Serotonin receptors are a type of receptor found in the central nervous system and peripheral tissues that are involved in the regulation of mood, appetite, sleep, and other physiological processes. There are several different types of serotonin receptors, each with its own functions and distribution in the brain and body. The most well-known serotonin receptors are the 5-HT1A and 5-HT2A receptors, which are targeted by many antidepressant and antipsychotic medications. Abnormalities in serotonin receptor function have been implicated in the pathophysiology of psychiatric disorders, and medications that target serotonin receptors are commonly used in their treatment.
