Study Overview

The purpose of this study is to find out if PET can detect the release of dopamine from nerve endings into synapses, and how the amount of dopamine released varies with the consumption of alcohol or caffeine.

This study takes about 10 hours over 2-3 days.  Up to $200 for participation.  We are interested in people who regularly use alcohol and people who drink alcohol occasionally.  If you qualify, you'll get an MRI scan and PET scans of your brain.
