Single Dose of Psilocybin Produces Lasting Brain Changes, Study Shows

UCSF and Imperial College London researchers documented in Nature that a single 25mg psilocybin dose produces measurable MRI-visible brain changes lasting up to one month, with increased brain entropy correlating with mental health improvements. Brain activity one hour post-dose predicted the magnitude of later mental health gains.

Why post about this

Psychedelic wellness content is saturated with vibes and short on hard neuroscience. This is the rare study that gives creators MRI-grade evidence to talk about — and the one-month durability finding is the new headline number that will define the conversation for the next 12 months.

Suggested angle

'One dose, one month of measurable change' — explain brain entropy in plain language, what the MRI scans actually show, and why this reframes psilocybin from drug to neuroplasticity catalyst. Be clear-eyed about what the study does and doesn't prove.

Expert consensus

Neuroscientists view brain entropy increases as a credible mechanistic signal; the field consensus is that psilocybin's antidepressant effect is real but durability has been the open question — this study moves that needle.
