Autism Spectrum Disorder (ASD) is characterized by persistent social-communication deficits, cognitive rigidity, and atypical sensory processing. Current pharmacological treatments, including risperidone and aripiprazole, provide only limited symptomatic relief and do not address the underlying neurobiological mechanisms. Converging evidence implicates dysre...
Aging is associated with chronic, low-grade inflammation (“inflammaging”), which contributes to neuropsychiatric and neurodegenerative disorders such as depression, Alzheimer’s disease, and Parkinson’s disease. Conventional pharmacotherapies often provide limited benefit in older adults and are further complicated by polypharmacy and drug-drug interactions. ...
Psilocybin is studied as innovative medication in anxiety, substance abuse and treatment-resistant depression. Animal studies show that psychedelics promote neuronal plasticity by strengthening synaptic responses and protein synthesis. However, the exact molecular and cellular changes induced by psilocybin in the human brain are not known. Here, we treated h...
Uncovering the neural basis of psychedelics’ potent effects on brain activity and conscious experience has great potential for understanding their therapeutic effects. Numerous studies using functional magnetic resonance imaging (fMRI) uncovered a strong effect of psychedelics on global properties of fMRI signal, but how they map to underlying neural phenome...
Psilocybin, chemically known as (4-phosphoryloxy-N, N-dimethyltryptamine, 4-PODMT), is derived from the psychoactive mushroom genus, Psilocybe. Of the four active metabolites, psilocin readily enters systemic circulation. The psychoactive effects of psilocin are thought to arise through partial agonist effects at the 5-HT2A receptor. Psychedelic drugs, inclu...
Serotonergic psychedelics have attracted considerable interest as promising therapeutic agents. However, the molecular mechanisms linking their acute hallucinogenic-like effects to longer-lasting neuroplastic responses remain incompletely understood, partly because of the scarcity of native neural models suitable for mechanistic studies. Here, we developed a...
Depression and psychological distress are highly prevalent among patients with cancer and are associated with impaired quality of life, reduced treatment adherence, and poorer clinical outcomes. Standard pharmacological and psychosocial interventions often demonstrate limited efficacy or delayed onset of action in oncological and palliative settings. Psilocy...
This open-label pilot study examines whether the hallucinogenic drug, psilocybin, given under supportive conditions, is safe and effective for depression in people with Mild Cognitive Impairment (MCI) or early Alzheimer's Disease (AD). This study will also assess whether psilocybin may improve quality of life in those individuals. This is a pilot study evalu...
The goal of this clinical trial is to learn if psilocybin, given with psychological support, is safe and helps treat anorexia nervosa in young adults. Anorexia nervosa is a serious eating disorder that currently has no approved medicine. Psilocybin is a psychedelic substance that may help the brain form new connections, which could make it easier for people ...
Auditory steady-state responses (ASSRs), particularly at 40 Hz, are promising biomarkers for psychiatric disorders involving dysregulated neural synchronization. Although most ASSR studies have focused on the glutamatergic system, the serotonergic system, specifically 5-HT2A receptor signaling, has received limited attention. Psilocin, the active metabolite ...
Neuroplasticity refers to the ability of the brain to modify synaptic connections and reorganize neural circuits, underpinning cognitive function, emotional regulation, and recovery from injury. Recent advances have redefined adult neuroplasticity as more dynamic and therapeutically accessible than previously thought, spurring investigation into pharmacologi...
In this study, participants will received either psilocybin (the active ingredient found in certain mushrooms) or an inactive placebo (a look-alike tablet with no active drug). The psilocybin is supplied by Filament Health (Burnaby, British Columbia). After psilocybin ingestion, the body quickly converts it into psilocin, which is the form that produces the ...
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 ...
This review examines the therapeutic efficacy of psilocybin for major depressive disorder by integrating findings from clinical trials, meta-analyses, and mechanistic research. A comprehensive literature search across major scientific databases identified empirical studies evaluating psilocybin’s effects on depressive symptomatology, safety, and underlying n...
High Resolution Image Download MS PowerPoint Slide Psilocybin, the phosphorylated prodrug of psilocin, holds therapeutic promise across a range of neuropsychiatric conditions, yet its clinical utility is constrained by acute psychoactive effects. Here, we report the rational design, synthesis, and evaluation of a focused library of fluorinated reversible N -...
The escalating global burden of mental health disorders, coupled with the stagnation of innovation in traditional monoaminergic pharmacotherapy (e.g., SSRIs), has precipitated a critical need for novel therapeutic paradigms. This article presents a comprehensive systematic review of the so-called "Psychedelic Renaissance," focusing on the clinical resurgence...
Psilocybin is a naturally occurring psychedelic compound with potential antidepressant effects. Although it has long been used by humans, primarily for recreational purposes, the molecular mechanisms underlying its actions remain incompletely understood. Here, we examined the acute effects of psilocin, the active metabolite of psilocybin, on excitatory neuro...

BACKGROUND: The claustrum, a subcortical structure densely expressing 5-hydroxytryptamine 2 A (5-HT2A) receptors, has been implicated in sensory integration, emotional regulation, salience, and attention. Despite its hypothesized involvement in the effects of serotonergic psychedelics, the neurochemical impact of these substances on claustral neurotransmissi...
Psilocybe cubensis mushrooms are typically not consumed for their nutritional value. The main reason people ingest these mushrooms is for their psychoactive effects. Recently, there has been growing interest in the potential therapeutic applications of psilocybin-containing mushrooms in a range of psychiatric conditions, including depression, anxiety disorde...
