In recent years, psychedelic-assisted psychotherapies have reentered the realm of rigorous scientific inquiry, garnering much attention from both the psychiatric community and the broader public. Headlines on major media platforms frequently tout the psychedelic future of psychiatry, and patients increasingly ask about the prospect of using psychedelics during their sessions. Despite this...
Abstract Whether occasioned through careful, consistent meditative practice or through quicker means like the ritual ingestion of psilocybin or ayahuasca, global contemplative practices have established effective systems of implementing, directing, and integrating the very kinds of non-ordinary experiences central to psychedelic use. However, contemplative traditions are largely absent from the...
Psychedelics have attracted medical interest, but their effects on human brain function are incompletely understood. In a comprehensive, within-subjects, placebo-controlled design, we acquired multimodal neuroimaging [i.e., EEG-fMRI (electroencephalography-functional MRI)] data to assess the effects of intravenous (IV) N,N-Dimethyltryptamine (DMT) on brain function in 20 healthy volunteers....
The near-death experience (NDE) most generally refers to a state of altered consciousness with various features that can occur during real or presumed near-death circumstances and/or life-threatening incidents. Some NDEs are associated with a nonfatal suicide attempt. This paper discusses how a belief by suicide attempters that their NDEs are a true portrayal of objective spiritual reality can...
The clinical evaluation of hallucinogens and other small molecules, conventionally termed psychedelics, has seen a dramatic increase in the past 5 years. Several key clinical trials recently demonstrated the potential efficacy of these compounds in treating a variety of mental health conditions including depression, anxiety, and substance use disorders. Concurrently, the business and patent...

Introduction Ayahuasca is a traditional brew containing the psychedelic 5-DMT (a tryptamine that acts as a 5HT2A-R agonist) used to achieve non-ordinary states of consciousness, with a long tradition among various cultures in ritual and therapeutic contexts. Ayahuasca is being studied as potential treatment in Mental Health, which has led to non-controlled and recreational use. This has led to...
Abstract The physical basis of consciousness is one of the most intriguing open questions that contemporary science aims to solve. By approaching the brain as an interactive information system, complex network theory has greatly contributed to understand brain process in different states of mind. We study a non-ordinary state of mind by comparing resting-state functional brain networks of...
Introduction Substance use disorders(SUDs) are a major health concern and current treatment interventions have proven only limited success. Despite increasing effectiveness, still about 50–60% relapse within 6–12 months after treatment [Cornelius et al ., Addict Behav. 2003;28 381-386]. SUDs are defined as chronic disorders of brain reward system, motivation, and memory processes that have gone...
For a century, psychedelics have been investigated as models of psychosis for demonstrating phenomenological similarities with psychotic experiences and as therapeutic models for treating depression, anxiety, and substance use disorders. This study sought to explore this paradoxical relationship connecting key parameters of the psychotic experience, psychotherapy, and psychedelic experience. In...
