Psilocybin’s acute and persistent brain effects: a precision imaging drug trial

Scientific Data June 5, 2025 Subha Subramanian, Travis Rick Renau, Demetrius Perry et al. 4 citations

Psilocybin (PSIL) is a psychedelic drug and a promising experimental therapeutic for many psychiatric conditions. Precision functional mapping (PFM) combines densely repeated resting state fMRI sampling and individual-specific network mapping to improve signal-to-noise ratio (SNR) and effect size in brain imaging research. We present a randomized cross-over study in which PFM was used to...

Psilocybin desynchronizes the human brain.

Nature August 1, 2024 Joshua S. Siegel, Subha Subramanian, Demetrius Perry et al. 241 citations

A single dose of psilocybin, a psychedelic that acutely causes distortions of space-time perception and ego dissolution, produces rapid and persistent therapeutic effects in human clinical trials1-4. In animal models, psilocybin induces neuroplasticity in cortex and hippocampus5-8. It remains unclear how human brain network changes relate to subjective and lasting effects of psychedelics. Here...
