Protocol Number: 08-M-0048

Title:

PET Test/Retest Brain Imaging of Cannabinoid CB1 Receptors Using [11C]MePPEP

Number:

08-M-0048

Summary:

The purpose of this protocol is to measure brain CB1 receptors in the hope to better understand how they work, so that one day we can understand how the CB1 receptors are involved in psychiatric, neurological, and behavioral disorders.
