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.
In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue. [9]
Serotonin syndrome, in which an excess of serotonin in the synapses causes a similar crisis of hypertension and mental confusion, could be confused with an adrenergic storm. Serotonin, being a tryptamine (non-catecholamine) involved in higher brain functions, can cause dangerous hypertension and tachycardia from its effects on the sympathetic ...
Serotonin is a neurotransmitter involved in multiple complex biological processes including aggression, pain, sleep, appetite, anxiety, depression, migraine, and vomiting. [10] In humans the effects of excess serotonin were first noted in 1960 in patients receiving an MAOI and tryptophan. [54] The syndrome is caused by increased serotonin in ...
Serotonin, in cooperation with a group I metabotropic glutamate receptor (mGluR) agonist, facilitates LTD induction through augmentation of AMPA receptor internalization. This mechanism possibly underlies serotonin's role in the control of cognitive and emotional processes that synaptic plasticity in PFC neurons mediates.
The combination of dopamine, serotonin and oxytocin is already pretty dreamy, but the brain takes that natural high to the next level when you reach the big O by releasing endogenous (i.e., made ...
[2] [26] There may be a link between lower 5-hydroxytryptamine (5-HT, i.e. serotonin) receptor availability and symptoms of antidepressant discontinuation syndrome. [ 24 ] [ 27 ] Among antidepressants analyzed by Gastaldon et al. (2022), lofepramine , vortioxetine , mianserin , agomelatine , and esketamine are not associated with significantly ...
Robert F. Kennedy Jr.'s confirmation hearing on Wednesday to lead the Department of Health and Human Services saw senators question the environmental lawyer about his views on vaccines, abortion ...
