Research in Stanford’s Functional Neurosurgery Program focuses on a variety of treatments for movement-related disorders, pain, and epilepsy. Many of the therapies available through the Program utilize the stereotactic neurosurgical techniques developed at Stanford.

Functional Neurosurgery staff collaborate with scientists in the Neuro-Muscular Clinic within the Department of Neurology and Neurological Sciences, Stanford's Pain Program, the Epilepsy Program and Biomotion Research Group.

Deep Brain Stimulation (DBS) for Movement Disorders and Pain Control

Dr. Henderson is among a handful of West Coast neurosurgeons performing DBS implantation and monitoring to treat movement disorders and chronic pain. The implantable pulse generator is a thin insulated wire with four microelectrodes at its tip. It is implanted in brain areas that are known to be involved in the patient's disease, such as the globus pallidus or subthalamic nucleus in Parkinson's patients. The surgeon positions the DBS electrode with submillimeter accuracy using state-of-the-art surgical navigation technology. After recovery the brain area is stimulated through a small device similar to a cardiac pacemaker that is implanted under the skin of the chest. The stimulation parameters can be adjusted across a wide range to maximize the relief of pain or disordered movements. In Parkinson's disease we currently achieve an 85% reduction in symptoms with a 50-60% reduction in medication.
