Wikipedia: Serotonin
Serotonin (/ˌsɛrəˈtoʊnɪn, ˌsɪərə-/) or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Its biological function is complex and multifaceted, modulating mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
