Abstract Background and Purpose Given the increase in recreational psychedelic use and ongoing efforts to explore psychedelics as therapeutic agents for mental health disorders, there is an urgent need to understand the effect of psychedelics such as psilocybin and N,N-dimethyltryptamine (DMT) on sleep-wake states, which share a bidirectional relationship with mental health. Here, we...
Psilocybin produces an altered state of consciousness in humans and is associated with complex spatiotemporal changes in cortical networks. Given the emphasis on rodent models for mechanistic studies, there is a need for characterization of the effect of psilocybin on cortex-wide network dynamics. Previous electroencephalographic studies of psychedelics in rodents have primarily used sparse...
Psychedelic substances have been used for centuries in various cultural and religious contexts, and more recently, in clinical research and therapy. There is a surge of interest in psychedelics, and psychedelic-assisted psychotherapy is becoming increasingly accessible. However, most individuals using psychedelics do so outside of therapeutic contexts. It is important to understand the adverse...
Serotonergic psychedelics enhance neurophysiological complexity and the repertoire of brain states, whereas general anesthetics produce opposite effects. Serotonergic psychedelics are also known to increase wakefulness and reduce sleep time in rodents. Therefore, we hypothesized that 2,5-dimethoxy-4-iodopamphetamine (DOI), a serotonergic psychedelic, will reverse general anesthesia and restore...
Psilocybin containing mushrooms have been utilized for ceremonial, medicinal, and spiritual purposes for millennia. Recently there has been a surge of scientific interest in the therapeutic potential and mechanistic understanding of serotonergic psychedelics, including psilocybin. Psilocybin is classified as a serotonergic psychedelic because the non-ordinary state of consciousness that it...
Abstract 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 electroencephalogram, have primarily been done...
There is a renewed interest in psychedelic drugs as potential therapeutic agents for the treatment of psychiatric disorders. In particular, psilocybin has shown promise for the treatment of refractory depression1 and major depressive disorder2, and has also been explored as a treatment for tobacco and alcohol abuse3,4. However, despite suggestive evidence5,6, there has been no systematic study...
Abstract There is a renewed interest in the therapeutic potential of psychedelics, including psilocybin, in treating mental health disorders. However, there are no data on the efficacy of psilocybin in alleviating chronic pain. In this study, we investigated the effect of psilocybin on mechanical hypersensitivity and thermal hyperalgesia in a rat model of formalin-induced chronic pain. Adult...
Introduction There is substantial public interest in psychedelics as potential treatments for psychiatric conditions. However, most psychedelics are criminalized under federal law in the USA, so it is unclear whether use occurs with clinical support. Our objective was to assess whether naturalistic psychedelic use occurs with clinical support, interactions between those using psychedelics and...
ABSTRACT Naturalistic psychedelic use among Canadians is common. However, interactions about psychedelic use between patients and clinicians in Canada remain unclear. Via an anonymous survey, we assessed health outcomes and integration of psychedelic use with health care providers (HCP) among Canadian adults reporting past use of a psychedelic. The survey included 2,384 participants, and most...
