This study will examine the effect of a single high dose of psilocybin therapy (30 mg) versus a very low dose (1 mg) as an adjunctive therapy to individuals undergoing standard-of-care buprenorphine treatment for Opioid use disorder (OUD). Effects of adjunctive psilocybin will be determined for longitudinal outcomes of opioid abstinence, compliance with bupr...
The goal of this laboratory study is to establish whether and which microdoses of psilocybin are safe to administer at home to healthy participants. Eligible participants will be given ascending doses of psilocybin trihydrate and a single, interspersed, randomized placebo on separate days in double-blind fashion. The participants will be asked to complete qu...
The aim of this double-blind, placebo-controlled, within-subjects study is to determine whether other psychoactive substances can produce experiences akin to those seen with classic psychedelics. Screening involves a medical and psychiatric examination, including blood draw, history and physical, interviews, and questionnaires. Eligible participants will the...
MLS101 is being developed as a low dose psilocybin, that can be administered to treat neurological and psychiatric conditions. The purpose of this trial is to investigate brain activity, safety, tolerability, and PK of multiple doses of MLS101 in healthy participants. In recent years, high-dose psilocybin has gained attention for it potential therapeutic ben...
Abstract Rapid-acting antidepressants like ketamine and serotonergic psychedelics show promise for treatment-resistant depression (TRD), but the molecular mechanisms that contribute to their therapeutic effects remain unclear. Induced pluripotent stem cells (iPSCs) offer a platform to model human cortical neurons and investigate drug effects in a human-relev...
The goal of this open-label, dose-escalation, prospective study is to evaluate the safety and psychological effects of a Psilocybin and D-Serine formulation in healthy volunteers. The main objectives are: 1. To assess the psychological and physiological effects of psilocybin administered with D-Serine in healthy adults. 2. To determine whether D-Serine modul...
As psychedelic-assisted psychotherapy gains momentum, clinical investigation of next-generation psychedelics may lead to novel compounds tailored for specific populations. 2,5-dimethoxy-4-bromophenethylamine (2C-B) is a psychedelic phenethylamine reported to produce less dysphoria and subjective impairment than the psychedelic tryptamine psilocybin. Despite ...
BACKGROUND: Recent advancements in psychedelic research have highlighted psilocybin's potential therapeutic benefits for various mental disorders. Understanding its effects on brain function and identifying predictors of individual responses are essential for developing effective treatments. METHODS: This double-blind, randomized, crossover, and placebo-cont...
BACKGROUND: Changes in well-being, personality, and personal values have been documented post-psilocybin; however, evidence from placebo-controlled trials is limited. AIMS: To examine the effects of psilocybin versus placebo on psychiatric symptoms, personality, and personal values in healthy participants. Potential mediators were also explored. METHODS: = 2...
Background: Although psychedelics have regained attention as potential treatment tools for various mental disorders, little research has examined their impact on temporal perception. Aims: This double-blinded placebo-controlled study aimed to investigate changes in temporal perception under psilocybin, both through performance during the Temporal Bisection T...
BackgroundThe Altered States of Consciousness Scale (3/5D-ASC or 11-ASC) is widely used to assess non-ordinary states of consciousness, particularly for psychedelic research. However, its original dimensional model (3D-ASC within 5D-ASC) and later 11-subscale structure (11-ASC) have a hierarchically incompatible higher/lower-order structure. Although the 11-...
Background Psychedelics exert widespread effects on brain activity, but their impact on motor function is unclear. This is clinically relevant given the emerging interest in psychedelic-assisted physical therapy for disorders of motor function. This study’s primary objectives examined the feasibility and safety of administering movement tasks following low-t...
Classic psychedelics such as lysergic acid diethylamide (LSD) and psilocybin induce mild cardiovascular activation in addition to their psychological effects. While these effects are well described in healthy adults, little is known about their dynamics in clinical populations undergoing psychedelic-assisted psychotherapy. This retrospective, observational, ...
IntroductionExtant literature suggests that anhedonia, defined as a loss of the ability to feel pleasure or interest, is subserved by dysregulation of reward processing in the central nervous system. Dextromethorphan (DXM), an uncompetitive N-Methyl-d-Aspartate (NMDA) receptor antagonist and sigma-1 (σ1) receptor agonist, is a glutamatergic modulator with an...
This randomised controlled feasibility trial evaluates the Digital Intervention for Psychedelic Preparation (DIPP), a novel 21-day self-guided program designed to prepare individuals for psychedelic experiences. Forty healthy volunteers will be randomly assigned to either a meditation-based intervention or a music-based control condition. Both groups will fo...
The study looks into whether administering psychedelic substances that stimulate the serotonin system influences pro-social behavior when compared to administering substances that stimulate the dopamine system in healthy individuals. Psychedelic substances have been shown to be powerful modulators of social perception and behavior during the acute experience...
Psilocybin induces profound alterations in consciousness, yet prevailing neural models often describe a monolithic change in brain connectivity that may not fully capture the multifaceted nature of the psychedelic state. To test the hypothesis of a composite neural state, this study applied a robust, data-driven framework, Connectome Independent Component An...
Ketamine and psilocybin show potential as therapies for various mental illnesses, including major depressive disorder. However, further investigation into their neural mechanisms is required to understand their effects on the brain. By combining computational modelling with electroencephalography (EEG), we examine the effects of ketamine and psilocybin on hi...
Abstract For many, cognitive and affective health declines through typical aging. Although cognitive and affective symptoms are often studied in isolation, they share substantial overlap, and arise, in part, from common biological processes. Aging is accompanied by diminished neural plasticity, heightened neuroinflammation, and widespread alterations in the ...
