Goal: To understand how the nervous system processes information; and translate that knowledge into medical devices for the restoration of lost sensory and motor function, and the treatment of neural pathology.

The overarching goal of the lab is to utilize current neuroscientific understanding and neural engineering principles to translate clinical needs into devices which improve quality of care and patient outcomes. Electrophysiological recordings and electrical micro-stimulation are used to gain an understanding of how the nervous system processes information related to various sensory, motor, and cognitive functions. The results of these experiments are then used to guide implementation of novel devices for the treatment of various neural pathologies. Neural prostheses for treating the profoundly blind or paralyzed are being developed. Additionally, we are undertaking electrophysiological research in human patients using penetrating and non-penetrating electrode arrays aimed at improving our understanding of epilepsy and improving the diagnostic tools available to clinicians.

Decoding spoken words using local field potentials recorded from the cortical surface

Communication in patients with “locked-in syndrome” is often an arduous task. Intuitive and rapid communication may be restored bydirectly interfacing with language areas of the cerebral cortex. We used a grid of closely spaced, nonpenetrating micro-electrodes to record local field potentials (LFPs) from the surface of face motor cortex and Wernicke's area. From these LFPs we successfully classified a small set of words on a trial-by-trial basis at levels well above chance, demonstrating that this approach can be used to potentially restore communication to locked-in patients.
