Serotonin

Serotonin is one of several chemical messengers in the brain, or neurotransmitters, which help brain cells communicate with one another. Among many other functions, serotonin is involved in regulating mood. Problems with making or using the right amount of serotonin have been linked to many mental disorders, including depression, bipolar disorder, anxiety disorder, autism, and schizophrenia.
What is Serotonin?

Serotonin is an example of a neurotransmitter, a chemical messenger that is passed between nerve cells. When a nerve impulse reaches the axon at the end of a nerve, neurotransmitters are released which cross an area called the synapse to be received by a specific receptor on the end of a target nerve. Once received by the target nerve, the neurotransmitter may either excite that nerve to fire its own signal or prevent it from firing the signal.
