Being overweight has a vast impact on the body. Although someone who is obese is prone to developing heart disease, diabetes, and hypertension, the brain is particularly effected. Scientists have attributed multiple cases of cognitive impairment with obesity.
The brain of obese individuals is vulnerable to cerebral atrophy. The brain literally shrinks. As the brain volume decreases in size, the likelihood of memory impairment increases with age. A lack of brain volume makes it difficult to refrain from excessive eating, which fuels the cycle.
Nutritional Psychology: Caloric Intake
The first line of defense against the obesity epidemic is to adopt a healthy diet and lifestyle. Diet and exercise are key to shedding the extra pounds because it burns more calories than one expends. However, restricting caloric intake is potentially detrimental to psychological health.
Studies show that caloric restriction is linked to depression—a mental health disorder characterized by feeling unexplained sadness, anxiety, loss of interest, low motivation, and interrupted sleeping and eating patterns for more than 2-weeks. Male subjects went from consuming 3,200 calories to 1,600 calories of foods such as potatoes, turnips macaroni, milk, bread, chicken, and rutabagas. These men reported a multitude of symptoms: dizziness, cold intolerance, fatigue, muscle aches, edema, reduced sex drive, low attention spans, poor concentration, and psychological distress. Some were even sent to a psychiatric hospital for self-mutualization and suicide attempts.
Contrarily, other studies conclude that the risk for dementia and cognitive decline is lessened by a lower caloric intake. The combination of studies supports that the quality of food choices are important. For our brains to thrive, we require a range of foods from all food groups to avoid nutritional deficiencies.
Nutritional Psychology: Carbohydrates and Cognition
Carbohydrates are the body’s main source of fuel. As carbs are consumed, the body breaks the carbohydrates down into glucose. The nerve cells utilize the glucose in the bloodstream for energy. Restricting carbohydrates, like so many of modern day dieters do, is depriving the body of its main source of fuel. Thus, cognitive skills are affected. Researchers at Tufts University tested this hypothesis. Women were placed into groups based on “low-carb” and “low calorie” diets. Their cognitive skills were tested before the study, during, and after. Those on low carbohydrate diets presented with poor memory performance within a week of their diet.
In the average Western diet, the type of carbohydrates has an impact too. Refined, processed carbohydrates result in repeated spikes in blood glucose levels which triggers the rapid release of stress hormones that increase anxiety and mood disorders.
Nutritional Psychology: Fatty Acids and Cognition
70 percent of the human brain is comprised of fat. Fats are critical for brain development. When the body does not have sufficient carbohydrates available, it uses fat to perform necessary functions. Psychiatrists at Harvard University discovered that the amount of fat an individual consumes has little impact on brain function; however, the form of fat does.
Omega-3 fatty acids are beneficial dietary fats. They are found in fish, walnuts, and chia seeds. Other fats, like saturated fats, are good in moderation and come from meat, coconut, and dairy products. Hydrogenated fats (i.e. trans fats) are best avoided in foods that are processed or deep-fried.
Nutritional Psychology: Vitamins and Minerals and Cognition
Vitamins and minerals are also related to brain function. The body is exposed to free radicals. Free radicals are unstable cells that damage healthy cells. The result is disease, aging, and illness. Vitamins and minerals contain radical fighting substances known as antioxidants.
The following vitamins and minerals are essential:
Iron—Adults and children who are anemic score lower on cognitive tests.
B Vitamins—B vitamins for the brain include B12, B6, and B9 (folate). When B vitamins are lacking, the body cannot convert homocysteine into protein. As homocysteine accumulates, cognitive performance suffers.
Vitamin C—Vitamin C aids in iron absorption, but it does affect the brain directly. It is responsible for building the myelin sheath that allows the nerves to communicate. Vitamin C partakes in manufacturing neurotransmitters like dopamine and serotonin.
Vitamin D—Vitamin D is absorbed from both dietary sources and sunlight. Similar to vitamin C, vitamin D facilitates nerve growth. Experts claim vitamin D activates certain enzymes to produce neurotransmitters and reduce inflammation.
Vitamin E—Vitamin E is the main vitamin that combats neurodegeneration in the brain by reducing oxidative stress. When compounded with other vitamins, it improves memory and cognitive thinking processes.
Zinc—Deficiencies in zinc reflect issues with language and numbers. Patients with Alzheimer’s disease tend to have a zinc deficiency, which provides evidence that zinc aids in cognitive function.
Magnesium—Unrefined grains (i.e. buckwheat), green leafy vegetables, and nuts (i.e. almonds, cashews) are sources of magnesium. This deficiency is common in third-world countries and vegetarians.
Dietary Psychology: Can Your Diet Lower Your Risk of Dementia?
Dementia is an umbrella term for neurodegenerative illnesses that cause impaired cognitive skills. Those with dementia experience memory loss, confusion, difficulties with language, and problem-solving abilities that inhibit normal daily functioning. The most common form of dementia is Alzheimer’s disease.
Published in April 2020’s edition of American Academy of Neurology, people who primarily eat snack foods (i.e. cookies, cakes), processed meats, and starchy foods such as potatoes have a higher risk of dementia than individuals who consume foods from a diverse range of food groups. Additionally, previous studies confirm that greater caloric intake is associated with Alzheimer’s.
Abiding by dietary guidelines proposed by the Alzheimer’s Association is actually a treatment for the condition. Patients have an increase in memory and an overall reduction in the progression of the disease. Two diets are recommended to fight dementia:
DASH Diet—DASH stands for The Dietary Approaches to Stop Hypertension. It promotes a diet to lower blood pressure, which reduces stress on the nervous system. Someone following the DASH diet is encouraged to reduce their intake of excessive amounts of sodium, fats, red meats, full-fat dairy products, sweets, sugary beverages and to consume lean meats (i.e. poultry, fish), whole grains, nuts, fruits, and vegetables.
The Mediterranean Diet—The Mediterranean diet limits red meat, replaces butter with healthy alternatives and focuses on a diet of fruits, fresh vegetables, nuts, and whole grains. Fish and poultry are eaten twice weekly and spices replace salt.
Nutritional Psychology: Foods That Are Harmful To Your Brain
Much like a diet of fruits, green leafy vegetables, whole grains, lean meats, nuts, and seeds are healthy for the brain, there are many foods that have the opposite effect. The chemicals in the foods we eat are stored throughout the body, including the brain and nervous system.
Sugary soft drinks include high fructose corn syrup. High fructose corn syrup is 55 percent fructose and 45 percent glucose. The inflammatory substance incorporated into our favorite beverages is known to impair memory. For example, high fructose corn syrup affects brain function because of it leads to insulin resistance. When the body is unable to bring blood glucose levels to normal ranges, the increase levels are damaging to the brain.
Refined carbohydrates are processed grains like white flour. They have a high glycemic index in which the body responds with a spike in blood sugar levels. Studies of the elderly population proved that the risk of dementia and mild cognitive impairment is nearly doubled in the population who received over half of their dietary caloric intake from unhealthy carbohydrates. Whole, unrefined grains, fruits, and vegetables are healthier alternatives.
While naturally occurring trans fats in meat and dairy products are not dangerous in controlled amounts, hydrogenated vegetable oil, margarine, pre-packaged desserts, frosting, and shortening are foods hiding the brain’s silent killer. Synthetic trans fats are harmful to cognitive function, as well as cardiac health. It advances inflammation.
“Sugar free” is not always the healthier option. Aspartame and artificial sweeteners are in sugar free products. Aspartame is made from the amino acids aspartic acid and phenylalanine. If aspartame is consumed, the body breaks it down into methanol which is toxic in large amounts.
Studies show artificial sweeteners provoke behavioral changes, depression, and learning difficulties. Participants consumed 11 mg of aspartame for every pound of body weight. After eight days, they scored lower on cognitive tests, were irritable, and had increased rates of depression in comparison to control subjects.
Alcohol impairs the way in which the brain communicates and decreases brain volume. Those who frequently consume alcohol typically develop a B vitamin deficiency, which is connected to poor cognitive transparent pharmacy functioning. While the majority of detrimental effects stem from episodes of binge drinking, it is recommended that young people avid alcohol because it interferes with brain development. Teenagers who drink are susceptible to risky behaviors and alcohol dependence into adulthood.
Nutritional Psychology: Which Diet Is Best For Your Brain?
So, what diet is best for your brain? Low carb, high carb, high fat, low fat, calorie restriction? Optimal eating habits are not any single diet. It is learning to be intuitive with your body’s nutritional needs, consuming a diet as colorful as the rainbow, and incorporating a variety of foods from all food groups. It is about establishing a balance that allows your body and brain to thrive.

How you combine them may raise dementia risk: Study finds ‘food networks’ centered on processed meats, starches may raise risk. ScienceDaily.

