No results posted yet for this study

Summary

This project will employ functional brain imaging to study the mechanism and immediate and long-term effects of psilocybin, a serotonin receptor 2A agonist, on cortical and cortico-subcortical brain networks in healthy adults.

Conditions

Interventions

DRUG

Psilocybin

Psilocybin is a naturally occurring psychedelic compound produced by psilocybin mushrooms, and has been shown to have antidepressant and anti-anxiety effects after one dose of 25 mg. Common side effects are slight elevations in blood pressure and heart rate. Participants will be randomized to receive either psilocybin or control at two separate imaging timepoints in this study.

DRUG

Methylphenidate

Methylphenidate is a stimulant medication used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy, and is used as an active control for this study because it is metabolized similarly to psilocybin and has similar effects on heart rate and blood pressure. Participants will be randomized to receive either psilocybin or control at two separate imaging timepoints in this study.
