where is serotonin released from in the brain
Serotonin The neurons of the raphe nuclei are the principal source of 5-HT release in the brain.[32] There are nine raphe nuclei, designated B1-B9, which contain the majority of serotonin-containing neurons (some scientists chose to group the nuclei raphes lineares into one nucleus), all of which are located along the midline of the brainstem, and centered on the reticular formation.[33][34] Axons from the neurons of the raphe nuclei form a neurotransmitter system reaching almost every part of the central nervous system. Axons of neurons in the lower raphe nuclei terminate in the cerebellum and spinal cord, while the axons of the higher nuclei spread out in the entire brain.
Serotonin Serotonin (/ˌsɛrəˈtoʊnɪn, ˌsɪərə-/[6][7][8]) or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Biochemically derived from tryptophan,[9] serotonin is primarily found in the gastrointestinal tract (GI tract), blood platelets, and the central nervous system (CNS) of animals, including humans. It is popularly thought to be a contributor to feelings of well-being and happiness.[10]
Serotonin Serotonin (/ˌsɛrəˈtoʊnɪn, ˌsɪərə-/[6][7][8]) or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Biochemically the indoleamine molecule is derived from the amino acid tryptophan.[9] Serotonin is primarily found in the enteric nervous system located in the gastrointestinal tract (GI tract). However, it is also produced in the central nervous system (CNS), specifically in the Raphe nuclei located in the brainstem. Additionally, serotonin is stored in blood platelets and is released during agitation and vasoconstriction, where it then acts as an agonist to other platelets.[10] Serotonin is popularly thought to be a contributor to feelings of well-being and happiness.[11]
