Career
Nudo joined the faculty of the University of Kansas Medical Center in 1997. He subsequently served in several research and administrative roles, including director of the Landon Center on Aging and director of the Institute for Neurological Discoveries. He held the Marion Merrell Dow Distinguished Professorship in Aging and served as vice chair for research in the Department of Rehabilitation Medicine. In 2017, he was named a University Distinguished Professor at the University of Kansas.
Nudo and his partner, Pedram Mohseni, had co-owned the trademark and the company NeuraLink since 2015. The trademark was acquired by Elon Musk in 2017 and rebranded to Neuralink.
Research
Nudo's research has focused on the neurophysiological mechanisms underlying cortical plasticity, motor learning, and recovery of function after brain injury. Studies using intracortical microstimulation mapping in nonhuman primates demonstrated that representations of skilled movements in adult motor cortex can be modified by motor training, providing evidence for experience-dependent reorganization of adult motor cortex.
Nudo and colleagues subsequently examined cortical reorganization following focal ischemic injury. In a 1996 study published in Science, rehabilitative training of skilled hand movements after a focal motor-cortex infarct prevented loss of the hand representation in adjacent undamaged cortex and, in some animals, resulted in expansion of the hand representation into regions previously associated with movements of the elbow and shoulder. The cortical reorganization was accompanied by recovery of skilled hand function. The study led to the development of experience-dependent models of post-stroke neuroplasticity and rehabilitation, and demonstrated that rehabilitative experience can shape functional reorganization of peri-infarct motor cortex.
Later work extended these principles to neural interfaces and neuroprosthetic approaches to recovery after brain injury. In a 2013 study, Nudo and colleagues used an activity-dependent neural prosthesis that detected neural activity at one cortical site and triggered stimulation at another. In a nonhuman primate model of cortical injury, the intervention improved performance of a skilled reaching task.
