Psilocybin’s effect on human brain synaptic plasticity

OpenAlex  – October 10, 2025

Summary

A single dose of psilocybin, a potent psychedelic compound, significantly boosts brain connectivity when administered in a therapeutic-like environment. Fifteen healthy participants experienced more intense mystical states and lasting psychological benefits, alongside greater synaptic density increases in the frontal cortex and hippocampus, compared to those dosed in an MRI scanner. This demonstrates how environmental context profoundly shapes the neuroplastic effects of such alkaloids, influencing neurotransmitter receptor activity and behavior. These findings have crucial implications for future drug studies.

Mindset Over Molecule: Comparing Self-Transcendent and Mystical Experiences Across Recreational Psilocybin, MDMA, and Cannabis Use

OpenAlex  – September 12, 2025

Summary

Mindset, not just the molecule, profoundly shapes psychedelic experiences. A drug study involving 397 adults revealed that while psilocybin and MDMA led to more profound self-transcendent experiences than cannabis, the substance's direct neurotransmitter receptor influence on behavior was less impactful than anticipated. Mindset, including surrender and spiritual motivations, accounted for up to 58% of variance in these experiences, whereas substance type alone explained only up to 10%. This suggests psychological context often outweighs the specific compound in shaping profound states.

Abstract

Abstract Background Self-transcendent and mystical experiences may be key mechanisms underlying psychedelics’ therapeutic effects, yet how these ex...

In naturalistic psychedelic use, group use is common and acceptable

Journal of Psychedelic Studies  – June 19, 2023

Summary

Subjective negative mental health outcomes from psychedelic use are rare and not linked to solo or group modalities, according to naturalistic observation. While solo use was reportedly more common for mental health goals, natural compound pharmacology studies indicate no difference in overall mental health benefit between solo and group settings. A vast majority (95% solo, 91% group) of these experiences occur informally. This challenges clinical psychology’s traditional focus, suggesting group approaches in medicine for mental health could be equally safe and beneficial, effectively minimizing harm.

Acute Psychological Adverse Reactions in First-Time Ritual Ayahuasca Users: A Prospective Case Series.

Journal of clinical psychopharmacology 

Summary

Seven out of 40 first-time ayahuasca participants reported intense psychological challenges during ceremonies, with four meeting criteria for psychiatric disorders beforehand. Remarkably, one month later, two participants no longer exhibited symptoms, while the other two showed significant reductions. These improvements persisted at the six-month mark. However, the majority (six of seven) chose not to participate in further ceremonies, highlighting the importance of appropriate settings and guidance. This suggests that while ayahuasca can provoke acute psychological reactions, it may also lead to positive long-term outcomes.

Right-Wing Psychedelia: Case Studies in Cultural Plasticity and Political Pluripotency

Frontiers in Psychology  – December 10, 2021

Summary

Despite common assertions in *Psychedelics and Drug Studies*, these substances do not inherently lead to liberal politics or environmental concern. *Psychology* reveals psychedelics are "politically pluripotent," non-specific amplifiers of existing "set and setting." Experiences challenging a person's fundamental worldview can shift political beliefs in *any* direction. Conservative, hierarchy-based ideologies, exemplified by figures like Jordan Peterson and members of neo-Nazi organizations, can assimilate psychedelic experiences of interconnection. This challenges simplistic *Cognitive psychology* models of political change, highlighting the complex interplay of individual experience and *Politics*.

Little is known about motives of healthy volunteers to participate in psychedelic trials and how they appraise their study experience retrospective...

A Field-Wide Review and Analysis of Study Materials Used in Psilocybin Trials: Assessment of Two Decades of Research

Psychedelic Medicine  – January 20, 2025

Summary

Psychedelic research documents from numerous psilocybin studies over two decades consistently prioritize participant safety. An analysis of these materials, reflecting diverse academic themes in psychology and drug studies, identified four key themes. Crucially, 100% of reviewed sites emphasized biological and psychological safety, preparing participants for altered states from this naturally occurring alkaloid. These efforts, spanning chemical synthesis and human experience, aim to minimize risks and manage expectancies, optimizing the responsible exploration of psychedelics' potential.

Development of a nomogram for predicting the outcome in patients with prolonged disorders of consciousness based on the multimodal evaluative information.

BMC neurology  – April 23, 2025

Summary

A breakthrough in predicting recovery from severe brain injury reveals that over 50% of patients with disorders of consciousness show improvement within six months. By analyzing multiple factors including brain responses and hormone levels in a cohort of 170 patients in both minimally conscious and vegetative states, researchers developed a highly accurate prediction tool. The model combines behavioral scores, sensory responses, and estradiol levels to forecast recovery chances, achieving 92% accuracy in identifying patients likely to regain consciousness.

Abstract

To establish a nomogram prediction model for the patients with prolonged disorders of consciousness (PDOC) caused by brain injury at six months bas...

The Varieties of the Psychedelic Experience: A Preliminary Study of the Association Between the Reported Subjective Effects and the Binding Affinity Profiles of Substituted Phenethylamines and Tryptamines

Frontiers in Integrative Neuroscience  – November 01, 2018

Summary

The profound diversity of subjective effects from classic psychedelics isn't just about mindset; it's also linked to how these drugs uniquely interact with brain receptors. Research correlating user experiences with drug binding affinity profiles revealed that the variety of reported effects strongly aligns with interactions at serotonin, dopamine, glutamate, muscarinic, opioid receptors, and the Ca+ channel. This advances our neuroscientific understanding of these compounds.

Abstract

Classic psychedelics are substances of paramount cultural and neuroscientific importance. A distinctive feature of psychedelic drugs is the wide ra...
