Ali Rezai is a neurosurgeon interested in advancing the use of brain chip implants in deep brain stimulation and neuromodulation to treat Parkinson's disease, obsessive–compulsive disorder, Alzheimer's disease and traumatic brain injury. In 2014 Rezai was a member of a surgical team who implanted a chip developed by Battelle Research Institute to decode and transmit signals from the motor cortex of a patient's brain to bypass spinal injury and restore limb movement. Although the patient did not achieve functional use of the hand, the approach provided movement to his hand. This surgical procedure was purported to be a technological and breakthrough in neural engineering as the first ever account of "limb reanimation." Rezai is the executive chairman and director of the Rockefeller Neuroscience Institute at West Virginia University. He is the former director of Ohio State University's Neurological Institute and the university's Stanley D. and Joan H. Ross Chair in Neuromodulation and professor of neurosurgery and neuroscience.
