neurotransmitter regulating mood, sleep, and appetite
Serotonin, also known as 5-HT or 5-Hydroxytryptamine, is a neurotransmitter that plays a crucial role in regulating mood, sleep, appetite, and other physiological functions. It is primarily found in the brain, bowels, and blood platelets, and imbalances in serotonin levels are often linked to conditions such as depression, anxiety, and migraines.
