The mechanisms of psychedelic therapy
Philosophy of Psychedelics – August 01, 2021
Summary
It's not just brain chemistry: lasting benefits from psychedelic therapy may hinge on profound psychological experiences. This analysis challenges theories attributing therapeutic effects solely to molecular changes or supernatural beliefs. Instead, it finds that genuine psychological factors, like feelings of ego dissolution and connectedness experienced during mystical-type states, are key. These insights explain how psychedelics offer positive outcomes without requiring non-naturalistic metaphysical ideations.
Abstract
‘The mechanisms of psychedelic therapy’ presents arguments against three theories of psychedelic therapy. The Molecular Neuroplasticity Theory ascr...
Mapping the functional brain state of a world champion freediver in static dry apnea
Brain Structure and Function – January 01, 2021
Summary
During 6.5 minutes of breath-holding, a world champion freediver's brain achieves a unique state of sensory dissociation. Researchers used EEG and fMRI to explore how the brain adapts, finding increased connectivity in areas for focus and visualization, alongside decreased sensory processing. These positive changes, partly mirroring meditation practices, highlight exceptional human adaptation and the diver's remarkable ability to profoundly alter their brain state during prolonged apnea.
Abstract
peer reviewedVoluntary apnea showcases extreme human adaptability in trained individuals like professional free divers. We evaluated the psychologi...
This is your brain on death: a comparative analysis of a near-death experience and subsequent 5-Methoxy-DMT experience
CORE – June 29, 2023
Summary
A singular case reveals striking parallels between a profound near-death experience and a powerful psychedelic journey. Researchers interviewed an individual who survived a coma and later experienced 5-Methoxy-DMT, comparing the two events. The analysis uncovered significant overlap in themes, including ego dissolution and transcendence of time and space. Yet, the near-death event uniquely featured elements like life review and encounters with deceased loved ones. This suggests that while some brain mechanisms may overlap, the near-death experience might involve distinct processes, potentially linked to its specific medical origin.
Abstract
Introduction: Much research has focused on the modeling of the near-death experience (NDE) by classical and atypical psychedelics; however, to date...
Differential relationship between meditation methods and psychotic-like and mystical experiences.
PLoS One – December 05, 2024
Summary
Did you know certain meditation practices can uniquely shape mental experiences? Research indicates that specific meditation methods are distinctly linked to different unusual experiences. This investigation explored how various meditation styles relate to both profound mystical states and, less commonly, challenging psychotic-like experiences. Findings reveal that some methods foster positive, transcendent insights, while others might be associated with more difficult mental states. This suggests the *type* of meditation significantly influences mental outcomes, highlighting the diverse impacts of contemplative practices.
