A new study highlighted by ScienceDaily suggests that psilocybin, the psychedelic compound found in magic mushrooms, may keep affecting the brain well after the acute experience ends. Researchers at UC San Diego reported that a single dose led to measurable shifts in brain activity that remained detectable for as long as a month.
The findings point not only to changes in how the brain functions, but also to possible physical changes in brain structure. While the report describes those structural effects cautiously, it adds to growing scientific interest in how psychedelics may influence the brain beyond the short-lived hallucinatory phase.
According to the summary, participants who showed the largest increase in flexible, varied brain activity also tended to report stronger personal effects. That connection may help researchers better understand why psilocybin has drawn attention in studies exploring mental health, perception, and lasting psychological change.
The research adds to a broader wave of psychedelic science focused on what happens in the brain after treatment, not just during the trip itself. If confirmed by further work, the results could help explain why even one dose of psilocybin may produce changes that continue weeks later.
