Overview
The goal of this clinical trial is to learn about the role that inducing neuroplasticity (the brain's ability to adapt and change) plays in the behavioral effects of psilocybin in people who have experienced a mild decline in emotional wellbeing.
Researchers will compare different doses of psilocybin combined with midazolam or placebo to see what dose induces increased wellbeing.
Participants will:
- Receive one of four possible combinations of medications
- Undergo an MRI
- Complete questionnaires
- Undergo transcranial magnetic stimulation (TMS) and EEG
Description
The purpose of this study is to investigate the role that inducing neuroplasticity plays in the behavioral effects of psilocybin in people with modest decrements in emotional wellbeing.
