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: a pleasant video—say greenery on #gardentok—can cause release of this hormone that’s known for its mood-stabilizing effects ... to store specific information in memory, the ...
Unlike mood-congruent memory, mood-dependent memory occurs when one's current mood resembles their mood at the time of memory storage, which helps to recall the memory. Thus, the likelihood of remembering an event is higher when encoding and recall moods match up. However, it seems that only authentic moods have the power to produce these mood ...
This region is extremely rich in serotonin transporters and is considered as a governor for a vast network involving areas like hypothalamus and brain stem, which influences changes in appetite and sleep; the amygdala and insula, which affect the mood and anxiety; the hippocampus, which plays an important role in memory formation; and some ...
MDMA is part of the amphetamine family and elicits its positive effects by altering brain serotonin, dopamine and norepinephrine neurotransmitter levels. [2] [6] [13] [14] As the drug begins to take effect, the brain becomes flooded with serotonin which can then become depleted within 3–6 hours following consumption. [14]
Owing to the lack of a widely accepted comprehensive theory of the biology of mood disorders, there is no widely accepted theory of how these changes lead to the mood-elevating and anti-anxiety effects of SSRIs. Their effects on serotonin blood levels, which take weeks to take effect, appear to be largely responsible for their slow-to-appear ...
The main findings are that the current mood we are in affects what is attended, encoded and ultimately retrieved, as reflected in two similar but subtly different effects: the mood congruence effect and mood-state dependent retrieval. Positive encoding contexts have been connected to activity in the right fusiform gyrus.
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.
