Serotonin: History, History & etymology & Cellular effects

Serotonin (/ˌsɛrəˈtoʊnɪn, ˌsɪərə-/), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS…
