Psilocybin and its numerous structural analogues are very interesting neurochemical research tools in the context of psychophysics, specifically with respect to visual sensation and perception and its neural correlates. Moreover, psilocybin has significant potential to provide novel insights into the psychology of perception (i.e., visual qualia). Research is currently still in its infancy-stage but we can expect more systematic studies in the future… The relation between electrochemical input and the phenomenological experience of visual qualia is hitherto an unresolved scientific question (the explanatory gap).
