Treatment-resistant obsessive-compulsive disorder (OCD) can be treated with neuromodulatory techniques, both invasive (deep-brain stimulation; DBS), and non-invasive (Transmagnetic Cranial Stimulation; TMS). However, the mechanisms of how either of these interventions exert their therapeutic effects remains unclear. Alfredo uses one-photon calcium imaging with miniaturized fluorescent microscopes to tap into how these neuromodulation approaches can affect cortico-striatal circuitry in a compulsive-like mouse model. Alfredo also uses a behavioral task to better understand how aberrant avoidance behavior may develop in compulsive-like mice.
