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.
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 ...
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 ...
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 ...
A study finds that antidepressants don’t boost the feel-good brain chemical serotonin, as previously thought. Here’s what you need to know. Skip to main content. 24/7 Help. For premium support ...
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
Inhibited reversal learning can be associated with the idea that subjects experiencing symptoms of anxiety frustrate easily and are unable to successfully adapt to a changing environment. [49] Thus, anxiety can negatively affect learning when the stimulus and response relationship are reversed or altered.
As luck would have it, “a structure in the brain called the dorsal raphe nucleus is strongly activated in orgasm, and that region is very much associated with production and distribution of ...
