Psychological Explorations of the Magic Mushroom (Psilocybin) Experience, Part II : Neuropsychological Measures José Arturo Costa Escobar & Antonio Roazzi, 2011

Psychological Explorations of the Magic Mushroom (Psilocybin) Experience, Part II : Neuropsychological Measures José Arturo Costa Escobar, M.S., Antonio Roazzi, Ph.D. Neurobiologia, 2011, 74, (3-4), 99-112.   ABSTRACT Some investigations conducted with psilocybin and mushrooms of the Psilocybe genus on the human mind point to a peculiarity of these substances to promote a special state of consciousness. The present study measured the effects of dehydrated magic mushrooms on human visual processes and memory utilizing tasks in a pre- and post-test form. We observed defi cits in visual working memory and these results were consistent with other, recent psilocybin studies. However this and other visual mechanisms [...]

Sense of reality, metacognition and culture in schizophrenic and drug-induced hallucinations, Martin Fortier, 2018

Sense of reality, metacognition and culture in schizophrenic and drug-induced hallucinations :  An interdisciplinary approach Martin Fortier In J. Proust & M. Fortier (Eds.) : "Metacognitive Diversity : An Interdisciplinary Approach", 2018. Oxford/New York, Oxford University Press.   Abstract Hallucinations possess two main components : (i) a sensory content; and (ii) a sense that the sensory content is real. Influential models of schizophrenic hallucination claim that both the sensory content and the sense of reality can be explained in terms of metacognitive dysfunction. This chapter assesses whether such a claim holds for schizophrenic and drug-induced hallucinations; it further attempts to determine the actual role of metacognition [...]

Henri Michaux et les gouffres (à propos de l’expérience mescalinienne), François Emmanuel, 2007

Henri Michaux et les gouffres (à propos de l’expérience mescalinienne) François Emmanuel   « Moi n’est jamais que provisoire » (Plume). « J’écris pour me parcourir… » annonçait Henri Michaux. À l’hiver 1954 (il a cinquante-cinq ans) il a amplement parcouru le monde, descendu en pirogue un affluent de l’Amazone, promené son étrangeté en Inde, en Chine, en Malaisie…, ramené de ces pays lointains des notations buissonnières, éparses, décalées, des fables drolatiques. Çà et là il s’est fait entomologiste fantasque ou zoologiste d’animaux fantastiques. Toujours curieux de l’ailleurs mais toujours un peu déçu, il a délaissé ces contrées réelles pour d’autres imaginaires, s’est lancé [...]

Serotonergic hallucinogens/psychedelics could be promising treatments for depressive and anxiety disorders in endstage cancer, Rafael Guimarães dos Santos et al., 2019

Serotonergic hallucinogens/psychedelics could be promising treatments for depressive and anxiety disorders in endstage cancer Rafael Guimarães dos Santos, José Carlos Bouso and Jaime E. C. Hallak BMC Psychiatry, 2019, 19, 321 https://doi.org/10.1186/s12888-019-2288-z   Abstract In a recent issue of the BMC Psychiatry, the evidence of effectiveness of treatments for psychiatric conditions in end-stage cancer patients was reviewed (Johnson, 2018). The review was comprehensive, and included traditional and non-traditional/alternative treatments, including herbal medicines and spirituality. However, evidence showing that classic or serotonergic hallucinogens/psychedelics such as psilocybin and lysergic acid diethylamide (LSD) could be effective treatments for depressive and anxiety disorders in end-stage cancer was not included.

Modulation of Social Cognition via Hallucinogens and “Entactogens”, Katrin H. Preller and Franz X. Vollenweider, 2019

Modulation of Social Cognition via Hallucinogens and “Entactogens” Katrin H. Preller and Franz X. Vollenweider Frontiers in Psychiatry, décembre 2019 doi: 10.3389/fpsyt.2019.00881 Social cognition is a fundamental ability in human everyday lives. Deficits in social functioning also represent a core aspect of many psychiatric disorders. Yet, despite its significance, deficits in social cognition skills are insufficiently targeted by current treatments. Hallucinogens and entactogens have been shown to have the potential to modulate social processing. This article reviews the literature on the influence of hallucinogens and entactogens on social processing in controlled experimental studies in humans and elucidates the underlying neurobiological and neuropharmacological mechanisms. Furthermore, [...]

Psychedelics and music : neuroscience and therapeutic implications, Frederick S. Barrett et al., 2018

Psychedelics and music : neuroscience and therapeutic implications Frederick S. Barrett, Katrin H. Preller & Mendel Kaelen International Review of Psychiatry, 2018 https://doi.org/10.1080/09540261.2018.1484342   ABSTRACT From the beginning of therapeutic research with psychedelics, music listening has been consistently used as a method to guide or support therapeutic experiences during the acute effects of psychedelic drugs. Recent findings point to the potential of music to support meaning-making, emotionality, and mental imagery after the administration of psychedelics, and suggest that music plays an important role in facilitating positive clinical outcomes of psychedelic therapy. This review explores the history of, contemporary research on, and future directions regarding the use [...]
