6 Amazing Facts About Serotonin

Significance. In the medical community, serotonin is particularly significant due to its impact on psychiatric health. According to Mayo Clinic’s website, abnormalities in neurotransmitter activity may affect behavior or mood and contribute to the development of depression. Serotonin travels between nerve cells via serotonin receptors. During this process, some serotonin is reabsorbed by certain cells in the brain. The reabsorbed serotonin is then no longer available for transmitting signals between nerve cells. In people with clinical depression, it is thought that too much serotonin is reabsorbed, leaving a low level of serotonin available for neurotransmission.
