Single Psilocybin Dose Linked to Lasting Brain and Mood Changes
A 25-milligram dose increased brain signal complexity and predicted greater insight, with well-being gains lasting up to a month, researchers said.
- On Tuesday, Nature Communications published a study showing a single 25-milligram dose of psilocybin causes lasting physical brain changes in 28 healthy adults, with increased neural density persisting one month after the experience.
- Neuropsychopharmacologists at the University of California, San Francisco recruited 28 adults who had never used psychedelics to investigate how the compound found in 'magic mushrooms' initiates brain plasticity. Scientists previously lacked data on structural changes during first-time use.
- During the active session, EEG readings showed increased brain entropy within 60 minutes, signaling complex neural activity. One month later, diffusion tensor imaging revealed white matter tracts linking the prefrontal cortex became denser, indicating structural integrity.
- Participants reported the experience was the 'single most' unusual state of consciousness they had ever experienced, with about 70% noting increased well-being two and four weeks later. Senior author Robin Carhart-Harris linked these improvements to psychological insight.
- While authors caution larger groups are needed to replicate these findings, last month President Donald Trump signed an executive order to expedite psychedelic research on psilocybin and ibogaine, potentially supporting future therapeutic studies.

Single psilocybin dose linked to lasting brain and mood changes
Researchers at UC San Francisco and Imperial College London have shown that a single dose of psilocybin, the psychedelic compound found in magic mushrooms, causes likely anatomical brain changes that last for up to a month after the experience.
One psilocybin dose may reshape brain wiring a month later
A new paper in Nature Communications, covered by Ian Sample at the Guardian, claims a single 25mg dose may leave behind anatomical changes in the wiring itself, still visible 30 days on. Researchers at UC San Francisco and Imperial College London recruited 28 psychedelic-naive adults and gave each of them a token 1mg primer, then a full 25mg session a month later. — Read the rest The post One psilocybin dose may reshape brain wiring a month late…
Psychedelic science breakthrough: Increased brain entropy from psilocybin predicts lasting psychological insight and well-being
A recent study published in the journal Nature Communications suggests that a single high dose of psilocybin can cause lasting changes in human brain connectivity and psychological well-being. Scientists found that these brain changes provide evidence of increased mental flexibility and insight lasting at least a month after the experience. The research offers a rare glimpse into the biological and psychological shifts that occur when a person t…
