Recent research investigating MDMA has revealed the neurotoxic effect of the drug on brain serotonin neurons. [1] [3] [6] [7] [8] Long term and potentially permanent changes to serotonergic axons have been noted in animal and primate studies where they were administered doses of MDMA similar to those taken by some human users.
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 ...
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.

The serotonin transporter (SERT or 5-HTT) also known as the sodium-dependent serotonin transporter and solute carrier family 6 member 4 is a protein that in humans is encoded by the SLC6A4 gene. [5] SERT is a type of monoamine transporter protein that transports the neurotransmitter serotonin from the synaptic cleft back to the presynaptic ...
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]
5-Hydroxyindoleacetaldehyde (5-HIAL), also known as 5-hydroxytryptaldehyde or as serotonin aldehyde, is an inactive metabolite and metabolic intermediate of the monoamine neurotransmitter serotonin (5-hydroxytryptamine; 5-HT). [2] [3] [1] 5-HIAL is formed from serotonin by oxidative deamination via monoamine oxidase (MAO).
