The unique neural signature of your trip: Functional connectome fingerprints of subjective psilocybin experience

Using brain‑fingerprinting on fMRI from volunteers given psilocybin or placebo, the study shows psilocybin increases functional‑connectome idiosyncrasy via greater intersubject dissimilarity and shifts idiosyncratic features from frontoparietal regions to the default mode network (DMN). They identify a DMN‑centred connectivity signature—reduced within‑DMN and DMN‑limbic coupling and increased DMN‑attentional connectivity—that predicts subjective psilocybin experience, demonstrating the value of brain‑fingerprinting for pharmacological neuroimaging.

Effects of classic psychedelic drugs on turbulent signatures in brain dynamics

Using a novel turbulence framework that quantifies vorticity (local synchrony) and extends metastability to space and time, the study shows that LSD and psilocybin produce consistent yet discriminable compression of the brain’s functional hierarchy, most notably altering the default mode network. These results quantify how two psychedelics modulate hierarchical brain dynamics and support their proposed mechanistic role relevant to therapeutic applications.
