The reason why serotonin levels are only high in dominant males, but not dominant females has not yet been established. [ 66 ] In humans, levels of 5-HT 1A receptor inhibition in the brain show negative correlation with aggression, [ 67 ] and a mutation in the gene that codes for the 5-HT 2A receptor may double the risk of suicide for those ...
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. [ 1 ] [ 2 ] [ 3 ] They mediate both excitatory and inhibitory neurotransmission .
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.

Low serotonin levels have been linked to many physical and psychological symptoms, according to Healthline. However, scientists are unsure what actually causes serotonin deficiency.
Long COVID symptoms, like brain fog, may be caused by a reduction in serotonin levels, per new research. Researchers also found that the reason behind long COVID neurological symptoms could start ...
Higher levels of tryptophan in the brain boost serotonin and melatonin production, which can make you feel tired. It’s not necessarily the tryptophan that makes you sleepy but rather the ...
