Brain connections contribute to our unique personalities.

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.
