Cerebellar Neuromodulation to Enhance Fear Extinction and Predict Response to Exposure Therapy

Emerging neuroimaging studies have shown that the cerebellum contributes to different aspects of timing, prediction, learning, and extinction of conditioned responses to aversive stimuli, factors that may be relevant to the success of exposure based behavioral therapy. Our goals are to determine the cerebellar contributions to fear extinction by attempting to modulate key pathways in this process by theta burst stimulation. The long term goal is to lay the foundation for future studies in which neuromodulation is used to augment exposure therapy.
