Background: The primary psychoactive drug in magic mushrooms, psilocybin induces profound alterations in consciousness through its action at the 5-HT2A receptor. This comprehensive review consolidates current research findings to elucidate the pharmacology, safety profile, and clinical applications of psilocybin.Areas of Uncertainty: Despite initial concerns that psilocybin could cause...

Background: Psychedelic drugs have recently emerged as plausibly effective pharmacological agents for the management of depression, anxiety, and other neuropsychiatric conditions, including conditions that have not benefited from prior interventions. The latter half of the twentieth century marked a revolution in the treatment of depression, anxiety, and psychosis, exemplified by the...

Psychedelics belong to the oldest psychoactive drugs. They arouse recent interest due to their therapeutic applications in the treatment of major depressive disorder, substance use disorder, end-of-life anxiety,= and anxiety symptoms, and obsessive–compulsive disorder. In this review, the current state of preclinical research on the mechanism of action, neurotoxicity, and behavioral impact of...

Psilocybin is a naturally occurring psychoactive compound, which has been used for ages in traditional settings for religious and therapeutic use. Recent studies have renewed interest in psilocybin for its potential therapeutic benefits in treating depression and anxiety. The pharmacodynamics of psilocybin are complex, involving its rapid conversion to psilocin and its activity on various...

The pathophysiology of depression is related to the reduced volume of the hippocampus and amygdala and hypertrophy of the nucleus accumbens. The mechanism of these changes is not well understood; however, clinical studies have shown that the administration of the fast-acting antidepressant ketamine reversed the decrease in hippocampus and amygdala volume in depressed patients, and the magnitude...

Despite the longstanding use of nitrous oxide and descriptions of its psychological effects more than a century ago, there is a paucity of neurobiological investigation of associated psychedelic experiences. We measure the brain's functional geometry (through analysis of cortical gradients) and temporal dynamics (through analysis of co-activation patterns) using human resting-state functional...

Inflammation plays a pivotal role in the development and progression of inflammatory bowel disease (IBD), by contributing to tissue damage and exacerbating the immune response. The investigation of serotonin receptor 2A (5-HT2A) ligands and transient receptor potential (TRP) channel ligands is of significant interest due to their potential to modulate key inflammatory pathways, mitigate the...

Abstract Alcohol Use Disorder (AUD) adversely affects the lives of millions of people, but still lacks effective treatment options. Recent advancements in psychedelic research suggest psilocybin to be potentially efficacious for AUD. However, major knowledge gaps remain regarding (1) psilocybin’s general mode of action and (2) AUD-specific alterations of responsivity to psilocybin treatment in...

α-Ethyltryptamine (AET) is quite an interesting, but perhaps long-forgotten, centrally acting agent. Known for more than 75 years, AET was once clinically available as an antidepressant but was withdrawn shortly after its introduction. AET was subsequently controlled as a U.S. Schedule I substance due to its perceived abuse liability and/or toxicity but remains an agent of interest....
