The information received by an introvert’s brain from the external world travels through a longer pathway called the acetylcholine pathway. In this pathway, the information crosses many different areas, like the right front insular, which is involved with empathy, emotions and introspection, then the Broca’s region, which is responsible for self-talk, words, and speech. It also crosses the right and left frontal lobes and the hippocampus, each having individual functions.
On the other hand, information in the extrovert brain passes through the shorter pathway called the dopamine pathway, which crosses regions in the brain that process sight, sound, taste, and touch. The acetylcholine pathway, which the information in an introvert’s brain takes, is much longer than the dopamine pathway. Hence, introverts take more time to respond and speak and tend to overthink things.
Now that you know that the makeup of your brain is different, it will probably make more sense to you that you naturally prefer quieter and more peaceful environments and avoid highly stimulating environments.
