Neuromodulation approaches for restoring dexterous control following cortical stroke.

Despite physical therapy, about 50% of stroke survivors must live with impaired hand function, impacting daily activities for the remainder of their life. However, recent studies in rats have suggested that low-frequency cortical stimulation may help alleviate such symptoms. In order to translate this work to humans, Dr. Khanna aims to use a multiscale model of electrophysiological recording to monitor motor and somatosensory activity during dexterous control, comparing affected and unaffected hemispheres in non-human primates (NHP) recovering from a stroke. The results may inform development of therapeutic techniques for stroke-related motor dysfunction, while improving our understanding of neuromodulation.
