Brain Scans

About The Study:

This exploratory neurobiological study analyzes the presence of the Cannabinoid Type 1 (CB1) receptor in the brain of those who have been exposed to trauma.

The CB1 receptor may play a role in learning and memory processes. Importantly, CB1 receptors have been found in brain regions that control fear and stress responses

Our study is made up of three appointments: a screening appointment to determine your eligibility, an MRI scan, and a PET scan. You can receive up to $650.00 compensation.

Our goal is to better understand the neurobiological underpinnings of PTSD and those exposed to trauma. This research may be applied to help improve future treatments for PTSD.
