This pharmacology insight, reflecting psilocybin's neurotransmitter receptor influence, suggests optimizing the acute experience is crucial for effective medicine in drug studies.
Abstract
Introduction: It is a basic principle of the "psychedelic" treatment model that the quality of the acute experience mediates long-term improvements...
What fMRI studies say about the nature of the psychedelic effect: a scoping review
Frontiers in Neuroscience – July 01, 2025
Summary
Psychedelics like psilocybin profoundly reshape brain function, showing promise for mental health. A comprehensive review of dozens of functional magnetic resonance imaging (fMRI) studies in neuroscience reveals consistent patterns. These serotonergic compounds induce a "de-differentiation" of brain networks, notably impacting the default mode network, thalamus, and amygdala. This insight from cognitive psychology, leveraging diverse fMRI approaches, highlights ego dissolution's importance, advancing our understanding of how these serotonergic substances influence behavior in drug studies through biochemical analysis.
Abstract
Research on psychedelic drugs, such as psilocybin, LSD or DMT, is a burgeoning field, with an increasing number of studies showing their promise in...
Psychedelic Art and Implications for Mental Health: Randomized Pilot Study.
JMIR formative research – December 03, 2024
Summary
Viewing psychedelic art (PA) significantly enhances emotional and mental well-being compared to natural scenery. In a pilot trial with 102 participants aged 18 to 35, those exposed to 300 seconds of PA reported greater relaxation, reduced anxiety, and feelings of euphoria. The qualitative analysis revealed diverse impacts, including sensations of awe and heightened bodily awareness. These findings highlight PA's potential as a digital health tool in art therapy, suggesting it could play a transformative role in promoting mental health and well-being in therapeutic settings.

Reduced Precision Underwrites Ego Dissolution and Therapeutic Outcomes Under Psychedelics
Frontiers in Neuroscience – March 17, 2022
Summary
Psychedelics dramatically shift our perception by reducing the "precision" of how our brains update beliefs, a core concept in Bayesian probability and cognitive psychology. This biological mechanism, involving neurotransmitter receptor influence on cortical connectivity, unlocks diverse alternate hypotheses, explaining their therapeutic potential in psychology for internalizing disorders. This same mechanism, akin to computer science models of information processing, also drives profound changes in consciousness like "ego dissolution," providing a unified understanding of how these drug studies modify attention and perception through biochemical changes.
Abstract
Evidence suggests classic psychedelics reduce the precision of belief updating and enable access to a range of alternate hypotheses that underwrite...
Psilocybin-induced changes in brain network integrity and segregation correlate with plasma psilocin level and psychedelic experience.
European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology – September 01, 2021
Summary
Psilocybin, at a dose of 0.2-0.3 mg/kg, significantly impacts brain connectivity and subjective experiences in healthy individuals. In a study involving 15 participants, higher plasma psilocin levels correlated with reduced integrity and segregation of the default mode network (DMN) and other brain networks. Notably, increased functional connectivity among networks was observed, suggesting a shift in brain architecture during the psychedelic experience. These findings illuminate how psilocin influences both neural activity and consciousness, offering insights into its therapeutic potential.
Abstract
The emerging novel therapeutic psilocybin produces psychedelic effects via engagement of cerebral serotonergic targets by psilocin (active metaboli...
