Serotonin (not seratonin), aka 5-hydroxytryptamine or 5HT, acts through a
large variety of receptors on neurons (5HT receptors) and mediates, among
other things, some aspects of higher order brain function. LSD, as well
as mescaline, psilocibin and many other hallucinogenic compounds, act as
agonists (activators) at the 5HT2 subtype of serotonin receptors, as well
as probably others (5HT1C, for ex.). These actions are complex-LSD has
the pharmacological profile of a partial agonist in many respects, for ex.-
but there is not much doubt that activation of 5HT2 receptors is strongly
implicated in so-called "hallucinogenic" activity.

Compounds which inhibit the uptake of serotonin, or promote its release,
are known to be anxiolytic.
