Psilocybin Reveals Hidden Order Beneath Brain Chaos, Study Finds
Monash University researchers conducted a five-year, open-label study with 62 healthy adults to map brain changes after psilocybin using fMRI, EEG, machine learning and questionnaires. They found a reduction in modular brain organization and a reconfiguration of networks—especially the default mode network—producing a “hidden order” linked to participants’ positive experiences and a sense of unity. The strongest global brain changes occurred when listening to ethereal music and were attenuated by visual input like watching a movie, highlighting the role of context in psychedelic effects. While findings may inform psychedelic therapies, the study lacked a placebo group and involved healthy volunteers, not patients.
