Neurological Dysfunction


This set of studies has focused on examining behavioral and  brain mechanisms in patients with neurological disorders, mostly motor dysfunction, particularly Parkinson's disease in current work and cerebellar dysfunction and deafferentation in earlier work.  The aim of these studies is to understand the 
behavioral and brain processes that go awry with neurological disorders while also aiming to reveal how the affected regions and circuits operate in healthy humans.  The outcome of the work also has implications for diagnosis and treatment, particularly from a rehabilitation perspective.
