Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
As if the world required any more misunderstanding around mental health, a new study showing depression isn’t caused by low levels of serotonin is, indeed, contributing to it. “News” to ...
Serotonin: Serotonin is a monoamine neurotransmitter, and has been found to promote avoidance behavior through inhibitory pathways. [19] Specifically, serotonin has been associated with Neuroticism, Agreeableness, and Conscientiousness (traits defined by the Five Factor Model of Personality).

UPenn researchers say they will also look to study Prozac, part of a class of drugs called SSRIs that raise serotonin levels in the brain. "Long COVID seems to come in a variety of forms.
The serotonin "chemical imbalance" theory of depression, proposed in the 1960s, [35] is not supported by the available scientific evidence. [ 35 ] [ 36 ] SSRIs alter the balance of serotonin inside and outside of neurons: their clinical antidepressant effect (which is robust in severe depression [ 37 ] ) is likely due to more complex changes in ...
Serotonin pathways are thought to modulate eating, both the amount as well as the motor processes associated with eating. The serotonergic projections into the hypothalamus are thought to be particularly relevant, and an increase in serotonergic signaling is thought to generally decrease food consumption (evidenced by fenfluramine , however ...
