An excerpt from Wikipedia !
" Serotonin ( 5-HT) is a monoamine neurotransmitter. It's biological function is complex and multifaceted , modulating mood, cognition , reward , learning, memory and numerous physiological processes such as vomiting and vasoconstriction .
Biochemically, the indolemine molecule derives from the amino acid
Tryptophan, via the ( rate – limiting ) hydroxylation of the 5 position on the ring (forming the intermediate
5 – hydroxytryptophan) , and then decarboxylation to produce serotonin .
Serotonin is primarily found in the enteric nervous system located in the grastrointestinal tract ( GI tract ) .
However , It's also produced in the nervous system ( CNS ) , specifically in the Raphe nuclei located in the brainstem , Merkel cells located in the skin and taste receptor cells in the tongue. Additionally, serotonin is stored in blood platelets and is released during agitation and vasoconstriction, where it then acts as an agonist to other platelets . "
As above mentioned , serotonin is responsible for positive thoughts and memory consolidation among other things.
