It was found that ergotropic arousal-inducing drugs, such as psilocybin, a Ditran®-type 'glycolate' and D-amphetamine, significantly lower human spatial distortion thresholds, i.e. these drugs interfere with counter-adaptation to optical distortion, or the intention to see the world undistorted. The trophotropic arousal-inducing chlorpromazine®on the other hand promotes such counter-adaptation,...
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.
