UPDATED 2026-06-09 Corrected dataset attribution from Timmermann et al. (2019) to Pallavicini et al. (2021) UPDATED 2026-01-21 Background: Psychedelic substances produce profound alterations in conscious experience, yet the neural mechanisms underlying phenomenal richness remain poorly understood. Static measures of neural integration and complexity have shown limited success in predicting...
Chronic pain is common, costly, and for many, remains inadequately treated by existing pharmacologic and non-pharmacologic approaches. In parallel with growing dissatisfaction with conventional therapies, classic serotonergic psychedelics, such as psilocybin, lysergic acid diethylamide (LSD), ayahuasca, N,N-dimethyltryptamine (DMT), and mescaline, administered alone or within...
Objective: Postpartum depression (PPD) is a debilitating mood disorder with peripartum onset. Current treatment options are limited in PPD. GH001 is a synthetic inhalation formulation of the psychoactive molecule mebufotenin (5-MeO-DMT). This trial investigated the preliminary efficacy and safety of GH001 in adult females with PPD. Methods: This phase 2a, proof-of-concept, open-label trial...

Introduction Psychedelics are hallucinogenic agents that are awakening scientific interest in recent years, especially in the field of mental health. Psychedelics induce non-ordinary states of consciousness and alterations in the emotions and in cognition and could be beneficial in treating some mental illness. Objectives The objective of the poster is to expand knowledge about emerging...
Introduction MM120 (lysergide D-tartrate, a formulation of LSD) is under development as a potential treatment for generalized anxiety and major depressive disorders. How psychedelic drugs interact at the TrkB receptor, a key target of neuroplasticity, is not reported. Objectives The study evaluated binding and functional activity of known serotonergic psychedelic compounds and SRI fluoxetine at...
Introduction Research on psychedelic compounds has grown quickly in the past decade. Yet molecule-specific, quantitative summaries are scattered, making it hard to see how interest differs by compound or over time. Objectives To quantify PubMed-indexed publications on ketamine, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), psilocybin, and psilocin; to describe annual trends...
Ayahuasca is a psychoactive brew containing N,N-dimethyltryptamine (DMT) and β-carboline alkaloids that induces marked alterations in perception, emotion and self-referential processing. However, the multiscale biological organization linking peripheral metabolism, brain network dynamics, neurochemistry, and subjective experience in humans remains poorly understood. Here, we applied an...
Brain waves are ubiquitous phenomena of human brain activity. As they propagate, they coordinate neural communication, shaping conscious perception. Understanding how brain waves unfold across space and time is thus critical for uncovering the neural mechanisms that support and suppress consciousness. Here, we analyzed data from the Human Connectome Project alongside multiple independent human...
Expectations strongly shape participant experiences in clinical trials, contributing to placebo effects that complicate interpretation of outcomes. While quantitative tools exist to measure expectations, their subjective and multidimensional nature, especially for individuals with treatment-resistant depression (TRD), remains underexplored. This study aimed to explore the motivations and...
