Cutting Edge. Neurosurgeon Zachary Levine, 37, is a pioneer in the use of deep-brain stimulation, a treatment for neurological disorders in which misfiring nerve cells are tamed by electrodes implanted in the brain and connected to a generator in the chest. After surgery, patients have walked away from wheelchairs; some with Parkinson's stop shaking. Based at the Washington Brain & Spine Institute, Levine also holds a patent for cellular transplantation for neurodegenerative diseases. But he's not all business: "My parents taught me how to be a good doctor and a good person. Enjoying nature with my wife and little girls keeps me balanced."
