serotoninës
Serotonin is a neurotransmitter, a chemical messenger that transmits signals between nerve cells in the brain and throughout the body. It is primarily produced in the central nervous system and the gastrointestinal tract. Serotonin plays a crucial role in a wide range of physiological and psychological functions.
In the brain, serotonin is associated with mood regulation, sleep-wake cycles, appetite, digestion, learning, and memory.
Beyond its role in the brain, serotonin is also a key regulator of gut motility and function.
