Introvert brains

Introverts use their brains more:

Introverted children enjoy the internal world of thoughts, feelings and fantasies, and there's a physiological reason for this. Researchers using brain scans have found introverts have more brain activity in general, and specifically in the frontal lobes. When these areas are activated, introverts are energized by retrieving long-term memories, problem solving, introspection, complex thinking and planning.

Marti Olsen Laney will soon have a book on introverted kids.
