There has been a resurgence in psychedelic research for managing psychiatric conditions in recent years. This study aimed to present a comprehensive review of the current state of the field by applying a systematic search strategy for articles on the effectiveness and tolerability of four psychedelic-assisted therapies (psilocybin, lysergic acid diethylamide [LSD],...
A growing body of work shows that autonomic signals provide a privileged evidence-stream to capture various aspects of subjective and neural states. This work investigates the potential for autonomic markers to track the effects of psychedelics — potent psychoactive drugs with important scientific and clinical value. For this purpose, we introduce a novel Bayesian framework to estimate the...
The recent years have seen an unprecedented surge of psychedelic research. Studies with psilocybin (colloquially known as magic mushrooms), in particular, have shown promise in ameliorating symptoms of treatment-refractory depression, anxiety, and substance use disorder, among others 1 , 2 . Microdosing, the practice of regularly taking roughly a tenth of full psychedelic doses, is becoming...
Serotonergic psychedelics, such as psilocybin and LSD, have garnered significant attention in recent years for their potential therapeutic effects and unique mechanisms of action. These compounds exert their primary effects through activating serotonin 5-HT2A receptors, found predominantly in cortical regions. By interacting with these receptors, serotonergic psychedelics induce alterations in...
We are currently living through a period of ‘psychedelic renaissance’, with an increased interest, both in clinical research and in society at large, in the use of psychedelic substances such as LSD, psylocybin, DMT and mescaline. This interest, however, has recently led to an increased influx of venture capital and a fast emerging psychedelic start-up ecosystem. In this article, I will discuss...
Serotonergic hallucinogens also referred to as psychedelics, are psychoactive substances that profoundly alter perception, mood, and cognitive processes. These substances, historically intertwined with religious and cultural rituals, offer profound effects that extend beyond mere hallucinations to profoundly altered states of consciousness. Notable compounds like Lysergic acid diethylamide...
Abstract This chapter introduces the book's central question: what is a psychedelic experience? Upon reviewing the exchanges between Aldous Huxley and Humphry Osmond concerning their introduction of the term 'psychedelic', the chapter proposes that we should understand the notion along the lines they intended. Their idea was that substances such as psilocybin and LSD induce experiences that...

Introduction The presence of perceptual disturbances and psychotic symptoms associated with substance abuse are widely known. While the abuse of substances is becoming more widespread, there is a general perception that their use entails fewer risks. 25I-NBOMe is a recently introduced hallucinogenic drug producing visual hallucinations and euphoria. Although people consume it like LSD, its...

Introduction Zebrafish (Danio rerio) has evolved over the years as a preferred organism due to its vast repertoire in research fields that mimic a targeted phenotype, particularly behavioral typologies and specific attributes comparable to murine models and relatively high homology with humans. Considering this consideration, different pharmacological treatments have been tested and proven that...
ABSTRACT Classical psychedelic drugs are thought to increase excitability of pyramidal cells in prefrontal cortex via activation of serotonin 2 A receptors (5-HT2 A Rs). Here, we instead find that multiple classes of psychedelics dose-dependently suppress intrinsic excitability of pyramidal neurons, and that extracellular delivery of psychedelics decreases excitability significantly more than...
