Differently wired

An intriguing overview of the differences between the brain activity of introverts and extroverts. Summary:

Whereas extroverts are linked with the dopamine/adrenaline, energy-spending, sympathetic nervous system, introverts are connected with the acetylcholine, energy-conserving, parasympathetic nervous system.

Introverts’ and extroverts’ blood travels along different brain pathways, and each pathway is activated by a different neurotransmitter: dopamine in the case of extroverts, and acetylcholine in the case of introverts. Excepts are from this book.
