Criticality supports cross-frequency cortical-thalamic information transfer during conscious states
eLife – December 15, 2023
Summary
A key finding reveals that consciousness relies on a preserved communication channel between the cortex and thalamus, diminishing during unconsciousness. In studies involving 42 human patients, along with mice and rats, information transfer via δ/θ/α waves (1–13 Hz) is encoded by high γ waves (52–104 Hz). Unconscious states, induced by propofol or seizures, disrupt this connection, while the psychedelic 5-MeO-DMT enhances it. This research links thalamic-cortical dynamics to consciousness and introduces a framework to understand disruptions in information transfer.
Abstract
Consciousness is thought to be regulated by bidirectional information transfer between the cortex and thalamus, but the nature of this bidirectiona...

Ever wonder why reactions to a hallucinogen vary so much? New research highlights that individual differences play a key role. Specifically, higher neuroticism is strongly linked to more intense challenging experiences, often called 'bad trips,' with psilocybin. Analyzing data from nearly 3,000 users revealed a clear pattern: greater neuroticism scores predicted stronger difficult encounters. This understanding is crucial for navigating individual responses.
Abstract
Classic hallucinogens (e.g. psilocybin and LSD) have substantial effects on perception, cognition, and emotion that can often be psychologically ch...
Pivotal mental states
Journal of Psychopharmacology – April 01, 2021
Summary
Our brains hold an inherent capacity for profound psychological transformation. A new model proposes 'pivotal mental states' as hyper-plastic brain conditions enabling rapid, deep learning. These states, evolved for adapting to environmental pressures, can be primed by chronic stress and triggered by acute stress. Serotonin 2A receptor activity, robustly induced by certain compounds, reliably activates this natural system, linking specific brain signaling to enhanced learning and significant personal growth.
Abstract
This paper introduces a new construct, the ‘pivotal mental state’, which is defined as a hyper-plastic state aiding rapid and deep learning that ca...
Global Street Food: la cocina de la calle
Diseño interior – January 01, 2009
Summary
Compelling evidence from rigorous trials indicates MDMA's effectiveness in treating PTSD. Psilocybin also shows significant promise for alleviating depression and cancer-related anxiety. While preliminary findings are encouraging for compounds like LSD and ayahuasca, a substance with deep cultural roots, in addressing other psychiatric disorders, the overall database isn't yet sufficient for routine FDA approval. Continued investigation into these compounds is warranted.
Abstract
Randomized clinical trials support the efficacy of MDMA in the treatment of PTSD and psilocybin in the treatment of depression and cancer-related a...
Serotonin 5-HT2A, 5-HT2c and 5-HT1A receptor involvement in the acute effects of psilocybin in mice. In vitro pharmacological profile and modulation of thermoregulation and head-twich response
Biomedicine & Pharmacotherapy – August 29, 2022
Summary
A 5HT2AR antagonist completely suppressed psilocybin-induced head-twitch responses (max 17.07 at 1 mg/kg) in mice, revealing key pharmacology. Psilocybin, a potent hallucinogen, acts via its active metabolite, psilocin, as a serotonin receptor agonist, showing similar binding affinities (79-311 nM) to 5-HT receptors, including the 5-HT1A receptor. Psilocybin's chemistry also impacted body temperature, raising it by 0.67 °C at 0.125 mg/kg, but decreasing it by 1.31 °C at higher doses. A 5HT1AR receptor antagonist reversed this decrease, illuminating neurotransmitter receptor influence.
Abstract
The psychedelic 5-HT2A receptor (5HT2AR) agonist psilocybin (or the active metabolite psilocin) has emerged as potential useful drug for various ne...
Psilocybin biphasically modulates cortical and behavioral activity in mice
OpenAlex – January 20, 2024
Summary
Psilocybin, a serotonergic hallucinogen, dramatically reshapes how the brain processes sound. Neuroscience reveals a 2 mg/kg dose initially boosts activity in the auditory cortex, boosting behavioral responses to stimulus. However, 30 minutes later, mice become less active, and sound responses decrease, while neural "noise" increases. Intriguingly, neuronal selectivity for sounds remains stable. This work illuminates how psilocybin modulates intrinsic versus stimulus-driven activity in the sensory system, potentially explaining hallucinations without disrupting core perception, with implications for areas like the visual cortex and neurotransmitter receptor influence on behavior.
Abstract
SUMMARY Psilocybin is a serotonergic psychedelic believed to have therapeutic potential for neuropsychiatric conditions. Despite well-documented pr...
Psilocybin-assisted physiotherapy for refractory motor functional neurological disorder: protocol for a randomised dose-comparison pilot study
Acta Neuropsychiatrica – November 04, 2025
Summary
A novel approach is being tested to address motor functional neurological disorder (FND), a common and disabling condition currently lacking effective drug treatments. Twenty-four participants with refractory FND will be randomized 1:1 into two groups: one receiving 15 mg psilocybin with movement tasks during the drug's effects, and another receiving 25 mg psilocybin alone. All participants receive eight physiotherapy sessions. This pioneering effort aims to assess the treatment's safety, practicality, and potential to alleviate symptoms, improve motor function, and enhance quality of life. Findings will inform larger investigations into this promising therapeutic direction.
Abstract
Abstract Background: Motor functional neurological disorder (FND) is a common illness associated with significant functional impairment. There are ...
The Rise, Decline, and Fall of LSD
Perspectives in biology and medicine – June 01, 1991
Summary
The urge to transcend self, a core human appetite, led to LSD's profound societal impact after its 1943 discovery. This echoes the Fall of man, where humanity seeks lost spiritual connection. Ancient cultures, as seen in the 3,500-year-old Rig-Veda, integrated natural psychoactive agents into their Religious Studies and Spiritual Practices. LSD temporarily changed America's "brainscape" by the late 1960s, initially explored for medical uses. However, its widespread public use for instant spiritual experiences led to a 1965 ban, underscoring the complex quest for transcendence.

Collective Voices of Healing: Psilocybin Discourse and Meaning-Making on Reddit
Zenodo (CERN European Organization for Nuclear Research) – November 18, 2025
Summary
Analyzing over 19,000 Reddit posts across 40 psychology-related topics reveals trauma as the dominant psychological distress, accounting for the highest engagement from 400,000+ upvotes and comments. This widespread emotional distress, including unmet needs for healing and grief, highlights a significant societal burden. Psilocybin, within frameworks like The Magic Church, offers potential. Such structured practices align with evidence for emotional regulation and meaning-making, suggesting a role for ethically guided approaches addressing public mental health and social psychology.
