Serotonin

Chemically named 5-hydroxy-tryptamine, this MONOAMINE transmitter is a widely distributed substance particularly prevalent in the gut, blood, platelets, and pineal gland, as well as in nine major sets of brain neurons (nerve cells). In the 1950s, chemical similarity between serotonin and the chemical HALLUCINOGEN LYSERGIC ACID DIETHYLAMIDE (LSD) focused attention on this NEUROTRANSMITTER in mental illness, a link strengthened by experimental studies in animals and humans. Neurons containing serotonin, a typical monoamine, project widely throughout the brain and spinal cord, and a large number of well-characterized serotonin-receptor subtypes mediate both direct and indirect regulation of ion channels that exist in the membranes of neurons. By regulating these channels, these serotonin RECEPTORS influence the concentration within the neuron of such ions as K+ (potassium) and Ca++ (calcium) and thereby the activity of the cell.