The brain is a powerful and vital organ that is essential to being alive. With that said, it would not hurt to have knowledge of the main parts of the brain and their functions. Basically, the brain has 3 parts: the cerebrum, the cerebellum, and the brain stem. Each of these parts provides different functions for the brain, and we cannot survive without them.
Also known as the cortex, the Cerebrum is by far the largest portion of the brain and weighs about two pounds. For the record, the entire brain weighs three pounds. The cerebrum is home to billions and billions of neurons. These neurons control virtually everything we do. It controls our movements, thoughts and even our senses. Since the cerebrum has so many functions, if it’s damaged, there are many different consequences.
The cerebrum consists of four different lobes that control all of our movements. The four lobes include: the frontal lobe, parietal lobe, temporal lobe, and the occipital lobe.
The Frontal Lobe
The biggest lobe in the cortex. It is located in the front, right behind the forehead. It extends from the anterior to the central sulcus. It is the control center of your brain. The frontal lobe is involved in planning, reasoning, problem solving, judgement, and impulse control, as well as in the regulation of emotions, like empathy, generosity, and behavior. It is linked to executive functions.
The Parietal Lobe
It’s located between the central sulcus and the parietal-occipital sulcus. This part of the brain helps to process pain and tactile sensation. It is also involved in cognition.
The Temporal Lobe
It is separated from the frontal and parietal lobe by the lateral sulcus and the limits of the Occipital lobe. It is used in auditory and language processing and is also used in memory functions and managing emotions.
The Occipital Lobe
It is delimited by the posterior limits of the parietal and temporal lobes. It is involved in visual sensation and processing. It processes and interprets everything that we see. The Occipital lobe analyzes aspects like shape, color, and movement to interpret and make conclusions about visual images.
Finally, the cerebrum consists of two layers: the cerebral cortex, which controls our coordination and personality, and the white matter of the brain, which allows the brain to communicate.
The Cerebral Cortex
A thin layer of gray matter that grooves around itself, forming a type of protuberance, called convolutions, that give the characteristic wrinkled look to the brain. The convolutions are delimited by grooves or cerebral sulci and those that are especially are deep are called fissures.
The cortex is divided into two hemispheres, right and left, and they are separated by the interhemispheric fissure and joined by a structure called the corpus callosum which allows transmission between the two. Each hemisphere controls a side of the body, but this control is inversed: the left hemisphere controls the right side, and the right hemisphere controls the left side. This phenomenon is called brain lateralization.
White matter is the subway of the brain. It connects the different parts of gray matter in the cerebrum to another. Like a subway/metro, this type of matter remains underneath it all (the surface in life, gray matter in the brain) and this underneath part is filled with different passages, links, and paths to take- each one with a different destination and purpose.
It’s known to be white because this type of matter is myelin rich. Myelin is a fatty-rich substance that causes the matter to appear white. In reality, the matter is a pinkish-white. In adults, the matter is about 1.7-3.6% blood and takes up about 60% of the brain!
The Limbic System:
Your limbic system functions range from regulating your emotions to storing your memories to even helping you to learn new information. Your limbic system is one of the most essential parts of the brain that help you live your daily life. The primary structures that work together in your limbic system are the amygdala, the hippocampus, the thalamus and hypothalamus, the cingulate gyrus, and the basal ganglia. All these parts help you to be active in society, engage in social relationships, and be a well-rounded person. To learn more about the interesting ways your limbic system impacts your life, sit back and get in-tuned with all of its hard-working employees!
Shaped like a small almond, the amygdala is located in each of the left and right temporal lobes. It’s known as “the emotional center of the brain,” because it is involved in evaluating the emotional intake of different situations or emotional intelligence (for example, when you feel happy because you received an awesome grade on your math exam or when you might be frustrated because the heavy traffic is making you late for work).
The amygdala is what makes the brain recognize potential threats (like if you are hiking in the lone woods and suddenly you hear the loud footsteps of a bear coming toward you). It helps your body prepare for fight-or-flight reactions by increasing your heart and breathing rate. The amygdala is also responsible for understanding rewards or punishments, a psychological concept known as reinforcement coined by the classical and operant conditioning experiments of Ivan Pavlov.
The Hippocampus is a small subcortical seahorse shaped structure that plays an especially important role in the formation of memory, both in classification and long-term memory. Among its main functions are the mental processes related to memory consolidation and the learning process. As well as processes associated with the regulation and production of emotional states and spatial perception.
It is similar to the re-transmission station of the brain: it transmits the majority of perceived sensory information (auditory, visual, and tactile), and allows them to be processed in other parts of the brain. It is also used in motor control.
It is a gland located in the center area of the base of the brain that has an especially important role in the regulation of emotions and many other corporal functions like appetite, thirst, and sleep. The functions of the Hypothalamus are essential to our daily life. It is responsible for maintaining the body’s systems, including body temperature, body weight, sleep, mating, levels of aggression and even emotional regulation. Most of these functions are regulated by a chain of hormones that inhibit or release between themselves.
The Cingulate Gyrus
This part is located in the middle of your brain next to the corpus callosum. Not much is known about the cingulate gyrus, but researchers suggest that this is the area that links smell and sight with pleasurable memories of previous experiences and emotions because it provides a pathway from the thalamus to the hippocampus. This area is involved with your emotional reaction to pain and how well you regulate aggressive behavior.
The Basal Ganglia
This area is an entire system within itself located deep in the frontal lobes. It organizes motor behavior by controlling your physical movements and inhibiting your potential movements until it gets the instructions to carry them out, based on the circumstances that you are in. The basal ganglia also participate in rule-based habit learning; choosing from a list of potential actions; stopping yourself from undesired movements and permitting acceptable ones; sequencing; motor planning; prediction of future movements; working memory; and attention. It is made up of a few structures, such as:
The Caudate Nucleus
The caudate nucleus sends messages to your frontal lobe, specifically to your orbital cortex (just above the eyes) which alerts you that something is not quite right with the physical situation you are in (usually during tense or anxious moments), so you should take action to fix your uneasiness.
The putamen lies directly underneath the caudate and controls your coordinated automatic behaviors, like riding a bike, driving a car, working on an assembly line, and any other task that doesn’t really involve upper-level thinking.
The Nucleus Accumbens
The nucleus accumbens is a brain part involved in functions such as motivation, reward, or positive behavioral reinforcement. The role of nucleus accumbens is to integrate motivation along with the motor action. Its function is to transfer relevant motivational information to the motor cells in order to obtain a certain reward or satisfaction. An imbalance is related to many psychiatric and neurological disorders such as depression, obsessive-compulsive disorder, bipolar disorder, anxiety disorders, Parkinson’s disease, Huntington’s disorder, obesity and drug abuse.
From Latin, meaning “little brain,” the cerebellum is a two-hemisphere structure located just below the rear part of the cerebrum, right behind the brain stem. Representing about 11 percent of the brain’s weight, it is a deeply folded and highly organized structure containing more neurons than all of the rest of the brain put together. The surface area of the entire cerebellum is about the same as that of one of the cerebral hemispheres.
The cerebellum is the second largest part of the brain, and it plays a significant role for our motor skills. It is located at the base of the brain, and damage to it can lead to decline in your motor skills. Besides motor control, the cerebellum has other different functions. One function that it has is to maintain our balance and posture. Another major function of the cerebellum is that it helps control the timing and force of various muscles.
Motor learning is another function of the cerebellum, and it has the biggest impact on skills that require trial and error. Even though it is mostly associated with motor control, the cerebellum has some control of our cognitive functions, such as language.
The Brain Stem:
Even though the brainstem is small, it controls many important functions in our bodies. Some functions of the brainstem include breathing, arousal, awareness, blood pressure, heart rate and digestion. It also controls our sleep patterns, body temperature, heart rhythms and even our hunger and thirst. In addition, it regulates the central nervous system.
The brain stem is the oldest and deepest area of the brain. It is often referred to as the reptilian brain because it resembles the entire brain of a reptile. The brainstem is also the smallest part of the brain and sits beneath your cerebrum in front of your cerebellum—and it connects the cerebrum to the spinal cord. Parts of the brainstem include: the midbrain, medulla oblongata and the pons.
It is the structure that joins the posterior and anterior brain, driving motor and sensory impulses. Its proper functioning is a pre-requisite for the conscious experience. Damages to this part of the brain are responsible for some movement problems, like tremors, stiffness, strange movements, etc.
The Medulla Oblongata
It helps control our automatic functions, like breathing, blood pressure, heart rate, digestion, etc.
The Pons, also known as the Annular Protuberance, is the portion of the base of the encephalon that is located between the medulla oblongata and midbrain. It connects the spinal cord and the medulla oblongata to the superior structures in the hemispheres of the cerebral cortex and/or the cerebellum. It is used in controlling the brain’s automatic functions and it has an important role in the awake-state levels and consciousness and sleep regulation.
