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.
Your brain produces a chemical called serotonin, housed in the hippocampus in the prefrontal cortex, and is used for nerve cells and brain function. Serotonin is also known as a transmitter and helps pass nerve impulses from one cell to the next.
