Regional Specificity of the Cingulate Cortex Thickness Association with the Intensity of Psilocybin Experience: A Replication Study

OpenAlex  – September 25, 2025

Summary

Individual responses to psychedelics are profoundly shaped by brain structure. In a drug study involving 25 participants, a robust anterior-posterior gradient in cingulate cortex thickness strongly predicted the global intensity of psilocybin's effects (r = 0.549). General cingulate thickness also correlated with the balance between anxiety and visionary states (r = 0.495). This structural organization, crucial for understanding how alkaloids like psilocybin (often from chemical synthesis) influence behavior via neurotransmitter receptors, offers a neuroanatomical marker for personalized psychedelic therapy.

Abstract Rationale: Individual variability in psilocybin response is a major challenge for psychedelic-assisted therapy, with structural brain feat...

Therapeutic Alliance and Rapport Modulate Responses to Psilocybin Assisted Therapy for Depression

Frontiers in Pharmacology  – March 31, 2022

Summary

A strong bond with a psychotherapist significantly enhances psilocybin's impact on depression. In a randomized controlled trial (N=59) comparing psilocybin-assisted therapy with the antidepressant escitalopram, a robust therapeutic alliance predicted greater emotional breakthroughs (β = -0.22, R² = 0.42) and mystical experiences in the psilocybin group (n=30). Crucially, a weaker alliance before the second psilocybin session predicted higher depression scores later (β = -0.49). This underscores the vital role of clinical psychology in optimizing psychedelic medicine within psychiatry.

Abstract

Background: Across psychotherapeutic frameworks, the strength of the therapeutic alliance has been found to correlate with treatment outcomes; howe...

Psychedelic N,N-dimethyltryptamine and 5-methoxy-N,N-dimethyltryptamine modulate innate and adaptive inflammatory responses through the sigma-1 receptor of human monocyte-derived dendritic cells.

PloS one  – January 01, 2014

Summary

Psychedelic compounds like DMT may naturally regulate inflammation. Researchers investigated how N,N-dimethyltryptamine (DMT) and 5-methoxy-DMT interact with specific immune cells. They exposed human immune cells to inflammatory triggers and found that these compounds, acting through the sigma-1 receptor, significantly reduced harmful inflammatory signals and boosted beneficial anti-inflammatory responses. This suggests a powerful new role for these molecules in controlling immune balance, offering promising avenues for treating autoimmune and chronic inflammatory conditions.

Psychedelic tourism in Mexico, a thriving trend

PASOS Revista de Turismo y Patrimonio Cultural  – January 01, 2018

Summary

A new form of tourism is thriving in Mexico, where visitors increasingly engage in psychedelic plant consumption. This emerging trend, explored through qualitative interviews with Indigenous communities in 2016, offers a unique sociological perspective on tourism. Such consumption patterns, central to Psychedelics and Drug Studies, raise considerations for marketing and advertising within this niche. Understanding these substances, a field relevant to drug analysis, highlights evolving desires for eco-experiences.

Rewarding Effects of the Psychedelics Ayahuasca and Psilocybin in the Conditioned Place Preference Paradigm

Digital Library of Theses and Dissertations (Universidade de São Paulo)  – May 12, 2025

Summary

Ayahuasca acutely inhibited cocaine-seeking behaviors in mice, preventing both expression and reinstatement of conditioned place preference. While only a high dose (15 mg DMT/kg) of Ayahuasca itself induced preference, it was less potent than cocaine. Psilocybin, another psychedelic, did not induce preference in rats. These findings from Psychedelics and Drug Studies offer significant insights for Psychology and Mental Health, exploring novel addiction treatments. Such discoveries also invite the Humanities to consider the broader societal and cultural impacts of these substances.

A Randomised, Triple-Blind, Dose-Finding Study of the Impact of Psilocybin on Motor Function in Healthy Participants

OpenAlex  – December 23, 2025

Summary

Remarkably, psilocybin appears largely safe for motor activity, suggesting promise for physical medicine and rehabilitation. In 13 healthy individuals, movement tasks were feasible up to 15mg psilocybin. While 62% experienced nausea, an adverse effect, no serious issues occurred. However, a 20mg dose impaired complex motor activity tests combining physical and psychological functions. Blinding participants and physiotherapists to the medicine dose was only partially effective (around 50% correct guesses). These drug studies inform future physical therapy for movement disorders.

Abstract

Abstract Background Psychedelics exert widespread effects on brain activity, but their impact on motor function is unclear. This is clinically rele...

Safety, tolerability, pharmacodynamic and wellbeing effects of SPL026 (dimethyltryptamine fumarate) in healthy participants: a randomized, placebo-controlled phase 1 trial.

Frontiers in psychiatry  – January 01, 2023

Summary

A groundbreaking trial reveals that dimethyltryptamine (DMT), a powerful psychedelic compound, shows promise as a safe treatment option. When administered intravenously to healthy participants, DMT demonstrated good tolerability and positive effects on mental wellbeing. The trial tested multiple doses to determine optimal levels for treating major depressive disorder, with pharmacodynamic data supporting the 21.5mg dose as most effective.

Abstract

Due to their potential impact on mood and wellbeing there has been increasing interest in the potential of serotonergic psychedelics such as N,N-di...

Psilocybin Experiential Therapist Training: Insights from a World-First Study

OpenAlex  – November 17, 2025

Summary

Experiencing psilocybin personally can significantly enhance a therapist's skills for psychedelic-assisted therapy. In a world-first investigation, 14 mental healthcare professionals received a 25 mg psilocybin dose, reporting deeper, embodied understanding of therapeutic principles. They also noted increased empathy and attunement. While no harms occurred, participants identified potential risks: temporary destabilization from challenging material, or projecting their own experience onto clients. Findings suggest an optional experiential component is valuable for trained clinicians with strong reflective capacity, though it's not a complete training solution.

Abstract

Abstract First-hand experience with psychedelics may help clinicians develop skills and knowledge needed to work with the profound changes to consc...