The Spinal Cord:
The Spinal Cord is a long, whitish cord that is located in the vertebral canal and connects the encephalon to the rest of the body. It acts as a type of information highway between the encephalon and the body, transmitting all of the information provided by the brain to the rest of the body.
THE CENTRAL NERVOUS SYSTEM: NERVES, NEURONS, & NEUROTRANSMITTERS
Have you ever stopped to think about how the Nervous System works? How is your body organized? How does it really work? What structures make up the Nervous System? We are full of tracks that come and go loaded with data, electrical currents, chemicals, etc. at different rates and for different purposes.
12 pairs of cranial nerves enable us to perform our daily routine in a comfortable and efficient way, as they take part of the information of our senses to the brain and the brain to some of our muscles and viscera. Here is a small guide to know a little more about what are the cranial nerves, their anatomy, their classification, and their function.
As shown in the image above, the 12 pairs of cranial nerves have an associated Roman numeral. These numbers range from 1 to 12 corresponding in each case to the pair in question.
Each cranial nerve has a specific function. The next image shows how this person’s head is portrayed through numbers according to the cranial nerve functions. Would you dare to say what function each cranial pair has according to its number in the drawing?
Before starting, it’s important to point out the order that this explanation will have will be according to the corresponding Roman number assigned to the cranial nerve.
The Olfactory Nerve (I)
It’s the first of the 12 pairs of cranial nerves. It’s a sensory nerve, in charge of transmitting olfactory stimuli from the nose to the brain. Its actual origin is given by the cells of the olfactory bulb. It is the shortest cranial pair of all.
The Optic Nerve (II)
This cranial pair is the second of the 12 pairs of cranial nerves and it is responsible for conducting visual stimuli from the eye to the brain. It is made of axons from the ganglion cells of the retina, that take the information of the photoreceptors to the brain, where later it will be integrated and interpreted. It emerges in the diencephalon.
The Oculomotor Nerve (III)
This cranial nerve is also known as the common ocular motor nerve. It is the third of the 12 pairs of cranial nerves. It controls eye movement and is also responsible for pupil size. It originates in the midbrain.
The Trochlear Nerve (IV)
This nerve has a motor and somatic functions that are connected to the superior oblique muscle of the eye, being able to make the eyeballs move and rotate. Its nucleus also originates in the mesencephalon as well as the oculomotor nerve. It is the fourth of the 12 pairs of cranial nerves.
The Trigeminal Nerve (V)
It is a mixed cranial nerve (sensitive, sensory and motor), being the largest of all cranial nerves, it is the fifth of the 12 pairs of cranial nerves. Its function is to carry sensitive information to the face, to convey information for the chewing process. The sensory fibers convey sensations of touch, pain, and temperature from the front of the head including the mouth and also from the meninges.
The Abducent Nerve (VI)
It is also known as the external ocular motor cranial nerve and it is the sixth of the 12 pairs of cranial nerves. It is a cranial motor pair, responsible for transmitting the motor stimuli to the external rectus muscle of the eye and therefore allowing the eye to move to the opposite side from where we have the nose.
The Facial or Intermediate Nerves (VII)
This is another mixed cranial pair since it consists of several nerve fibers that perform different functions, like ordering the muscles of the face to create facial expressions and also send signals to the salivary and lacrimal glands. On the other hand, it collects taste information through the tongue. It is the seventh of the 12 pairs of cranial nerves.
The Vestibulo-Cochlear Nerve (VIII)
It is a sensory cranial nerve. It is also known as the auditory and vestibular nerve, thus forming vestibulocochlear. He is responsible for balance and orientation in space and auditory function. It is the eighth of the 12 pairs of cranial nerves.
The Glossopharyngeal Nerve (IX)
It is a nerve whose influence lies in the tongue and pharynx. It collects information from the taste buds (tongue) and sensory information from the pharynx. It leads orders to the salivary gland and various neck muscles that help with swallowing. It also monitors blood pressure. It is the ninth of the 12 pairs of cranial nerves.
The Vagus Nerve (X)
This nerve is also known as pneumogastric. It emerges from the medulla oblongata and supplies nerves to the pharynx, esophagus, larynx, trachea, bronchi, heart, stomach and liver. Like the previous nerve, it influences the action of swallowing but also in sending and transmitting signals to our autonomous system, to help the regulate activation and control stress levels or send signals directly to our sympathetic system. It is the tenth of the 12 pairs of cranial nerves.
The Accessory Nerve (XI)
This cranial pair is named the spinal nerve. It is a motor nerve and could be understood as one of the “purest”. It governs movements of the head and shoulders by supplying the sternocleidomastoid and trapezius muscles in the (anterior and posterior) regions of the neck. The spinal nerve also allows us to throw our heads back. Thus, we would say that it intervenes in the movements of the head and the shoulders. It is the eleventh of the 12 pairs of cranial nerves.
The Hypoglossal Nerve (XII)
It is a motor nerve which, like the vagus and glossopharyngeal, is involved in tongue muscles, swallowing and speech. It is the twelfth of the 12 pairs of cranial nerves.
What are Nerves Made From:
Neurons are the building blocks of the central nervous system. A neuron’s primary role is to communicate information. It communicates via electrical impulses or using specific chemicals such as neurotransmitters (what are the different types of neurotransmitters?). The neuron has 3 distinct parts. The dendrites, the cell body and the axon. Each structure plays a specific role in ensuring neurons are able to send and receive signals and connect with other neurons.
The dendrites are connected to the cell body. They conduct messages from axon of other neurons and pass the message onto the cell body. The cell body sits between the dendrites and the axon. It determines the strength of the message it receives from the dendrites. If it is strong enough, it will send the message down the axon. The axon is connected to the cell body. It conducts the message from the cell body and passes it on to other neurons.
Dendrites are branch-like structures structures surrounding the cell body. They receive electrical and chemical messages from other neurons, which are collected in the cell body. These messages are either inhibitory or excitatory in nature. If the message is inhibitory, the cell body will not transmit the message to the axon. However, if the message is excitatory in nature, then the cell body will send the message down the axon and pass it to other neurons.
The Soma (or Cell Body)
Also known as the soma, the cell body is a ball-like structure. It contains the control center of the neuron, also known as the nucleus. Together, the cell body and the nucleus control the functions of the nerve cell. To be able to do this, the cell body contains organelles or really tiny organs in the nucleus.
Each organelle has a unique job. First and foremost, the most important organelle, the nucleus, regulates all cell functions. It also contains the cell’s DNA, which is essentially the neuron’s blueprint. The nucleus is another organelle that serves a vital purpose to the functioning of the neuron. It nucleolus produces ribosomes, which are essential to protein production. The cell body is also home to the endoplasmic reticulum, Golgi apparatus, and mitochondria. The mitochondria is the neuron’s fuel source, it produces all the energy needed for the nerve cell to function properly.
The endoplasmic reticulum and the Golgi apparatus, work together, with the rest of the organelles in the nucleus to produce and transport protein. The protein produced by the cell body, are the key ingredients, to build new dendrites. Building new dendrites enable the neuron to make new connections with other neurons. As well as making proteins, the cell body is also responsible for making chemicals, also known as neurotransmitters, which neurons use as signals. Neurotransmitters can serve and inhibitory or excitatory function to the neuron.
The axon is long and slender, and it projects electrical impulses away from the cell body. The axon communicates with other neurons. When the electrical or chemical message reaches the axon terminal (end of the axon), The axon terminal release neurotransmitters into the synapse (small junction between two neurons). The neuron uses the synapse to communicate and send messages to other nerve cells.
How Nerves Communicate:
A synapse is the space between two neurons which allows for neural communication, or synaptic transmission. Synapses are found throughout the body, not just located in the brain. They project onto muscles to allow muscle contraction, as well as enable a multitude of other functions that the nervous system covers.
As a synapse is the gap in between two neurons, we need to establish which neuron sends out the signals and which neuron receives those signals.
The Presynaptic Neuron
The presynaptic neuron is the neuron that initiates the signal. At many synapses in the body, presynaptic neurons are vesicles filled with neurotransmitters. When the presynaptic neuron is excited by an action potential, the electrical signal propagates along its axon towards the axon terminal. This excitation signals the vesicles in the presynaptic neuron, filled with neurotransmitters, to fuse with the membrane of the axon terminal. This fusion allows for the neurotransmitters to be dumped into the synaptic cleft.
The Postsynaptic Neuron
The postsynaptic neuron is the neuron that receives the signal. These signals are received by the neuron’s dendrites. When there are neurotransmitters present in the synapse, they travel across the gap in order to bind to receptors on the postsynaptic neuron. When a neurotransmitter binds to a receptor on the postsynaptic neuron’s dendrite, it can trigger an action potential. That action potential can then be propagated and influence further communication.
