Serotonin and Behavior. Serotonin is a common neuromediator in the brain. It belongs to the group of so-called biogenic amines, relatively simple chemicals that facilitate the transfer of signals between the cells of the body.
High serotonin lowers acetylcholine, norepinephrine, and dopamine in the brain and prevents the release of those neurotransmitters. Because of this, too much serotonin relative to the other brain chemicals results in a type of depression, albeit a different kind. Serotonin is a natural tranquilizer and pain reliever.
