Improving safety learning and brain connectivity in adults with OCD
Characterization and Modulation of Functional Connectivity and Fear Extinction Abnormalities in Obsessive-Compulsive Disorder
This project sees if gentle brain stimulation plus exposure therapy helps adults with OCD learn safety faster and reduce fear-driven symptoms.

What this research studies
You would come to Yale for brain scans and sessions that measure how networks involved in fear and safety learning work in adults with OCD. Researchers will use a gentle, noninvasive brain stimulation (anodal frontopolar multifocal tDCS) along with exposure and response prevention (ERP) therapy. During visits you will do conditioning and extinction tasks so the team can track how quickly you learn that a situation is safe and how your brain connectivity changes. The researchers will compare those results to understand whether the stimulation speeds safety learning and alters connectivity linked to persistent OCD symptoms.
Who could benefit from this research
Good fit: Adults aged 21 and older diagnosed with obsessive-compulsive disorder who are eligible for exposure and response prevention therapy would be ideal candidates.
Not a fit: People without OCD, children under 21, or individuals with medical contraindications to brain stimulation (for example certain implants or active seizures) may not be eligible or likely to benefit.
Why it matters
Potential benefit: If successful, this approach could make exposure therapy more effective and reduce lingering fear-driven OCD symptoms by improving safety learning and brain network function.
How similar studies have performed: Early pilot work and community volunteer studies suggest frontopolar tDCS can speed safety learning, but larger tests in people with OCD are still novel.