In the nervous system there are two main types of synapses: chemical synapses and electrical synapses. Thus far, for simplicity and understanding the basics of how a synapse functions only chemical synapses have been discussed. This poses the question: why does the nervous system need two types of synapses?
Chemical synapses are any type of synapse that uses neurotransmitters in order to conduct an impulse over the small gap in between the presynaptic and postsynaptic neurons. These types of synapses are not in physical contact with each other. Since the transmission of a signal depends on the release of chemicals, a signal can only flow in one direction. This direction is downward from presynaptic to the postsynaptic neuron.
As previously stated, these types of neurons are widely spread throughout the body. The chemicals released in these types of synapses ways excite the following neuron. The neurotransmitters can bind to the receptors on the postsynaptic neuron and have an inhibitory effect as well. When inhibition occurs, signal propagation is prevented from traveling to other neurons.
Chemical synapses are the most abundant type of synapse in the body. This is because various neurotransmitters and receptors are able to interpret signals in a large combination. For instance, a neurotransmitter and receptor combination may inhibit a signal on one postsynaptic neuron but excite a large amount of other postsynaptic neurons.
Chemical synapses allow for flexibility of signaling that makes it possible for humans to engage in high-level tasks. However, this flexibility comes at a cost. Chemical synapses have a delay due to the need for the neurotransmitter to diffuse across the synapse and bind to the postsynaptic neuron. This delay is very small but still is an important point when comparing the two types of synapses.
Electrical synapses are types of synapses that use electricity to conduct impulses from one neuron to the other. These synapses are in direct contact with each other through gap junctions. Gap junctions are low resistance bridges that make it possible for the continuation of an action potential to travel from a presynaptic neuron to a postsynaptic neuron. Due to their physical contact, electrical synapses are able to send signals in both directions, unlike chemical synapses. Their physical contact and the use of sole electricity make it possible for electrical synapses to work extremely fast.
Transmission is also simple and efficient at electrical synapses because the signal does not need to be converted. Another key difference between chemical and electrical synapses is that electrical synapses can only be excitatory. Being excitatory means that an electrical synapse can only increase a neuron’s probability of firing an action potential. As opposed to being inhibitory, which means that it decreases a neuron’s probability of firing an action potential. This can only be done by neurotransmitters. Despite being extremely fast, these types of excitatory signals cannot be carried over great lengths.
Electrical synapses are mainly concentrated in specialized brain areas where there is a need for very fast action. The best example of this is the large amount of electrical synapses in the retina, the part of the eye that receives light. Vision and visual perception are our dominant senses, and our eyes are constantly receiving visual sensory information. This information also runs on a feedback loop when we interact with our environment, which means that we receive information from our surroundings and immediately create an appropriate response to it. This is why it makes sense that electrical synapses are seen in a large concentration here. The fast action, multiple directions, and efficiently all allow for prime functionality.
How Nerves Communicate – Neurotransmitters:
You’ve probably heard of how dopamine plays a role in feelings of pleasure, or how serotonin levels influence depression. But neurotransmitters do so much more than make us feel happy or sad. Not only do they influence our mood, but they also influence how our hearts beat, how our lungs breathe, and how our stomachs digest the food we eat.
Neurotransmitters interact with receptors on the dendrites of the neuron, much like how a lock and key work. The neurotransmitters have specific shapes that fit into a receptor that can accommodate that shape. Once the neurotransmitter and the receptor are connected, the neurotransmitter sends information to the next neuron to either fire an action potential, or to inhibit firing. If the neuron gets the signal to fire, then the whole process starts over again along the chain of neurons.
Here are some of the most important neurotransmitters:
Dopamine plays many different roles in the brain, depending on the location. In the frontal cortex, dopamine acts as a traffic officer by controlling the flow of information to other areas of the brain. It also plays a role in attention, problem-solving, and memory. And you’ve probably heard how dopamine plays a role in things that give us pleasure. So, if you were to eat a piece of chocolate, dopamine would be released in some areas of the brain, allowing you to feel enjoyment, motivating you to eat more chocolate.
Serotonin is known as an inhibitory neurotransmitter, meaning that it doesn’t give the next neuron the signal to fire. Serotonin is involved with mood, as well as your sleep cycle, pain control, and digestion. In fact, the majority of serotonin in the body can be found in the gastrointestinal tract, and only about 10% is located in the brain. Aside from aiding in digestion, serotonin can also help with forming blood clots and increasing sex drive.
Acetylcholine (ACh) plays a major role in the formation of memories, verbal and logical reasoning, and concentration. ACh has also shown to help with synaptogenesis or the production of new and healthy synapses throughout the brain. Acetylcholine comes from the chemical known as choline, which can be found in foods such as eggs, seafood, and nuts.
Acetylcholine also plays a significant role in movement. A nerve cell can release ACh into a neuromuscular junction, which is a synaptic connection between a muscle fiber and a nerve cell. When ACh is released, it causes a series of mechanical and chemical reactions that result in the contraction of muscles. When there is a lack of ACh in the neuromuscular junction, the reactions stop, and the muscle relaxes.
GABA is also an inhibitory neurotransmitter that helps to balance any neurons that might be over-firing. This inhibitory ability becomes especially helpful when it comes to anxiety or fear because the release of GABA helps to calm you down. In fact, caffeine actually works to inhibit GABA from being released, so that there is more stimulation in the brain.
GABA also plays a role in vision and motor control. Some drugs work to increase the levels of GABA in the brain. This increase helps with epilepsy and helps to treat the trembling found in patients with Huntington’s disease.
These might sound like two big and confusing words because you’ve probably heard about adrenaline (epinephrine) before. Before we go any further, let’s define these terms. Another name for adrenaline is epinephrine. Epinephrine is a hormone that is secreted by the adrenal gland, which is a gland that rests on top of the kidneys. Hormones are molecules that are released into the bloodstream. Noradrenaline is also known as norepinephrine.
Norepinephrine is a neurotransmitter, meaning that it is used for interactions between neurons. Noradrenaline is an excitatory neurotransmitter that helps to activate the sympathetic nervous system, which is responsible for your “fight or flight” response to a stressor. Norepinephrine also plays a role in attention, emotion, sleeping and dreaming, and learning. When it is released into the bloodstreams, it helps to increase heart rate, release glucose energy stores, and increase blood flow to the muscles.

The human brain is an incredibly complex feat of nature. Capable of creating complex social structures, languages, culture, art, and science. Our brains allow us to explore and understand the universe better than any other animal on the planet ever has. But even with all of this knowledge, we are only just beginning to understand the human brain itself.
Types of Brain Scans & Imaging Tools:
Today we still do not have a clear-cut picture of the whole brain in itself. Not every network has been mapped, but we have moved forward a substantial amount. The development of non-invasive and invasive neuroimaging methods and their use for research and medical purposes was a definite breakthrough.
We have methods that can view the cortical areas of the brain. Other techniques look at cortical columns and different layers. We have methods that can record a single cell by itself. Going even further, we can look at the soma of the neuron, the dendrite and, separately the axons. We can even look at the synaptic connections between the two neurons.
Positron emission tomography (PET) scans are used to show which parts of the brain are active at a given moment. By injecting a tracer substance into the brain and detecting radioactive isotopes in the tracer, we can see what parts of the brain are actively using glucose, a sign of brain activity. As a specific brain region becomes active, it fills with blood, which delivers oxygen and glucose, providing fuel for that region.
These areas become visible in the PET scan, thanks to the tracer substance, and allow us to create images of which areas of the brain are active during a given activity. The PET scan can only locate generalized brain areas, not specific clusters of neurons. In addition, PET scans are considered invasive and costly to perform.
Computed tomography (CT) scans are used to create images of the brain by recording the levels of X-ray absorption. Subjects lay on a flat table, which is connected to a large cylindrical tube-shaped apparatus. Inside the tube is a ring that holds an X-ray emitter. As the X-ray emitter moves along the tube, sensors on the opposite side of the ring detect the amount of X-rays that pass through. Since different materials–such as skin, bone, water, or air–absorb X-rays at different rates, the CT scan can create a rough map of the features of the brain.
Magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI) scans are imaging tools used widely in the field of psychology. Using a strong magnetic field, MRIs create alignment within the nuclei of atoms within the tissues of the body and brain. By measuring the changes as the nuclei return to their base states, the MRI is able to create a picture of the brain’s structure.
As a non-invasive procedure, with little risk to health, MRI scans can be performed on a broad range of subjects, including infants, the elderly, or pregnant mothers. Because of this, they can also be used multiple times on a single individual to map changes over time. The main difference between MRI and fMRI is that while basic MRI scans are used to image the structure of the brain, fMRI are used to map our the activity within the brain structures.
An upgrade from the MRI – Functional Magnetic Resonance Imaging detects the blood-oxygen-level dependent contrast imaging (BOLD) levels in the brain which are the changes in the blood flow and it not only gives the anatomical structures but the functions as well. Various colors will change depending on which part of the brain is active.
