Robert Chen received his MA and medical degrees (MBBChir) from the University of Cambridge in 1989, and MSc degree from the University of Toronto in 1992. He undertook internship at Guy’s Hospital (University of London, London, U.K.), residency in Internal Medicine at Queen’s University (Kingston, Ontario, Canada) and residency in Neurology at the University of Western Ontario (London, Ontario, Canada) followed by three years of fellowship training in human motor control and movement disorders at the National Institute of Neurological Disorders and Stroke at the National Institutes of Health in Bethesda, Maryland. In 1998 he joined the faculty of the University of Toronto. He is board certified in Neurology and Clinical Neurophysiology and sub-specializes in movement disorders. His research interests include human motor physiology and pathophysiology of movement disorders. Dr. Chen’s research is also supported by grants from the Canadian Institutes of Health Research.
Our laboratory is currently investigating the organization of cortical inhibitory and excitatory pathways in the human motor cortex, cortical plasticity, pathophysiology of movement disorders such as Parkinson’s disease and dystonia, the mechanisms of action of deep brain stimulation as a treatment of movement disorders and inhibitory functions of the basal ganglia.The techniques used include single pulse, paired pulse and repetitive magnetic brain stimulation; functional magnetic resonance imaging (MRI); electroencephaolgraphic (EEG) recordings of cortical rhythms and movement-related cortical potentials; magnetoencephalography (MEG); and recordings of local field potentials from deep brain stimulation electrodes in the basal ganglia.
