Acute psilocybin and ketanserin effects on cerebral blood flow: 5-HT2AR neuromodulation in healthy humans

In a single‑blind cross‑over study of 28 healthy volunteers, acute psilocybin — but not the 5‑HT2A antagonist ketanserin — produced significant global and regional reductions in cerebral blood flow that correlated with plasma psilocin and subjective drug intensity (approximately 11.6% at peak). Psilocybin also caused a 10.5% constriction of the internal carotid artery, providing the first in vivo human evidence of asymmetric 5‑HT2A receptor modulation of cerebral haemodynamics.