The big drawback with this technique is the fact that it does not directly measure brain activity, but BOLD signal so we cannot for sure say that the activity that we find via fMRI studies is fully accurate and is produced by neurons.
Diffusion Tensor Imaging, a technique based on MRI and it measures the way the water can travel through the white matter in the brain. It can show the activity as the colored area on the image. It’s particularly good in detecting concussions so can be used in clinical applications which is a huge advantage. Again, it does not measure direct brain activity which is a huge disadvantage and sometimes it also distorts the images. DTI has a quite low spatial resolution.
Electroencephalography (EEG) allows us to measure brain activity by placing electrodes on the scalp of a subject which sense electrical activity. EEG scans are non-invasive and allow researchers to record changes in brain activity down to the millisecond, making it one of the best options for understanding changes in the brain as they occur.
Magnetoencephalography (MEG) is a method of imaging the electrical activity in the brain through the use of magnetic fields. Extremely sensitive devices known as SQUIDs capture the activity in the brain, allowing researchers, doctors, or other professionals to understand which areas of the brain are responsible for various brain functions, or to determine the location of a pathology.
Near-infrared spectroscopy is a brain imaging technique that uses infrared light to measure oxygen levels in the brain. By shooting infrared light through the skull and measuring the light on the other side, NIRS scans can detect brain activity in a non-invasive, though indirect, way.
The electric field that TMS, or Transcranial Magnetic Stimulation, is able to generate is able to interfere with the action potentials that are happening in the brain. It’s a highly invasive technique and is able to be used in research applications for the workings of many diseases and pathologies. What we do know is that repetitive TMS is able to produce seizures so, obviously, it has some sort of side effects and needs to be used with caution.
Learn more about how doctors and researchers see our brains:
Once upon a time, researchers and scientist theorized that the brain stops developing within the first few years of life. The connections the brain makes during the ‘critical period’ are fixed for life. However, there is mounting evidence, from human and animal studies, that this view underestimates the brain. The brain has a remarkable ability to continually make new connections throughout our life, it has an extraordinary ability to compensate for injury and disease by ‘rewiring’ itself. Neuroplasticity, or brain plasticity, refers to this ability to form new connections, reorganize already established neural networks and compensate for injury and disease.
There are many types of brain plasticity. Positive brain plasticity, which enhances healthy functioning of the brain. Negative brain plasticity, which promotes unhealthy functioning of the brain. Synaptic plasticity occurs between neurons, whereas non-synaptic plasticity occurs within the neuron. Developmental plasticity occurs during early life and is important for developing our ability to function. Injury induced plasticity is the brain’s way of adapting to trauma.
Positive brain plasticity involves changes to structures and functions of the brain, which results in beneficial outcomes. For example, improving the efficiency of neural networks responsible for higher cognitive functions such as attention, memory, mood.
There are many ways in which we can promote neuroplastic change. Positive brain plasticity is when the brain becomes more efficient and organized. For example, if we repeatedly practice our times tables, eventually, the connections between different parts of the brain become stronger. We make less errors and can recite them faster.
Cognitive Behavioral Therapy, meditation, and mindfulness can all promote brain plasticity. These practices improve neural function, strengthen connections between neurons.
Negative Brain Plasticity
Negative brain plasticity causes changes to the neural connections in the brain, which can be harmful to us. For example, negative thoughts can promote neural changes and connections associated with conditions such as depression, and anxiety. Also overuse of drugs and alcohol enhances negative plasticity by rewiring our reward system and memories.
Synaptic plasticity is the basis for learning and memory. Furthermore, it also alters the number of receptors on each synapse (synapses are the connections between neurons that transmit chemical messages). When we learn new information and skills, these ‘connections’ get stronger. There are two types of synaptic plasticity, short-term and long-term. Both types can go in two different directions, enhancement/excitation, and depression. Enhancement strengthens the connection, whereas depression weakens it.
Short-term synaptic plasticity usually lasts tens of milliseconds. Short-term excitation is a result of an increased level of certain types of neurotransmitters available at the synapse. Whereas short-term depression is a result of a decreased level of neurotransmitters, long-term synaptic plasticity lasts for hours.
Long-term excitation strengthens synaptic connections, whereas long-term depression weakens these connections. As synaptic plasticity is responsible for our learning ability, information retention, forming and maintaining neural connections, when this process goes wrong, it can have negative consequences. For example, synaptic plasticity plays a key role in addiction. Drugs hi-jack the synaptic plasticity mechanisms by creating long-lasting memories of the drug experience.
This type of plasticity occurs away from the synapse. Non-synaptic plasticity makes changes to the way in which the structures in the axon and cell body carry out their functions. The mechanisms of this types of plasticity are not yet well understood.
In the first few years of life, our brains change rapidly. This is also known as developmental plasticity. Although it is most prominent during our formative years, it occurs throughout our lives. Developmental plasticity means our neural connections are constantly undergoing change in response to our childhood experiences and our environment. Our processing of sensory information informs the neural changes. Synaptogenesis, synaptic pruning, neural migration, and myelination are the main processes through which development plasticity occurs.
Rapid expansion in formation of synapses so that the brain can successfully process the high volume of incoming sensory stimuli. This process is controlled by our genetics.
Reduction of synaptic connections to enable the brain to function more efficiently. Essentially, connections that aren’t used or aren’t efficient are ‘pruned’ or ‘disconnected’.
this process occurs whilst we are still in the womb. Between 8 and 29 weeks of gestation, neurons ‘migrate’ to different parts of the brain.
This process starts during fetal development and continues until adolescence. Myelination is when neurons are protected and insulated a myelin sheath. Myelination improves the transmission of messages down the neuron’s axon.
Following injury, the brain has demonstrated the extraordinary ability to take over a given function that the damaged part of the brain was responsible for. This ability has been noted in many case studies of brain injury and brain abnormalities. Some stroke sufferers have displayed remarkable feats of recovering functions lost due to brain damage.
You may have heard at some point in your life that you cannot grow new brain cells. You may have been taught that from the moment you are born to when you die you can only lose brain cells. It is believed that this is due to hits to the head, consuming alcohol and narcotics, and from lack of cognitive stimulation. Well do not despair because your brain is not in danger, you can in fact “grow” new brain cells in a process called neurogenesis.
Scientists at Carnegie Mellon University‘s Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury.
When one brain area loses functionality, a “back-up” team of secondary brain parts immediately activates, replacing not only the unavailable area but also its confederates (connected areas), the research shows.
The research found that as the brain function in the Wernicke area decreased following the application of rTMS (transcranial magnetic stimulation), a “back-up” team of secondary brain areas immediately became activated and coordinated, allowing the individual’s thought process to continue with no decrease in comprehension performance.
The Brain-Body Connection:
The human brain is a marvel of evolution, capable of creating breathtaking works of art and music, developing complex systems of culture, language, and society, and uncovering mysteries of the universe through science, technology, and mathematics. But even a healthy brain couldn’t do any of these things without a healthy body to support it.
Anyone who has had to perform on stage or give a speech in front of a large group of people knows that the stress and anxiety, supposedly mental phenomenon, can manifest in physical discomforts such as “Butterflies” in our stomachs, sweaty palms, and increased heart rate.
Similarly, when we find ourselves receiving praise or affection, the feelings of happiness and euphoria we experience are readily apparent when our cheeks blush, our eyes dilate, and in extreme cases, we can even begin to cry from joy.
By taking care of our bodies, we can help to ensure our brains are functioning at their best. Although there is no single exercise or diet that is right for everyone – each person should speak to their nutrition or health professional to understand the best regimen for themselves – there are specific general rules of thumb for exercise and diet that can help just about anyone improve their brain health.
Every person thinks and acts a little differently than the other 7 billion on the planet. Scientists now say that variations in brain connections account for much of this individuality, and they’ve narrowed it down to a few specific regions of the brain. This might help us better understand the evolution of the human brain as well as its development in individuals.
Each human brain has a unique connectome – the network of neural pathways that tie all of its parts together. Like a fingerprint, every person’s connectome is unique. Researchers found very little variation in the areas of the participants’ brains responsible for basic senses and motor skills.
The real variety arose in the parts of the brain associated with personality, like the frontoparietal lobe. This multipurpose area in the brain curates sensory data into complex thoughts, feelings or actions and allows us to interpret the things we sense.
Brain Differences Based on Gender
There are some differences found in the brains of males and females, however it’s important to note that factors influencing brain development in both males and females include, not only biology, but also the environment. We must keep in mind that culture, and social constructions have an important role in how our brains develop.
