Introversion and extroversion come from different wiring in the brain

I just recently realized that introversion and extroversion are not actually related to how outgoing or shy we are, but rather how our brains recharge.
Here’s how the brains of introverts and extroverts differ:

Research has actually found that there is a difference in the brains of extroverted and introverted people in terms of how we process rewards and how our genetic makeup differs. For extroverts, their brains respond more strongly when a gamble pays off. Part of this is simply genetic, but it’s partly the difference of their dopamine systems as well.
........................

The nucleus accumbens is part of the dopamine system, which affects how we learn, and is generally known for motivating us to search for rewards. The difference in the dopamine system in the extrovert’s brain tends to push them towards seeking out novelty, taking risks and enjoying unfamiliar or surprising situations more than others. The amygdala is responsible for processing emotional stimuli, which gives extroverts that rush of excitement when they try something highly stimulating which might overwhelm an introvert.

More research has actually shown that the difference comes from how introverts and extroverts process stimuli. That is, the stimulation coming into our brains is processed differently depending on your personality. For extroverts, the pathway is much shorter. It runs through an area where taste, touch, visual and auditory sensory processing takes place. For introverts, stimuli runs through a long, complicated pathway in areas of the brain associated with remembering, planning and solving problems.
