The Mechanisms of Psychedelic Visionary Experiences - Frontiers frontiersin.org Sep 27, 2017 15 facts
claimEvidence supports the hypothesis that psychedelic experiences involve the emergence of innate cognitive processes from lower brain systems, with visionary experiences resulting from the activation of innate processes based in the mirror neuron system (MNS).
claimPsychedelic experiences do not typically manifest operators that depend on higher-level cognitive integration provided by the prefrontal cortex (PFC) or the self and autobiographical qualities maintained by the Default Mode Network (DMN).
claimHoward Gardner's operators for intrapersonal, interpersonal, bodily-kinesthetic, musical, and naturalist intelligence are prominently manifested in psychedelic experiences, particularly in the form of supernatural entities.
claimPsychedelic and mystical experiences typically involve positive emotions such as happiness and bliss, while negative emotions appear less central, potentially because depression is not an adaptive response.
claimPsychedelic-induced experiences include a sense of ineffable knowledge that is comprehensible through direct unity with that knowledge.
claimThe mental state and intentions of a user, referred to as 'set and setting', are considered the most important determinants of the specific qualities of psychedelic experiences.
claimThe Mirror Neuron System (MNS) is hypothesized to be a mechanism of psychedelic visionary experiences, supported by evidence that psychedelics elicit innate brain functions known as entoptics and that the MNS integrates visual experience and behavior while providing a common basis for self and other perceptions.
referenceThe hypothesis that innate operators explain features of psychedelic experiences is supported by evidence of innate modular functions in entoptic images (Siegel, 1977), the modular structure of the human brain (Gardner, 1983, 2000), cognitive science of religion explanations for supernatural experiences (Boyer, 2001, 2017; Clements, 2017), and the relationship of the MNS (Mirror Neuron System) to the DMN (Default Mode Network) and mimesis (Garrels, 2006, 2011).
claimDirect evidence regarding the specific neuropharmacological causes of psychedelic-induced phenomenal experiences is currently limited, though scientific bases for hypotheses about these underlying causal mechanisms exist.
referenceTagliazucchi et al. published 'Enhanced repertoire of brain dynamical states during the psychedelic experience' in Human Brain Mapping in 2014 (Hum. Brain. Mapp. 35, 5442–5456).
claimThe interpretation of psychedelic visual experiences as symbolic representations is supported by the concept of 'presentational symbolism,' as discussed by Susanne Langer and Harry Hunt.
claimSupernatural experiences are central features of psychedelic visionary experiences in societies worldwide.
claimThe visionary component of psychedelic experience can be measured using the construct of Visionary Restructuralization, as established by Dittrich (1998) and Studerus et al. (2010).
claimRay (2012, 2016) proposes that the diversity in the phenomenology of psychedelic experiences is a consequence of the distinctly different neurotransmitter receptor profiles that each substance engages.
claimResearch supports the hypothesis that mirror neurons and their operation in the mimetic capacity are at the basis of psychedelic and other visionary experiences.
