Bierut: The brain is a very complex organ and what's clear is these different types of brain wave patterns are related to numerous complex in our actions between neurotransmitters and some of the brain receptors, and it's some of the balance between how much of these proteins are produced — how are they regulated — are likely to be involved in some of these biologic predispositions.
