Cross-Species Evidence for Psilocin-Induced Visual Distortions: Apparent Motion Is Perceived by Both Humans and Rats

This cross-species experimental study (n=21 humans; n=10 rats) finds that psilocin (18.2mg/70kg for humans; 0.3mg/kg for rats) impairs the ability to distinguish between static and moving images in both humans and rats. In humans, the impairment aligns with psilocin plasma levels and self-reported hallucination intensity. In rats, the effect is specific to motion perception, providing the first evidence of psilocin-induced visual distortions across species.

Psilocybin and 4-Bromo-2,5-Dimethoxyphenethylamine (2C-B) at Encoding Distort Episodic Familiarity

This re-analysis of an RCT study (n=20) tested the acute effects of psilocybin and 2C-B on the encoding of emotional episodic memories. The study finds that both psychedelics impair estimates of recollection and familiarity, increase familiarity-based false alarms for emotional stimuli, and affect metamemory, indicating a common neurocognitive mechanism across these drugs.

Neural Mechanisms of Resting-State Networks and the Amygdala underlying the Cognitive and Emotional Effects of Psilocybin

This follow-up fMRI analysis of an RCT of healthy subjects (n=24) finds that psilocybin (15mg/70kg) led to a pattern of decreased top-down effectivity between the default mode network (DMN), salience network (SN), and central executive network (CEN) to the amygdala.

Experiences of Awe Mediate Ketamine's Antidepressant Effects: Findings From a Randomized Controlled Trial in Treatment-Resistant Depression

This randomised controlled trial (n=116) investigated the psychological mechanisms of ketamine's antidepressant effects. Participants receiving ketamine reported significantly heightened feelings of awe compared to those receiving a placebo. Awe experiences, as measured by the Awe Experience Scale (AWE-S), mediated depression outcomes (% improvement in MADRS scores) at multiple time points (24 hours and 5, 12, 21, and 30 days) post-infusion, indicating a potential role of awe in ketamine's therapeutic efficacy for depression.

Comparing neural correlates of consciousness: from psychedelics to hypnosis and meditation

This comparative neuroimaging study (n=107) compares the neural correlates of two pharmacological methods, psilocybin (n=23) and LSD (n=25), and two non-pharmacological methods, hypnosis (n=30) and meditation (n=29), in inducing altered states of consciousness (ASC). The results reveal distinct connectivity patterns associated with pharmacological and non-pharmacological interventions, predictability at an individual level, and unique behavioural-neural relationships between psilocybin and LSD, all contributing to a broader understanding of the mechanisms of ASC and their potential therapeutic applications in psychiatric disorders.

Effective-connectivity of thalamocortical interactions following d-amphetamine, LSD, and MDMA administration

This re-analysis of a double-blind, placebo-controlled, crossover study (n=25) investigated the effects of LSD, MDMA and dextroamphetamine on brain measures (thalamocortical and corticothalamic interactions in resting-state fMRI data). Compared to placebo, all three substances increased the effective-connectivity from the thalamus to specific unimodal cortices while reducing their influence on the thalamus, revealing increased bottom-up and decreased top-down information flow; LSD uniquely increased effective-connectivity to both unimodal and transmodal cortices.
