In terms of non-invasive neuromodulatory treatments, fMRI-based neurofeedback has successfully been used in non-psychiatric samples to train individuals to increase NAcc activity, which also elicited feelings of positive arousal [161]. Future research testing whether fMRI-based neurofeedback training of the NAcc could benefit OCD patients who show altered reward-related functions will be an important direction in the search for novel OCD treatment targets.
