Background Recent studies have intensively explored the potential antidepressant effects of psilocybin. However, important variables such as previous experience, repeated administration, setting and sex remain underexplored. This study describes the acute psilocybin experience and long-term effects in a small sample of healthy individuals. Methods In a doubl...
With its catchy title, historian Benjamin Breen's Tripping on Utopia brings together controversial findings about the human mind, social engineering, and professional responsibility. He delineates the time frame and focus of an inquiry into psychoactive drug research by stating that “Timothy Leary and the Baby Boomers did not usher in the first psychedelic e...
Disorders of consciousness (DoC), including the unresponsive wakefulness syndrome (UWS) and the minimally conscious state (MCS), have limited treatment options. Recent research suggests that psychedelic drugs, known for their complexity-enhancing properties, could be promising treatments for DoC. This study uses whole-brain computational models to explore th...
BACKGROUND: Psychedelic substances reliably induce marked altered states of consciousness (ASC), which may be important for lasting effects and clinical outcomes of psychedelic intervention. Several instruments are available to measure the acute psychedelic experience, of which the Five Dimensional Altered States of Consciousness Questionnaire (5D-ASC) is co...
Recent experience with off-label use of ketamine and recent challenges experienced in research with MDMA and psilocybin provide additional perspectives on how best to continue development of experimental psychedelic medications. Andrews et al. [1] provide a valuable perspective by noting the parallels between the ongoing deregulation of cannabis and what is ...
Background: Research investigating high-dose, high-support psilocybin-assisted therapy reports significant psychological benefits, increased consciousness, and an enhanced socio-cognitive niche, resulting in empathy, connection, creativity, and overall well-being. These qualities lend themselves well to the bonding, emotional regulation, and attachment requi...
When the Saskatchewan-based British psychiatrist Humphry Osmond first wrote to his fellow British émigré, novelist Aldous Huxley, he could have had little idea of how the ripples of their private correspondence of the early 1950s would reverberate across the world and into the future. But here we are in 2024, and the term that Osmond coined-‘psychedelic’-is ...
Abstract Background Previous international clinical trials have indicated that mystical experiences resulting from the consumption of classic psychedelic drugs, such as psilocybin, may represent a subjective psychological mechanism of action associated with therapeutic effects for various mental disorders. The revised 30-item Mystical Experience Questionnair...
Psychedelics, substances known to alter perception, mood, and consciousness, have been used across various cultures for centuries, often in religious ceremonies to facilitate spiritual experiences. Lysergic acid diethylamide (LSD) was used clinically from the 1950s until its ban in 1967. Recently, there has been a resurgence of interest in psychedelics for t...
Ketamine is classified as a dissociative anaesthetic that, in sub-anaesthetic doses, can produce an altered state of consciousness characterised by dissociative symptoms, visual and auditory hallucinations, and perceptual distortions. Given the anaesthetic-like and psychedelic-like nature of this compound, it is expected to have different effects on brain dy...
Exploring the intricate relationship between brain's structure and function, and how this affects subjective experience is a fundamental pursuit in neuroscience. Psychedelic substances offer a unique insight into the influences of specific neurotransmitter systems on perception, cognition and consciousness. Specifically, their impact on brain function propag...
Intense interest surrounds current research on psychedelics, particularly regarding their potential in treating mental health disorders. Various studies suggest a link between the subjective effects produced by psychedelics and their therapeutic efficacy. Neuroimaging evidence indicates an association of changes in brain functional connectivity with the subj...
We are in the midst of a polycrisis, with any number of thoughts on how to approach the intersecting global crises of environmental, social, political, and other issues. One line of thinking for re...
This study explores the relationship between psychedelic use and insight among Indian adults aged 18 to 40 years. Psychedelics, such as LSD and psilocybin, are known for altering consciousness and potentially enhancing self-awareness. A total of 100 participants (79 males and 21 females) completed the Psychedelic Integration Scale (PIS), which includes the I...
N,N-dimethyltryptamine (DMT) is a psychoactive substance with similar effects such as LSD or psilocybin. However, DMT is less well characterized than the latter substances. The present study is a modern randomized cross-over trial, investigating different continuous intravenous DMT dose rates over a broad dose range. Thus, different doses will be tested and ...
The use of psychoactive substances for ritual, spiritual and medicinal purposes stretches back into prehistory and has been a common feature of many diverse cultures and societies globally. Psychedelics, with their unique ability to amplify feelings of connectedness and openness, may have also served as tools for promoting tribal cohesion and trust in ancien...
BACKGROUND: The primary psychoactive drug in magic mushrooms, psilocybin, induces profound alterations in consciousness through the 5-HT2A receptor. This review consolidates current research findings to elucidate the pharmacology, safety profile, and clinical applications of psilocybin. AREAS OF UNCERTAINTY: Despite initial concerns that psilocybin could cau...
Abstract Psychedelic therapy has the potential to become a revolutionary and transdiagnostic mental health treatment, yielding enduring benefits that are often attributed to the experiences that coincide with peak psychedelic effects. However, there may be an underrecognized temporal structure to this process that helps explain why psychedelic and related al...
Psychedelic substances induce profound alterations in consciousness. Careful preparation is therefore essential to limit adverse reactions, enhance therapeutic benefits, and maintain user safety. This paper describes the development of a self-directed, digital intervention for psychedelic preparation. Drawing on elements from the UK Medical Research Council ...
Psilocybin produces an altered state of consciousness in humans and is associated with complex spatiotemporal changes in brain networks. Given the emphasis on rodent models for mechanistic studies, there is a need for characterization of the effect of psilocybin on brain-wide network dynamics. Previous rodent studies of psychedelics, using electroencephalogr...
