Summary
AI-generated from the abstractPsilocybin, a hallucinogen, temporarily impairs the brain's ability to compensate for optically induced spatial distortions. At the drug's peak effect, participants showed a marked loss of compensation for these distortions, which then returned to normal as the drug's effects wore off.

Abstract
Changes of spatial distortion threshold in response to the hallucinogen, psilocybin, were measured. A marked loss of compensation for optically induced distortions at drug peak was found. Compensation returned as the drug course elapsed.
