Serotonergic psychedelics hold promise as a treatment modality for various psychiatric disorders and are currently applied in psychedelic-assisted psychotherapy. We investigated the learning effects of the serotonin receptor agonist psilocybin in a probabilistic cue-reward task with emotional cues in the form of neutral or fearful faces, presented either con...

Diverse symptomatology makes Fragile X Syndrome (FXS) difficult to treat, and currently there are no approved prevention or treatment methods for FXS. Current therapies, including pharmaceutical and behavioural interventions, offer a patchwork of solutions that have limited efficacy and high toxicity. The current study aims to examine psilocybin as a safe tr...
Entheogens, a class of psychoactive substances with profound cultural and religious significance, have been utilized for centuries across diverse traditions for healing, spiritual exploration, and communication with the divine. Their historical usage spans continents, from the pre-Columbian Americas to traditional African practices and Ayurvedic medicine in ...
Introduction: Patients with incurable illnesses often experience existential distress, profoundly impacting their well-being. Current medical approaches have limitations in addressing these burdens. Psilocybin, a promising psychedelic compound, may offer therapeutic benefits. This pilot survey study aimed to investigate the attitudes and openness toward psil...
Psilocybin, and its metabolite psilocin, induces psychedelic effects through activation of the 5-HT2A receptor. Psilocybin has been proposed as a treatment for depression and anxiety but sometimes induces anxiety in humans. An understanding of mechanisms underlying the anxiety response will help to better develop therapeutic prospects of psychedelics. In the...
Introduction Recently, the pros and cons have been debating in Korea even before the approval of use of medical marijuana with very strict limitations. And the next controversial topic is psychedelics. In 1890, when mescaline was first isolated from peyote cactus, clinical researches began, but due to its harmful effects, it was thereafter legally prohibited...
Psychedelics are mainly from the class of psychoactive substances whose action is to produce changes in the perception, mood, cognitive behavior, and processes of a person. This psychedelic drug creates an alteration in a person’s thinking, sense of time, and emotions. Hallucinations can be a main cause for people who take psychedelics. Mainly, these psyched...

When Oregon's first psilocybin service center opened in June 2023, allowing those over 21 to take mind-altering mushrooms in a state-licensed facility, the psychedelic revival that had been unfolding over the past two decades entered an important new phase.Psilocybin is still illegal on the federal level. But now, as researchers explore the therapeutic poten...
Psychedelic substances induce profound alterations in consciousness. Careful preparation is therefore essential to limit adverse reactions, enhance therapeutic benefits, and maintain user safety. This paper describes the development of a self-directed, digital intervention for psychedelic preparation. Drawing on elements from the UK Medical Research Council ...
The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sampl...
Background: Internationally, there is a growing interest in the potential benefits of psilocybin-assisted therapy to treat existential distress at the end of life. However, the social acceptability of this therapy is not yet well known. Aim: This study assesses the social acceptability of the medical use of psilocybin to treat existential distress at the end...
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...
Psychedelic agents, such as LSD and psilocybin, induce marked alterations in consciousness via activation of the 5-HT2A receptor (5-HT2ARs). We hypothesize that psychedelics enforce a state of synthetic surprise through the biased activation of the 5-HTRs system. This idea is informed by recent insights into the role of 5-HT in signaling surprise. The effect...
