1/18 THREAD. New paper by @marcoaqil and me. We challenge most theories regarding the neural basis of psychedelic action by claiming something quite simple: psychedelics are visionary and most theories don’t take this specific sensory domain into account. sciencedirect.com/science/articl… 2/18 Most neuroscientific models take conceptual inspiration from Huxley's “reducing valve” hypothesis , and the historical qualifications of psychedelics as generic “mind-manifesting”, or “nonspecific amplifiers”, or “meaning-enhancing”, or “suggestibility-inducing” substances.
