1. THEIR BRAINS PROCESS NEUROTRANSMITTERS DIFFERENTLY
Your internal reward system — ruled by dopamine — is different from an extrovert’s. Both of you produce the same amounts of dopamine, but the brain’s reward center is more active in extroverts. They feel accomplished and happy in community settings and receive gratification from successful social interactions. Introverts, on the other hand, receive less satisfaction from social interactions — they get overwhelmed and want to look for the nearest quiet space.
