Read our Post Traumatic Stress Disorder research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand how the brain learns to avoid reminders of trauma — and why this avoidance can make PTSD treatments less effective. This study asks you to view pictures on a computer screen while your brain activity is measured in an MRI machine. By comparing healthy people, trauma survivors, and people with PTSD, the research team hopes to uncover the brain mechanisms behind avoidance so that better treatments can be developed.
Avoidance is one of the biggest obstacles to successful PTSD treatment. Understanding exactly how and why the brain creates avoidance patterns could help doctors design therapies that work better for people struggling with PTSD.

After an initial screening visit, you will attend two study visits on consecutive days within one month. During each visit, you'll look at pictures on a computer screen while researchers measure your skin's electrical response and scan your brain using an MRI machine. The entire process takes place over roughly one month and helps researchers see how your brain responds to different situations.
