Study Summary

The investigators want to learn more about how human beings learn not to fear and the impact of changing the fear network in the brain using transcranial Direct Current Stimulation (tDCS) in individuals with obsessive compulsive disorder (OCD). The investigators hope this study will help us understand how future treatments can help patients with OCD better control unwanted fear.

Primary Outcome

Greater reduction in the difference in frontomedial theta event-related spectral perturbation (ERSP) between CS+ vs CS- indicates more complete neural extinction of the conditioned fear response, reflecting diminished differential threat processing such that the previously conditioned stimulus is being processed more similarly to the safe stimulus.

Interventions

  • DEVICE Sham tDCS
  • DEVICE Active tDCS
