WebPsilocin is a high-affinity agonist at serotonin 5-HT 2A receptors, which are especially prominent in the prefrontal cortex. It increases cortical activity secondary to down-stream postsynaptic glutamate effects. It is also active at 5-HT 1A, 5-HT 1D, and 5-HT 2C receptors, although these are thought to play a lesser role in its effects.
