Role of the 5-HT2A Receptor in Self- and Other-Initiated Social Interaction in Lysergic Acid Diethylamide-Induced States : A Pharmacological fMRI Study, Katrin H. Preller et al., 2018

Role of the 5-HT2A Receptor in Self- and Other-Initiated Social Interaction in Lysergic Acid Diethylamide-Induced States : A Pharmacological fMRI Study Katrin H. Preller, Leonhard Schilbach, Thomas Pokorny, Jan Flemming, Erich Seifritz, and Franz X. Vollenweider The Journal of Neuroscience, 2018, 38, (14), 3603–3611. Doi : 10.1523/JNEUROSCI.1939-17.2018   Distortions of self-experience are critical symptoms of psychiatric disorders and have detrimental effects on social interactions. In light of the immense need for improved and targeted interventions for social impairments, it is important to better understand the neurochemical substrates of social interaction abilities. We therefore investigated the pharmacological and neural correlates of self- and other-initiated social interaction. In [...]

Therapeutic Use of LSD in Psychiatry : A Systematic Review of Randomized-Controlled Clinical Trials Juan José Fuentes, Francina Fonseca, Matilde Elices, Magí Farré and Marta Torrens Frontiers in Psychiatry, 2020, Vol 10, Article 943. doi : 10.3389/fpsyt.2019.00943   Lysergic acid diethylamide (LSD) was studied from the 1950s to the 1970s to evaluate behavioral and personality changes, as well as remission of psychiatric symptoms in various disorders. LSD was used in the treatment of anxiety, depression, psychosomatic diseases and addiction. However, most of the studies were not performed under contemporary standards, and it has taken several decades for a resurgence of interest in LSD research and [...]

The Varieties of the Psychedelic Experience: A Preliminary Study of the Association Between the Reported Subjective Effects and the Binding Affinity Profiles of Substituted Phenethylamines and Tryptamines, Federico Zamberlan et al., 2018

The Varieties of the Psychedelic Experience: A Preliminary Study of the Association Between the Reported Subjective Effects and the Binding Affinity Profiles of Substituted Phenethylamines and Tryptamines Federico Zamberlan, Camila Sanz, Rocío Martínez Vivot, Carla Pallavicini, Fire Erowid, Earth Erowid and Enzo Tagliazucchi Frontiers in Integrative Neuroscience, 2018, 12, 54. doi : 10.3389/fnint.2018.00054   Classic psychedelics are substances of paramount cultural and neuroscientific importance. A distinctive feature of psychedelic drugs is the wide range of potential subjective effects they can elicit, known to be deeply influenced by the internal state of the user (“set”) and the surroundings (“setting”). The observation of crosstolerance and a series [...]

Psychedelics and potential benefits in “healthy normals”: A review of the literature, Sam GANDY, 2019

Psychedelics and potential benefits in “healthy normals”: A review of the literature Sam GANDY Journal of Psychedelic Studies, 2019, 3, (3), 280–287. Doi : 10.1556/2054.2019.029   We are in the midst of a psychedelic research renaissance. With research examining the efficacy of psychedelics as a treatment for a range of mental health indications still in its early stages, there is an increasing body of research to show that careful use of psychedelics can yield a variety of benefits in “healthy normals” and so lead to “the betterment of well people.” Psychedelics have been found to modulate neuroplasticity, and usage in a supportive setting can result [...]

Psilocybin-Assisted Therapy : A Review of a Novel Treatment for Psychiatric Disorders, Kelan Thomas et al., 2017

Psilocybin-Assisted Therapy : A Review of a Novel Treatment for Psychiatric Disorders Kelan Thomas, Pharm.D., M.S., Benjamin Malcolm, Pharm.D., M.P.H., and Dan Lastra, B.S. Journal of Psychoactive Drugs, 2017 Doi : 10.1080/02791072.2017.1320734   Abstract Recent research suggests that functional connectivity changes may be involved in the pathophysiology of psychiatric disorders. Hyperconnectivity in the default mode network has been associated with psycho-pathology, but psychedelic serotonin agonists like psilocybin may profoundly disrupt these dysfunctional neural network circuits and provide a novel treatment for psychiatric disorders. We have reviewed the current literature to investigate the efficacy and safety of psilocybin-assisted therapy for the treatment of psychiatric disorders. There were [...]

The Religious Significance of Entheogenic Drugs, Hugh Asher,

The Religious Significance of Entheogenic Drugs Hugh Asher More Info: This is my unpublished Master's Dissertation.   Abstract This paper examines the use of psychoactive substances such as Psilocybin, Mescaline, and LSD as adjuncts to mystical, religious or spiritual experiences. There is an analysis of the psychological changes and the changes in perception that these substances cause and how these can be interpreted as contributing to religious or spiritual enlightenment. There is also a discussion on the nature of what could be considered a religious experience. An overview of the use of such ‘entheogenic’ drugs from an historical perspective follows, looking specifically at the use of [...]

Psychological Explorations of the Magic Mushroom (Psilocybin) Experience, Part I : Subjective Effects and Time Passage Perception, José Arturo Costa Escobar & Antonio Roazzi, 2011

Psychological Explorations of the Magic Mushroom (Psilocybin) Experience, Part I : Subjective Effects and Time Passage Perception José Arturo Costa Escobar, M.S., Antonio Roazzi, Ph.D. Neurobiologia, 2011, 74, (3-4), 81-97.   ABSTRACT Magic mushrooms are rich in the active compound psilocybin, whose activity on consciousness deeply alters cognitive functions, can promote spiritual/mystical experiences and has high biomedical and psychotherapeutic importance. Twenty-eight participants underwent a magic mushroom experience after consuming dehydrated Psilocybe cubensis mushrooms at the dosage of 55.6 mg/Kg (350 μg/kg of psilocybin). Results of subjective aspects of the experience through the Hallucinogen Rating Scale revealed equivalent dosage effects comparable to other studies and similar [...]

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 [...]
