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 ...
The MRN is involved in the serotonin pathway. [3] Serotonin (5-HT) is the chief neurotransmitter of the median raphe nucleus. [4] According to one study, it represents the main source of serotonin (5-hydroxytryptamine (5-HT)) in the brain. [3] Stimulation of the MRN significantly increases the amount of 5-HT present in the brain. [5]
Besides mammals, serotonin is found in all bilateral animals including worms and insects, [19] as well as in fungi and in plants. [20] Serotonin's presence in insect venoms and plant spines serves to cause pain, which is a side-effect of serotonin injection. [21] [22] Serotonin is produced by pathogenic amoebae, causing diarrhea in the human ...
Cell group B9 is a group of cells located in the pontine tegmentum, ventral to serotonergic group B8. In the nonhuman primate they are found in the ventral part of the superior central nucleus and adjacent structures. [3] In the rodent they have a more lateral location within the medial lemniscus of the pons and dorsal and medial to it., [4] [5]
The 7 general serotonin receptor classes include a total of 14 known serotonin receptors. [9] The 15th receptor 5-HT 1P has been distinguished on the basis of functional and radioligand binding studies, its existence has never been definitely affirmed or refuted. [10] [11] The specific types have been characterized as follows: [12] [13] [14]

Gut microbes modulate about 60% of your serotonin so that you can use it, and antibiotics disrupt your microbiome severely. Curiously, patients with pre-existing psychiatric symptoms sometimes see ...
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.
