Psilocybin-Induced Transformations of Visual Space

Summary
Psilocybin, a potent hallucinogen, profoundly alters how we perceive visual space. Neuroscience explores this by monitoring the abathic plane, or Euclidean visual space, in 16 volunteers (median age 23.5 years) given 160 µg/kg psilocybin. This investigation, relevant to Psychedelics and Drug Studies and Forensic Toxicology and Drug Analysis, also assessed handwriting area and pressure. Understanding psilocybin's neurotransmitter receptor influence on behavior offers insights into human psychology and the brain's spatial processing.
Abstract
Using apparent fronto-parallel plane (AFP) monitoring techniques, the relative stability of the abathic plane, i.e., Euclidean visual space, was investigated in 16 volunteers with a median age of 23.5 years under 160 µg/kg psilocybin-induced ergotropic arousal. Handwriting area and pressure were also measured in the same subjects.
