Helen M. Bronte-Stewart, MD, MSE
Principal Investigator

The John E. Cahill Professor, 
Department of Neurology and Neurological Sciences
Professor, Neurology and Neurological Sciences
Director Stanford Movement Disorders Center
Director Stanford Human Motor Control and Balance Laboratory

Dr. Bronte-Stewart received a Master of Science in Bioengineering and her MD degree from University of Pennsylvania Schools of Engineering and Medicine respectively. Dr. Bronte-Stewart did her internship in medicine and a residency in neurology at the Hospital of the University of Pennsylvania. She completed post-doctoral fellowships in movement disorders in single unit electrophysicology and motor control with Dr. Stephen Lisberger, at the University of California, San Francisco.

Her expertise in single neuronal electrophysiology in primates has been transferred to the operating room where she performs the intra-operative microelectrode mapping of basal ganglia nuclei during deep brain stimulations (DBS) procedures for the treatment of patients with Movement Disorders. Dr. Bronte-Stewart's research focus is on elucidating the mechanisms of abnormal brain activity that contribute to abnormal movement and balance disorders in Parkinson's disease, tremor and dystonia. She has developed new technology to measure human motor control such as a MIDI keyboard, which has been developed by Intel's division of Healthcare Technology. In the Stanford Human Motor Control & Balance laboratory, Dr. Bronte-Stewart and her colleagues are investigating the effects of interventions such as DBS and/or exercise on specific aspects of balance and upper extremity movement in Parkinson's disease. In the operating room, she and her colleagues record electrical signals directly from the human brain and have demonstrated that DBS suppresses an abnormal rhythm in the brain and may act like a brain pacemaker.

Dr. Bronte-Stewart's passion for understanding how the brain controls movement comes from a background in classical and modern dance.
