Sleep paralysis (SP), an REM parasomnia, can be characterized as one of the symptoms of narcolepsy. The SP phenomenon involves regaining meta-consciousness by the dreamer during REM, when the physiological atonia of skeletal muscles is accompanied by visual and auditory hallucinations that are perceived as vivid and distressing nightmares. Sensory impression...
ABSTRACT Studies reporting novel therapeutic effects of psychedelic drugs are rapidly emerging. However, the reproducibility and reliability of these findings could remain uncertain for years. Here, we implemented a multi-institutional collaborative approach to define the robust and replicable effects of the psychedelic drug psilocybin on mouse behavior. Fiv...
Psilocybin, MDMA, and LSD have recently emerged as popular psychedelic substances for use in psychopharmacology in managing various disorders including treatment-resistant depression, PTSD, and anxiety. These substances mainly affect the serotonergic receptors that involve the regulation of consciousness, perceptions, and cognition. These unique alterations ...
Anorexia nervosa (AN) is a severe psychiatric disorder characterized by extreme food restriction, an intense fear of weight gain, and a distorted body image, leading to significant morbidity and mortality. Conventional treatments such as cognitive-behavioral therapy (CBT) and pharmacotherapy often prove inadequate, especially in severe cases, highlighting th...
PurposeTo evaluate the current level of evidence for the use of psychedelics for the management of cancer pain and associated psychological distress.ContentPain is a common symptom of cancer and treatment. However, there are high rates of undertreatment of cancer pain due to the complex underlying biology of the condition, and potentially due to a decrease i...
Psychedelics are emerging as an effective way to combat mental health disorders such as anxiety, depression, PTSD, and substance abuse. Psychedelics such as psilocybin can decrease overactivity in regions of the brain that are associated with anxiety and depression; for instance, psilocybin acts as an agonist on brain receptors to induce consciousness-alteri...
Objective: The aesthetic qualities of psychedelic experiences have long been documented, but their specific contribution to therapeutic outcomes remains unexplored. This study investigates the role of psychedelic-induced aesthetic experiences in predicting positive psychological outcomes. Methods: Using a cross-sectional naturalistic survey, participants who...

Substance use disorder (SUD) is common in psychiatric patients and has a negative impact on health and well-being. However, SUD often goes untreated, and there is a need for psychiatrists, of all specialties, to address this pervasive clinical problem. In this review, the authors' goal is to provide a resource that describes treatments for SUD, using neurosc...
Threatening events and stressful experiences can lead to maladaptive memories and related behaviors. Existing treatments often fail to address these issues linked to anxiety/stress-related disorders effectively. This review identifies dose ranges associated with specific actions across various psychedelics. We examined psilocybin/psilocin, lysergic acid diet...
Background: How the human psyche interacts with the theme of death is fundamental to individual and societal life, profoundly influencing cognition, affect, and behavior. Death-related psychological phenomena, such as death anxiety and acceptance, have been shown in clinical studies to be influenced by psychedelic (LSD and psilocybin) interventions. However,...

Post-Traumatic Stress Disorder (PTSD) is a debilitating mental health condition that can occur after experiencing or witnessing a traumatic event. The impact of PTSD extends beyond the individual, affecting families, communities, and society as a whole. This study aims to investigate the potential of psilocybin as a treatment for PTSD. Psilocybin, after bein...
Abstract Recent clinical trials have found that the serotonergic psychedelic psilocybin effectively alleviates anxiodepressive symptoms in patients with life-threatening illnesses when given in a supportive environment. These outcomes prompted Canada to establish legal pathways for therapeutic access to psilocybin, coupled with psychological support. Despite...
ABSTRACT A variety of classic psychedelics and MDMA have been shown to enhance fear extinction in rodent models. This has translational significance because a standard treatment for posttraumatic stress disorder (PTSD) is prolonged exposure therapy. However, few studies have investigated psilocybin’s potential effect in fear learning paradigms. More specific...
Psychedelics are quite unique among drugs that impact the central nervous system, as a single administration of a psychedelic can both rapidly alter subjective experience in profound ways and produce sustained effects on circuits relevant to mood, fear, reward, and cognitive flexibility. These remarkable properties are a direct result of psychedelics interac...
The serotonin 2 receptor (5HT2R) agonist psilocybin displays rapid and persistent therapeutic efficacy across neuropsychiatric disorders characterized by cognitive inflexibility. However, the impact of psilocybin on patterns of neural activity underlying sustained changes in behavioral flexibility has not been characterized. To test the hypothesis that psilo...
Psilocybe cubensis is a species of psilocybin mushroom (magic mushroom) of moderate potency whose principal active compounds are psilocybin and psilocin. Recent studies have shown the significant procognitive and mood-enhancer effects of Psilocybe cubensis. However, evidence is so limited, especially in preclinical studies. We aimed to investigate the effect...
Background and Aims Psilocybin is a psychedelic drug that may hold promise for a wide range of human health conditions, yet the identification of therapeutic processes and mechanisms of action remains exploratory. We conducted a scoping review on pre-clinical behavioural investigations of psilocybin in non-human animals to help determine the behavioural effe...
