A Picture of (Brain) Health: Powerful Brain Scans and Assessment Batteries We Use to Understand Our Most Complex Organ

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.

Scientists, biologists, and medical professionals are on a neverending quest to learn about the brain, and thanks to innovative brain scan technologies, we are closer than ever to unlocking the mysteries of how the brain works.

But why is it so difficult to understand how our brains function?

Brain Anatomy

The human brain is made up of billions of neurons, or brain cells, each connected in a web of synapses so dense there are more connections in a single human brain than there are stars in the observable universe.

If we zoom out a little and take a holistic view of the brain, we see that the neurons are grouped into three main parts: the brainstem, the cerebellum, and the cerebrum. Each of these parts plays a unique role in how our brains function and how we think, act, and perceive the world.

The Human Brain, in Three Parts:

Major Zones of the Cerebrum:

Each of the hemispheres of the Cerebrum is further divided into four distinct zones called lobes.

What Tools Do We Use To Understand the Human Brain?

Though we still have a long way to go to unlock all the secrets of the human brain, new technologies, methods, and tools such as brain scans allow us to understand more about the human brain than ever before.

Other Tools & Methods:

Though we have new tools and technology to aid us in understanding the human brain, that doesn’t mean that brain scans are the only tools we have at our disposal. Some of the best methods for understanding our brains don’t require any medical equipment at all.

As we continue to unlock new mysteries of the brain and create more and more powerful tools for exploring the human mind, we will continue to grow our ability to treat patients and improve the lives of people all over the world. Brain scans allow us to peak into one of the most complex systems we have ever seen. Still, it is essential to remember that it is the tool that gives us the answers, but the researchers and medical professional who interpret the results.
