This paper discusses the role that serotonin plays, psychological disorders caused by or coincide with improper serotonin functioning, as well as many medications and drugs available which may affect a person's serotonin levels.

10 years later, in 1964, specific serotonin containing nerve cells, or neurons, were located in the brain (P. Breggin and G.Breggin, 1994). It acts as a neurotransmitter to a discrete group of neurons in the brain (Snyder, 1986). Serotonin is in fact the most widespread neurotransmitter in the brain (P. Breggin and G.Breggin, 1994). It is believed that serotonin is involved in the control of aggression, in sexual behavior, and in the maintenance of mood (Appleton, 2000).
