Editing Serotonin (section)

===Mechanism of action===
At rest, serotonin is stored within the vesicles of presynaptic neurons. When stimulated by nerve impulses, serotonin is released as a neurotransmitter into the synapse, reversibly binding to the postsynaptic receptor to induce a nerve impulse on the postsynaptic neuron. Serotonin can also bind to auto-receptors on the presynaptic neuron to regulate the synthesis and release of serotonin. Normally serotonin is taken back into the presynaptic neuron to stop its action, then reused or broken down by monoamine oxidase.<ref>{{cite journal | vauthors = Fuller RW | title = Pharmacology of central serotonin neurons | journal = Annual Review of Pharmacology and Toxicology | volume = 20 | pages = 111–127 | date = 1980 | pmid = 6992697 | doi = 10.1146/annurev.pa.20.040180.000551 }}</ref>
