Serotonin, also known as 5-hydroxytryptamine (5-HT), is a neurotransmitter that plays a vital role in various physiological and psychological processes within the human body. Among its many functions, serotonin is involved in the regulation of cognitive function, emotions, memory, and the sleep-wake cycle. Central to these processes are serotonin receptors, which mediate the effects of serotonin signaling in the brain and peripheral tissues.
