Stanford Neurosurgery Research Q&As

The Department of Neurosurgery is a world leader in the fast-paced environment of innovative research translation. Our Department supports over 30 active labs investigating everything from brain injury, deep brain stimulation, brain tumors, epilepsy, pathophysiology and treatment of acute stroke, to the effects of stress and aging on the nervous system. Our Research Q&A series further explores our faculty's current research.
