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.
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 ...
Monoaminergic systems, i.e., the networks of neurons that use monoamine neurotransmitters, are involved in the regulation of processes such as emotion, arousal, and certain types of memory. It has also been found that monoamine neurotransmitters play an important role in the secretion and production of neurotrophin-3 by astrocytes, a chemical ...
Serotonin-reuptake transporters are dependent on both the concentration of potassium ion in the cytoplasm and the concentrations of sodium and chloride ions in the extracellular fluid. In order to function properly the serotonin transporter requires the membrane potential created by the sodium-potassium adenosine triphosphatase.
The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems.
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 ...
In the brain, said Becker, B6 “aids in the synthesis of neurotransmitters — e.g., serotonin, dopamine, gamma-aminobutyric acid — and helps reduce homocysteine levels in the blood.”
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 ...