In 1989, the National Institute of Mental Health (NIMH) initiated a large-scale longitudinal study of typical brain development, which to date has acquired data regarding brain development and function from over 1000 children (including twins and siblings) scanned 1-7 times at approximately two-year intervals. This study has provided much of the information we know today about the differences between the developing male and female brain.
Studies utilizing this data have found that the peak brain size in females occurs around 10.5 years, while the peak occurs around 14.5 years in males. The other areas most frequently reported as being different are the hippocampus and amygdala, with the larger size or more rapid growth of the hippocampus is typically reported in females, and the amygdala is larger or grows more rapidly in males. The hippocampus controls emotion, memory, and the autonomic nervous system, and the amygdala is responsible for instinctual reactions including fear and aggressive behavior. Because of the larger hippocampus, girls and women tend to input or absorb more sensory and emotive information than males do.
Brain Differences Based on Handedness
The brain has two hemispheres, that each specialize to govern specific tasks. The right hemisphere of the brain controls the left side of the body and is associated with mainly spatial perception tasks, face recognition, and understanding music. The left hemisphere controls the right side of the body and is associated with more computational tasks such as math and logic. The specialization of each side of the brain is important because it allows for maximizing neural processing.
Handedness can correlate to what function each hemisphere specializes in, which allows the brain to be almost anatomically symmetrical, but functionally asymmetrical. Functional asymmetry, or lateralization, allows for each hemisphere to work in tandem when processing the world around us.
Brain Differences Based on Age
We often forget we were once teenagers ourselves. Their angst, impulsivity, and the crazy desire to live for fun makes them seem as if they are from another world. These characteristics are due to the teenage brain. The teenage brain undergoes a series of changes during cognitive development and is easily influenced by a number of factors. Physically, an adult and a teenager are near the same size.
But when it comes to the brain, there are vast differences. The teenage brain relies on the amygdala. The amygdala is reactive, stimulating a strong emotional response. When making decisions and problem solving, a teenager relies mainly on emotions. An adult’s cognitive processes are carried out using the developed prefrontal cortex—the area of the brain that causes us to think prior to behaving. Thoughts and decisions of an adult are less reactive and more logical and rational.

Consuming drugs affects the brain’s limbic system. This brain structure is in charge of awarding the satisfaction of our vital needs with a pleasant sensation or pleasure (when we are hungry and we eat, we feel pleasure). When we consume drugs, we feel a similar sensation based off of artificial pleasure, which is what leads to the start of a drug addiction.
Drugs happen to be chemical substances and they are able to affect the brain in various ways. They usually do so by interfering with how neurons communicate with one another. They can either enhance or diminish the sending, receiving and processing information functions. In the normal functioning after the neuron sends the information onto the next neuron and the neurotransmitters or chemical messengers are not needed website anymore, they are re-uptaked back or ‘cleaned’ up. Some drugs will block this re-uptake, therefore, leaving an enormous amount of these neurotransmitters in the synaptic cleft which causes the message to be enhanced and disrupts further communication. Amphetamine and cocaine do that.
Other drugs like heroin and marijuana are able to mimic a neurotransmitter by attaching themselves to the post-synaptic receptors. Therefore, they can activate other neurons but not in the same way as a neurotransmitter would. Because of that, they will send different messages along the pathways of the network, therefore, altering its normal functioning.
How Drugs Affect the Brain
When people use drugs continuously for a very long period of time their brain becomes used to this much amount of dopamine. The brain will start to compensate by naturally either making a smaller amount of dopamine and decreasing the receptors where dopamine binds in an attempt to regulate things back into homeostasis. Dopamine will therefore not be able to produce as much pleasure anymore, for any activities. That’s why it’s so difficult for a person who abuses drugs to get back into normal life – the pleasure they used to feel from regular activities diminishes.
How Cocaine Affects the Brain
Although there are many neurotransmitters, dopamine and GABA are the two altered from cocaine use. The neurotransmitter, dopamine, oversees the body’s pleasure and reward system. Cocaine acts on dopamine by signaling a sudden release of dopamine in the area between neurons (synapses) and tricking the brain’s pleasure response. The abundance of dopamine is why users feel euphoria upon exposure. Normally a second neurotransmitter known as GABA counteracts the raised dopamine levels. However, the process is unsuccessful because cocaine blocks its release. Continual use of cocaine overwhelms the nervous system. Eventually, neurons in the brain can no longer communicate when the drug induces a rush of dopamine. The dopamine receptors are damaged.
How Marijuana Affects the Brain
The endocannabinoid system is a biological system to maintain homeostasis. For the body to function properly, its conditions require balance. The heart rate must be within normal limits, temperature cannot be too hot or cold, and more. Cells in the body naturally produce endocannabinoids, which communicate with the nervous system and perform this role. Endocannabinoids attach to cannabinoid receptors on the surface of cells and are eventually destroyed by metabolic enzymes.
Marijuana, however, interferes with the endocannabinoid system. Cannabinoids from marijuana like THC bind to cannabinoid receptors, overloading the system and preventing naturally produced endocannabinoids from their regular tasks. The reward system consists of a series of brain structures from the ventral tegmental area to the hypothalamus that mediates reward. Neurons in these brain areas release dopamine upon pleasurable behaviors such as food or sex. Marijuana acts on the brain’s reward system.
As the THC attaches to cannabinoid receptors, the reward system is activated, and the user no longer responds as strongly to other pleasurable experiences. This is evidence of the addictive nature of marijuana. Scientists have taken a recent interest in how marijuana interacts with the brain’s reward system. Published in the journal, Human Brain Mapping, long-term marijuana users had more activity in the reward system on magnetic resonance imaging when shown marijuana related objects than non-users, and they had a reduction of brain stimulation when given alternative cues like their favorite fruit.
How Prescription Stimulant Use Affects the Brain
Scientists have discovered college-aged individuals who occasionally use stimulant drugs, such as cocaine, amphetamines and prescription drugs such as Adderall, display brain changes that may put them at higher risk for developing a serious addiction later in life.
A study from the University of California, San Diego School of Medicine, published in the Journal of Neuroscience, showed that occasional users have slightly faster reaction times, suggesting a tendency toward impulsivity. The most striking difference, however, occurred during the “stop” trials. Here, the occasional users made more mistakes, and their performance worsened, relative to the control group, as the task became harder. The brain images of the occasional users showed consistent patterns of diminished neuronal activity in the parts of the brain associated with anticipatory functioning and updating anticipation based on past trials.

Relative to size, human brains are much bigger than other mammals. In fact, our brains are over three times bigger than mammal’s brains similar in size. As you can imagine, there is no correlations between the animals’ absolute brain sizes and cognitive abilities. Cows, for example, have larger brains than just about any species of monkey, but unless they are very, very good at hiding it, cows are almost certainly less cognitively capable than most, if not all, “lesser-brained” primates.
The Human Brain is Inverted:
The right side of the brain interacts with the left side of our bodies, and the left side of the braininteracts with the right side of our bodies. Both sides of the brain have specific functions, but sometimes the two sides of the brain interact and work together. The right brain focuses on the expression and reading of emotions, understanding metaphors, and reading faces while the left brain is far more logical, focusing on language skills, analytical time sequence processing and skilled movement.
Size Doesn’t Always Mean Power:
Having a bigger brain does not mean you are more intelligent. Clearly, there is more to intelligence than brain size, or Albert Einstein, one of the smartest people who ever lived, who had an average brain size, would have been out of luck! It is important to take into consideration how to actually define intelligence.
The Human Brain is Full of Fat:
The brain is composed nearly 60% by fat, because without it, we could not live. People who eat a diet low in omega 3 fatty acids are more likely to suffer accelerated wear and tear on the brain. The brain is regarded as the fattest organ in our entire bodies. It has the highest concentration of fat present in a single organ in a healthy human being.
The Electrical Activity Produced by The Brain Forms A Pattern of Brain Waves:
This electrical activity of the brain changes depending on the activity that is being done. For example, the brainwaves of a sleeping person are very different from the brainwaves of someone that is awake.
The Texture of The Brain Is Similar To Tofu:
Experts say our brain has a consistency similar to that of tofu or gelatin. Fatty tissues, blood vessels, and water found in the brain give it that same consistency.
The Brain Feels No Pain:
Since there are no pain receptors in the brain, it is incapable of feeling pain. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake, as we saw before.
Emotions Are Found in The Primitive Structure of Your Brain:
The limbic system is composed of a set of cerebral structures that are considered very primitive in evolutionary terms, being placed in the superior part of the brainstem, below the cortex. These structures are fundamentally involved in the development of many of our emotions and motivations, particularly those related to survival such as fear, anger, and emotions linked to sexual behavior.
Sleeping well improves memory? Who hasn’t had problems concentrating at work after a poor night’s sleep? In 2013, a study showed that this common complaint among those who slept poorly wasn’t subjective, but a true reality: People who don’t get the reparative sleep at night that they need and those who suffer from some type of insomnia show memory and concentration problems. So, is it true that sleeping well improves memory?
