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.

Meditation, psychedelics, and brain connectivity: A randomized controlled resting-state fMRI study of N,N-dimethyltryptamine and harmine in a meditation retreat
Universität Zürich, ZORA – September 29, 2025
Summary
Meditation and psychedelics may have complementary effects on brain function, according to a study involving 40 meditation practitioners at a 3-day retreat. Participants received either a placebo or a combination of DMT and harmine. Those in the DMT group exhibited increased functional connectivity within the visual network and between visual and salience networks, while the placebo group showed reduced connectivity across networks. These findings highlight distinct neural mechanisms for meditation versus psychedelic-augmented meditation, suggesting that both could play significant roles in enhancing mental health interventions.
Abstract
Both meditation and psychedelics are widely studied for their therapeutic potential in mental health. Recent research suggests potential synergies ...
