Pilot Study: Effects of Psilocybin on Behavior, Psychology and Brain Function in Long-term Meditators

Pilot basic-science study in long-term meditators (n=10) assessing psilocybin effects on psychological function, behavioural task performance, and brain functioning.

Three study streams: drug sessions (1–2 day-long psilocybin sessions with multiple visits), behavioural/cognitive testing (1–10 visits), and MRI imaging (1–3 scans).

Assessments include task performance, brain imaging measures, and standard safety screening (medical exam, ECG, labs) with restrictions on psychoactive medications and substances.
