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 psilocybininduced ergotropic arousal. Handwriting area and pressure were also measured in the same subjects.Drug-induced contraction of nearby visual space was inferred from changes of AFP curvature and tilt, as well as from increased handwriting area at drug peak. The ‘rising… Expand
