The primary goal of the Parker Lab is to characterize cerebellar neural circuitry with the goal of improving treatments for complex and devastating cognitive and mood abnormalities that are common in neuropsychiatric diseases. Our research is highly translational as we interrogate cerebellar circuitry in animals using electrophysiology, optogenetics, and pharmacology and compare these data to EEG paired with cerebellar TMS administered in clinical populations. The cerebellum contains more neurons than the rest of the brain combined and although it is most famous for its role in motor control, its contribution to cognitive and affective processes is less clear. Schizophrenia, autism, Parkinson’s disease, depression, and bipolar disorder are all examples of disorders involving cerebellar abnormalities that are characterized in part by impairments in cognition and mood. Using cerebellar modulation, we hope to capitalize on the cerebellum’s diffuse connections with the rest of the brain to identify and restore patterns of neural activity that are aberrant in disease.
