Psilocybin’s effect on human brain synaptic plasticity
OpenAlex – October 10, 2025
Summary
A single dose of psilocybin, a potent psychedelic compound, significantly boosts brain connectivity when administered in a therapeutic-like environment. Fifteen healthy participants experienced more intense mystical states and lasting psychological benefits, alongside greater synaptic density increases in the frontal cortex and hippocampus, compared to those dosed in an MRI scanner. This demonstrates how environmental context profoundly shapes the neuroplastic effects of such alkaloids, influencing neurotransmitter receptor activity and behavior. These findings have crucial implications for future drug studies.

Control group improvement lower in psilocybin trials for depression
The Brown University Psychopharmacology Update – October 10, 2025
Summary
Surprisingly, psilocybin's perceived efficacy in treating depression might be overstated. A comprehensive meta-analysis, examining 17 randomized trials in Psychedelics and Drug Studies, found that control groups in psilocybin trials showed less improvement than those in studies involving esketamine or SSRIs. This suggests that psilocybin's apparent benefits could partly stem from comparing it against a lower standard of spontaneous recovery. Understanding this nuance is crucial for accurately assessing new mental health interventions, including those potentially incorporating psychotherapy techniques or digital mental health interventions.
Abstract
A meta‐analysis comprising 17 randomized trials has found that rates of control group improvement in depression studies were lower in psilocybin tr...
