Key finding — Psilocybin therapy was associated with increased global integration between brain networks after treatment, and the degree of network change correlated with improvement in depression — a possible neural signature of the antidepressant effect.
Study at a glance
| Field | Detail |
|---|---|
| Institution | Imperial College London |
| Design | Pooled analysis of two clinical-trial imaging datasets |
| Sample size | 59 participants |
| Intervention | fMRI before and after psilocybin therapy, across two trials |

Limitations
Correlational; pooled from trials with different designs; imaging changes do not establish causation of clinical benefit.
Editorial note
A neuroimaging analysis linking psilocybin's antidepressant effect to measurable increases in brain network integration, lending biological plausibility to the clinical findings.
