PurposeDespite most psychedelic substances remaining Schedule I, clinical research exploring psychedelic-assisted therapy (PAT) in oncology is expanding. We sought to assess oncology providers' attitudes toward and understanding of PAT.MethodsWe conducted a cross-sectional survey of healthcare professionals involved in oncology across five academic institutions in California, South Carolina,...
SUMMARY How psychedelics act on cortical dendrites to produce long-lasting structural plasticity remains poorly understood. Here, we characterize the effects of psilocybin on dendritic calcium dynamics in pyramidal tract neurons of the mouse medial frontal cortex. Psilocybin transiently increases calcium event rates in apical dendritic tufts over a time course that parallels the drug’s...
Background. Post-Traumatic Stress Disorder (PTSD) is an important public health challenge typically treated with trauma-focused psychotherapy and Selective Serotonin Reuptake Inhibitors (SSRIs). However, high rates of residual symptoms associated with these standard treatments have led to a renewed interest in psychedelic-assisted therapies. Aim. This review attempts to examine emerging...
AbstractPsychedelic-assisted interventions are complex, context-sensitive interventions in which pharmacological, psychological, relational, environmental, cultural, and temporal processes interact. Trials of psilocybin and related compounds have reported promising but heterogeneous findings across psychiatric, substance-use, and existential indications, while also revealing challenges related...
Serotonergic psychedelics are advancing as psychiatric treatments, yet acute responses vary between individuals and the contribution of sex, a fundamental biological variable, remains largely unexamined. We pooled two double-blind, placebo-controlled studies in healthy volunteers (N = 72; 31 male, 41 female) comparing psilocybin 15 mg, 2C-B 20 mg, and LSD 50 μg. Linear mixed models tested sex...
A resurgent therapeutic frontier, the contemporary renaissance in psychedelic science has accelerated investigation of classic serotonergic psychedelics (psilocybin, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), mescaline), empathogenic entactogenic agents (3,4-methylenedioxymethamphetamine (MDMA)), and glutamatergic dissociatives (ketamine) as adjuncts to psychotherapy. While...
The Psilocybe cubensis mushroom is recognized as the primary source of psilocybin in the Americas, occurring naturally across various regions. This fungus has a long history of use in Mesoamerican rituals due to its capacity to induce altered states of consciousness. The defining characteristic of Psilocybe mushrooms is their psilocybin content. Following ingestion, psilocybin is metabolized...
Pupil diameter is a non-invasive biomarker of brain state, correlating with arousal, attention, cognitive processing, and consciousness. However, existing pupillometry software often lacks scalability and robustness across diverse experimental conditions and species. We introduce Pupil-DLC, an open-source, offline, DeepLabCut-based pipeline for scalable, marker-less pupil tracking, primarily...
There is growing interest in psychedelic compounds such as psilocybin, 3,4-metheylenedioxymethamphetamine (MDMA), lysergic acid diethylamide (LSD), and dimethyltryptamine (DMT) given emerging research on potential uses as treatments for a variety of health conditions. The United States Food and Drug Administration (FDA) has granted multiple “Breakthrough Therapy” designations to various...
Psilocybin-producing mushrooms exhibit considerable biochemical diversity, yet the extent of variability among strains within a single species under standardized conditions remains insufficiently characterized. In this study, we quantified psilocybin, psilocin, baeocystin, norbaeocystin, aeruginascin, and norpsilocin in the fruiting bodies of 14 distinct strains of Psilocybe cubensis. The...