Illnesses that cause memory loss or memory problems like Alzheimer’s or schizophrenia tend to be accompanied by sleep disorders or insomnia. Scientists continue to argue about if sleep deprivation is related memory problems. What came first, the chicken or the egg?
Recovery sleep has turned into one of the main recommendations for maintaining and enjoying good memory. In the last few years, more and more people have begun to talk about the benefits that a good night’s sleep can offer us. Some of the conclusions of these studies have been:
1. Sleeping well improves concentration.
2. It can help you get better grades.
3. Sleeping well helps you be more creative.
4. It combats depression
5. It helps you maintain a healthy weight.
6. It facilitated the oxygenation of the cells because breathing slows down while we sleep.
7. It protects the heart.
8. Sleeping well strengthens the immune system
9. Increases life span.
There’s no doubt that a good rest is important, but we still don’t know the mechanisms behind this phenomenon. A few days ago, a team of researchers at Bristol’s Center for Synaptic Plasticity at the University of Bristol have brought to light new evidence about the mechanisms that explain why sleeping well improves memory. The basic research study provides new keys to understanding how and why we are able to learn while we sleep.
In the investigation, the team lead by Dr. Mellor saw how some of the brain activity patterns that were produced during the day repeat themselves faster at night. This repetition takes place in the hippocampus (the brain structure related to memory), which strengthens neural connections between active nerve cells, which is essential for consolidating new memories and skills. The study also looked at the repeated diurnal patterns of brain activity during sleep depended on the emotional state that the subject had while they were learning.
According to the investigators, this is very important and may have practical implications for the design. For example, new teaching strategies that keep the student’s emotional state in mind to facilitate learning and memory.
Hopefully, this study brings to light why there is a relationship between sleep and memory. Now it’s our turn to make sure we get a good night’s sleep.
Tips For Sleeping Better and Improving Memory
1. Exercise. You don’t need to spend all day at the gym, but doing some type of exercise, like walking or jogging for 20-30 minutes a day. With a little bit of exercise, we’ll fall asleep quicker and sleep better.
2. Keep a routine. It’s important to go to sleep and wake up at the same time each day.
3. Don’t overdo caffeinated beverages during the day. Try to avoid coffee and soda in the afternoon. Try some decaffeinated tea.
4. Drink less alcohol. Alcohol doesn’t help us sleep well. Even though it helps us fall asleep by depressing our nervous system, it also makes us wake up more at night. Summary: We sleep poorly.
5. Only use the bed for sleeping (or sex). We should try to avoid doing anything else in our beds, like reading, watching movies, playing on our phones or tablets… All of these things disturb our sleep patterns.

Would you prefer to watch TV or read a book? The vast majority would likely choose the first option as their preferred entertainment. However, my fellow Netflix watchers are about to be sorely disappointment. Binge watching your favorite series may not be as healthy for the brain. Documented research favors reading to watching television, as it encourages brain neuroplasticity, enhances cognitive skills, and even strengthens cardiac function which encourages blood flow to the brain.
Reading VS. Television: Brain Neuroplasticity
The human brain has over 80 billion brain cells called neurons. Neurons have dendrites, which are branches that leading to synapses that connect them to other neurons. With these specialized brain cells, the brain is able to communicate signals to the body. The area of the brain dedicated to reading is the cortex. As we learn new skills like reading, the connection between neurons become stronger. This is especially true for children. Brain imaging research shows exposure to reading and phonics encourage brain plasticity—growth and reorganization of vital neural networks in the brain.
Reading VS. Television: Sensory Processing
Sensory skills are skills involving the receiving of information. For example, vision, hearing, touch, smell, taste, and proprioception are sensory processing skills. Both watching television and reading are sensory experiences but differ greatly. Reading does not overload visual processing like the flashing colors of a television screen. Along with strengthening brain connection, reading is important for the somatosensory cortex, which is responsible for responding to sensory information such as movement and pain. Readers think about the events depicted in books. Thus, reading a book about riding a bike activates the same brain area as physically riding a bike. Books offer a multitude of experiences causing the reader to deeply contemplate and connect a story.
Reading VS. Television: Verbal Communication
There are many forms of communication: verbal, written, listening, visual, and non-verbal (i.e. gestures, signing, eye contact, etc.). Research correlates lower verbal test scores with increased hours spent watching television. The frontal lobes of individuals who watch television are thicker, which is associated with lower verbal reasoning.
This is because reading provides all aspects of communication that are not included in books. Through words, readers are exposed to verbal dialogue, writing, interpreting character gestures, and more. Television does not portray as many details. Reading goes further into depth about what characters think, feel, and how they react. Readers must concentrate to think about the themes of the book and make inferences about the material.
Reading VS. Television: Vocabulary and Language
Although television is made of mostly dialogue, reading develops vocabulary. The words written in books are, on average, twice as complex than words spoken through television characters. Reading forces a person to look at unknown words and interpret their meaning through context clues. The increased vocabulary is not only helpful for writing, but for expression in everyday conversation. Books provide repeated exposure to known words, which tests knowledge and understanding.
Even listening to a book via audio or read aloud has better results on vocabulary than watching television. However, experts have found that the effect television has on vocabulary is neutral. As long as the time spent reading is not sacrificed for television watching, it does not reduce vocabulary.
Reading VS. Television: Attention Span
Whether a series or a lengthy movie, television condenses a story. The scenes are rapidly changing with shifts in camera angles. The plot is broken up for advertisement breaks. Most people are preoccupied with other tasks simultaneously such as doing homework, browsing the computer, sending text messages, or are engaged in a craft. The act of watching television does not involve equal levels of thinking in comparison to reading.
Reading requires constant attention. When reading, readers are often engrossed in the story and are not completing other tasks at the same time. They can process the material at their own pace instead of attempting to keep up with rapidly changing television scenes.
Reading VS. Television: Emotional Intelligence
The term emotional intelligence describes the awareness and the ability to control emotions. Expert psychologist’s at York University and Emory University found that literary fiction is related to a greater capacity for empathy, as readers imagine what it would be like if they were in the character’s shoes.
During the process of reading, we are uncovering the emotions of various characters and predicting their actions in response to those emotions. This translates to interactions in daily life. Readers are more apt to understand the actions and intentions of others because they are trained to do so from character perspectives. Readers observe interactions between characters and compare them to their lives. It is a key aspect of functional relationships.
Reading VS. Television: Imagery
Can you recall a movie or television series that is better than the book in which it is based? Probably not. This is due to imagery. Reading is far superior to television as it pertains to imagery. Television provides complete visual and auditory images. There is little left to viewers to imagine. Reading, however, is up to the discretion of the individual. No two interpretation is identical. One reader’s vision may be entirely different than what another perceives.
Reading VS. Television: Memory
Memory, comprised of short-term, long-term, and working memory, is a cognitive process the brain relies on to store and retrieve information. The mind is a muscle and functions optimally with practice. Reading is an exercise for memory. It presents information that readers can go back and review as many times as necessary to form their conclusions, recall words and their meanings, and processing letters. It leads to enhanced memory for situations outside of written language like the working memory involved in memorizing a phone number to call a friend.
Cognitive skills such as memory decline with age. Reading is known to prevent cognitive decline with age, as well as that associated with the development of dementia. Studies report that avid readers have lower levels of beta-amyloid—a protein deficient in Alzheimer’s patients.
Reading VS. Television: Behavior
Evidence that excessive TV watching impacts behavior is obvious through studies with child subjects. Children and adolescents are impressionable. They learn by modeling those in their environment. This includes the television and media they are exposed to like the presence of risky behaviors (i.e. violence, sexual situations, etc.) depicted in their favorite television series. Studies prove the violent behavior persists into adulthood.
Similarly, reading also has an effect on behavior. Readers adopt characters’ experiences. For example, a study including 82 undergraduate college students reading stories about the 2008 presidential election had startling results! The students who read first-person stories were over twice as likely to vote simply because reading influenced their behavior.
Reading VS. Television: Stress Reduction
The hustle and bustle of life is stressful. Juggling work, school, health, and relationships can be overwhelming. When your brain is running one-hundred miles a minute, reading lessens stress by 68 percent. The act is a distraction from stressful events, allowing us to live in the world of characters. It is truly an escape from reality. The brain reroutes energy to concentrating on the story instead of fueling the harsh effects of stress on the body.
Reading VS. Television: Improves Cardiac Function
Just 6 minutes of reading has amazing benefits for physical functioning. As the body relaxes, the muscles are not as tense. In addition to relaxation, reading lowers heart rate and blood pressure. Cardiac function is connected to the brain. Poor heart health is frequently seen with higher cholesterol levels, which causes injury to the brain’s white matter. However, reading improves blood flow and circulation to the brain.
Does Genre Alter the Benefits?
