Psychedelics are mind-altering substances that have shown promising effects in the treatment of neuropsychiatric disorders owing to their antidepressant, anxiolytic and antiaddictive effects. However, data on their developmental toxicity is scarce, which might hinder its therapeutic suitability, and preclinical data on their behavioral effects is mainly rest...
In recent years psychedelics have gained popularity and potential promise in the field of mental health, but for patients diagnosed with bipolar disorder (BD), fears of emerging manic or psychotic symptoms have caused investigators to exclude them from psychedelic research. In this observational study, we explore the motivations, expectations, and personalit...
Prior research has determined that music plays a central role in psychedelic assisted therapy (PAT). While there is a general consensus of the importance of music during PAT, there are only three empirical studies published to date that directly investigate which type of music might best support PAT. Importantly, no review to date has critically analyzed the...
This retrospective observational study examines the effects of psychedelic-assisted psychotherapy (PAP) with lysergic acid diethylamide (LSD) or psilocybin in patients with treatment-resistant depressive, anxiety, or addictive disorders. Data will be analyzed from patients treated at the University Hospitals of Geneva between June 2020 and April 2025 who obt...
Since the earliest LSD research, psychedelics have been claimed to enhance autobiographical memory. Revisiting and processing autobiographical memories has further been suggested to be a major component of the therapeutic action of psychedelics. However, modern psychedelic research has largely neglected autobiographical elements of psychedelic experiences, a...
Abstract Classic serotonergic psychedelics engage 5-HT receptors throughout the nervous system, but how maternal exposure intersects with embryonic brain interfaces is poorly defined. Here we tested in mice whether maternally administered lysergic acid diethylamide (LSD) accesses embryonic cerebrospinal fluid (CSF) and whether embryonic choroid plexus (ChP) ...
Psychedelics, such as psilocybin, lysergic acid diethylamide (LSD), ketamine, and N,N-dimethyltryptamine (DMT), have captured the attention of scientists, artists, and seekers alike for their profound ability to alter consciousness and inspire creativity. The concept of "creation" encompasses multiple interpretations-ranging from generating novel ideas to fo...
Electromagnetic field theories of consciousness propose that consciousness emerges from resonant electromagnetic field interactions rather than purely computational neural processes. This paper examines how psychedelic substances-LSD, psilocybin, ketamine, and 5-MeO-DMT-modulate consciousness through their effects on brain electromagnetic fields, as measured...
Rationale: Recent evidence shows that Lysergic Acid Diethylamide (LSD), even when administered in low, non-hallucinogenic doses, can produce analgesic effects and improve pain tolerance in a sample of healthy volunteers. Such results complement what was already observed with other serotonergic psychedelics such as psilocybin: survey studies and case series i...
Schizophrenia is a highly polygenic disease, and several genetic variants associated with the disease converge on altered synaptic homeostasis. In particular, the gene encoding complement component 4 (C4) showed the strongest association with schizophrenia, and this protein is involved in complement-dependent and microglia-mediated synaptic pruning. As a mat...
The serotonin 2C receptor (5-HT2C) is a G protein-coupled receptor implicated in multiple physiological and psychological processes and has been investigated as a therapeutic target for neuropsychiatric conditions such as obesity, drug abuse, and depression. With renewed interest in serotonergic psychedelics for treating depression, 5-HT2C may contribute to ...
A bstract Contemporary psychedelic research highlights the value of user experience reports, yet their verbose, subjective nature poses challenges for clinical utility. This is the first study to pioneer unsupervised automatic text summarization of psychedelic user experience reports, a domain where no human-annotated reference summaries exist. To address th...
BACKGROUND AND AIMS: Drug discrimination procedures have made important contributions to the pre-clinical investigation of psychedelic drugs, such as psilocybin, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT). One of the most important being to highlight the critical role of central 5-HT2A rece...
Serotonergic psychedelics, including the recreationally used psilocybin and LSD, have become promising therapeutic agents for the treatment of treatment-resistant depression. While it is generally agreed that they exhibit their antidepressant effects by inducing rapid and sustained neuroplasticity, the molecular mechanisms responsible are widely debated. In ...
Psychedelics, derived from the Greek words "psyche" (soul) and "deloun" (revealing), are substances historically and currently considered "soul-revealing". Also termed hallucinogens due to their impact on sensory perception, they are further categorized into hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and mescaline; entactogens or em...
Psychedelics are often queried as a potential therapeutic option in a multitude of conditions, including pain and mental health disorders, with a growing body of patient reports and scientific publications describing potential benefit. This article reviews recent research on psychedelic compounds for treatment of headache disorders. Observational data, case ...
Microdosing psychedelics, the regular use of low doses of LSD or psilocybin, have attracted growing public and scientific interest. This review synthesizes findings from 57 human studies on psychological and physiological outcomes in clinical and non-clinical populations. Reported benefits include improved mood, enhanced cognition, social functioning, and me...
Psychedelics are increasingly used in the general population, yet they are associated with increased risk of psychosis in a minority of users that can experience psychedelic-induced psychosis (
Abstract Classical psychedelics such N,N -dimethyltryptamine (DMT), psilocybin, and lysergic acid diethylamide (LSD) modulate consciousness via serotonergic receptor agonism, and are increasingly investigated for their psychotherapeutic potential. When combined with the monoamine oxidase A (MAO-A) inhibitor harmine-mimicking the pharmacological profile of ay...
