Introvert or an extrovert? Let the brain decide

Genetics has a small hand in deciding our nature of introversion or extroversion. But, the behavior of the dopamine system in our brain, which affects learning abilities, is largely responsible for this inclination. A similar simulation will be processed in a very different manner in an introvert than an extrovert. An extrovert tends to react to an emotional stimulation more quickly and intensely which might be overwhelming for an introvert.
