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.