Similar to how watching an educational television series has an opposite effect on the brain as a drama, different genres of books do change the effect reading has on the brain. A wide variety of genres is optimal, as it broadens the experiences readers submerse themselves into and that strengthens the brain’s neurons. For example, biographies tend to evoke effects on emotions, whereas classic literary fiction focuses on vocabulary and thrillers are an exciting distraction to shift perspective and to reduce stress. To receive all of the benefits of reading, pick books you enjoy!

When we think about famous psychologists, we often think of older men from long ago who did experiments with pigeons or who talked about peoples’ relationships with their mothers. But, like any scientific discipline, psychology is a continually evolving field full of dedicated clinicians, researchers, and academics who are searching for new truths to uncover and new ways to prove or disprove the beliefs we have held for so long.
One of the most exciting areas of modern psychologic research is in the field of memory and recall, and there are few psychologists more important to this field than Elizabeth Loftus.
Early Work on Memory & Recall
Dr. Loftus, who currently holds the position of affiliate professor of psychology and law at the University of Washington, has been at the forefront of research on human memory and recall for nearly 50 years, studying how memories are formed and how recall of these memories can be affected over time.
Her research in this area has led to a number of awards and honors, as well as a place as the highest-ranked female on the list of 100 most influential psychological researchers of the 20th century from the Review of General Psychology.
After receiving her Ph.D. from Stanford University in 1970, Loftus went on to begin her first academic appointment at the New School for Social Research in New York City, studying the semantic information in long-term memory.
Dr. Loftus quickly realized that research in memory and recall could have a much more significant social impact in other areas, and in 1973 accepted a position as an assistant professor at the University of Washington and began researching how memory affects real-world situations.
One of her earliest studies focused on understanding whether eyewitness memory can be altered after the fact by information supplied by outside sources. This study built on previous research which had established that memories were constructions created using past experiences and other external manipulations, and not entirely accurate representations of events. These early studies provided clues that the way in which questions are presented, including the wording of questions, can affect how a person recalls events.
Building on these findings, Elizabeth Loftus began looking at what other ways misinformation could be presented to a person, the effect this misinformation has on recall, and how this erroneous recall can have serious, real-world consequences. This research led to the development of the paradigm known as the Misinformation Effect.
The Misinformation Effect & Eyewitness Testimony
Through her research, Elizabeth Loftus has demonstrated the pliability of human memory and recall. She has shown how memories can be affected by exposure to incorrect information, leading questions, or any number of sources of false information.
The Misinformation Effect is an example of what is known as retroactive interference, a phenomenon where the information presented in the present or future can affect the ability of a person to retain previously learned information correctly. An example of retroactive interference is when you have a telephone number for a long time. When you switch to a new number, after memorizing the new number, it becomes much more difficult to remember the older number.
Her research, and that of her colleagues in the field of memory and recall, has changed our understanding of how memory works and how long-term memories are not fixed, unchanging ideas stored forever in a frozen state waiting to be remembered, but are, in fact, mental constructs based not only on what happened at the time, but what we have learned and experienced in the time since the event has passed.
Our memories are affected by what we learn from others who recount their versions, by the expectations of those who want to hear what we remember, and from our own mind filling in gaps in our memory with information we received after the fact.
How Elizabeth Loftus’ Work Continues to Impact the World
The Misinformation Effect has powerful and dangerous implications for many areas of society and has generated hundreds of additional studies exploring the phenomenon.
There is likely no area where memory and recall, and the ways in which the Misinformation Effect can alter those memories, play a more critical role than in the legal field in general, and in eyewitness testimony in particular.
Much of how our modern legal systems around the world function is based on the testimony of witnesses who experienced the events. The fact that trials and questioning can happen months or even years after the events occurred can leave witnesses open to significant alterations in how they recall the events. And the fact that there are multiple sides invested in specific outcomes, there is plenty of opportunity for incorrect or incomplete information to seep into the recollections of eyewitnesses, whether they intend to or not.
One way this misinformation can have an unintended effect is when the witness identifies a suspect. When presented with a series of photographs, or a lineup of individuals, an eyewitness may read body language and other subtle clues from the interviewer and select the response the questioner is hoping for. This is similar to Hanz, the horse that could do math. Though the horse could not actually do math, when asked to add two numbers, he would tap his hoof to count, stopping once he reached the correct answer. He did this by reacting to the expressions of the questioner, who would likely show signs of excitement as the horse got close to the correct answer.
In this same way, the eyewitness, who may only remember vague details such as the color of the clothes, the hairstyle, and other generic information, may look at the lineup of potential suspects and unconsciously select the person for whom they receive the strongest body-language reaction from the questioner.
Similarly, the way questions are presented in questioning can affect the recall of witnesses. For example, a neutrally-worded question such as “what was the person who robbed the store wearing that day?” will not get the same information as a leading question such as “Other witnesses have told us that the person robbing the store was wearing a red sweater and blue pants, is that what you remember?” The second of these questions is potentially providing incorrect information, which may lead the witness to misremember the events based on both the expectations of the questioner and the supposed recollections of other witnesses.
Dr. Elizabeth Loftus has spent her entire career studying the way memory and recall works and has been a crusader for ensuring the misinformation effect is understood within the legal community. Her research has changed what we know about memory and continues to play a role in understanding the complex systems humans use to understand and remember their world.
Time flies when you’re having fun…and seems to stand completely still while you’re waiting for your food to cook in the microwave. We know that (complex metaphysical theories aside) time always moves at the same speed. We can look at our watch and see that a minute lasts just as long when you’re out with your friends as it does when you’re sitting in a dull office meeting about the new rules for how to use the printer.
So why is it that our body clock tells time in wildly different ways depending on what we’re doing and how we are feeling?
This system—though controlled internally through the continuous production and breaking-down of proteins in our cells in 24-hour-long cycles—is highly reliant on external stimuli such as the light and dark cycles due to the rotation of the earth (which is why looking at the bright screen on your phone right before bed makes it so hard to sleep, because the light is causing your brain to mistakenly think it is morning and time to stay awake). This is the same system that tells nocturnal animals to go out at night and that tells sunflowers to change position throughout the day.
In addition to this internal clock responsible for synchronizing our body’s many systems and functions, our brain also is able to track time in the moment, allowing us to keep track of how much time has passed in a specific moment and to create mental estimates of temporal durations. For example, this tracking clock is what allows us to perform activities in a normal amount of time, it allows us to know whether the amount of time we have been waiting for something to happen is appropriate, and it is what is responsible for allowing us to estimate how quickly to react to something such as when waiting to catching a ball.
This clock processes time in a much different way than our circadian system. Dean Buonomano, associate professor of neurobiology and psychiatry at the David Geffen School of Medicine at UCLA and a member of the university’s Brain Research Institute believes that whenever the brain processes sensory information “it triggers a cascade of reactions between brain cells and their connections. Each reaction leaves a signature that enables the brain-cell network to encode time.”
Our brain’s clock for tracking and estimating the passage is a complex system which requires not only that we measure the time as it passes, but also that we are constantly recording the amount of time that has passed.
Why Does it Feel Like Sometimes Time Flies and Others it Seems to Stand Still?
Recent research published in the Journal of Neuroscience may explain what causes the sensation that time sometimes seems to go faster, and other times seems to drag on, and on, and on…
The study found that neurons in a part of the brain called the supramarginal gyrus (SMG) fire at specific intervals in response to external stimuli. When we are exposed to repeated stimuli that cause these neurons to continually fire over long periods of time the supramarginal gyrus becomes fatigued and the firing of neurons begins to slow down slightly. Because the other systems in our brain continue to fire at their normal speed, the relative change between the system that measures time and the other systems makes us experience time as moving more slowly.
How Did Researchers Study Our Perception of Time?
The researchers, Hayashi and Ivry, studied the brain activity of healthy human subjects using fMRI. While the brain activity study participants was being measured, the researchers gave them tasks involving comparing time intervals.
To begin with, the participants we shown a fixed-duration visual stimulus (a grey circle) 30 times in a row. After the patients viewed the repeated stimulus, they were then shown a test stimulus and asked to estimate the duration of the test stimulus.
The researchers found that when the initial stimulus was short, participants tended to overestimate the length of the test stimulus, whereas when the initial stimulus was longer, participants underestimated the length of time.
When viewing the brain activity of the subjects, the researchers found a strong correlation between how accurately a subject perceived time and the activity in the SMG region, as SMG activity decreased participant’s estimates became less accurate.
How Does This Finding Affect Our Understanding of How We Tell Time?
In the past, one prevailing idea was that a region of the brain called the striatum was responsible for nearly all of our body’s inner timekeeping duties. This new study, combined with others showing the importance of the hippocampus in determining and remembering long periods of time, are showing that we may actually use much more of our brain to keep track of time than previously thought.
