Research

Neural Prosthetics, Neural Interfaces, Neural Plasticity


Current Research

Research in the Greger lab focuses on understanding how information is encoded in neural structures and on how to apply this understanding to the treatment of human pathology. 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 neural prostheses for human patients. Neural prosthesis for the profoundly blind and amputees are currently being developed in the lab. Electrophysiological research in humans aimed at understanding and treating epilepsy is also ongoing in the lab. All of this work utilizes the high-channel count micro-electrode array technology developed at the University of Utah and now manufactured by Blackrock Microsystems for interfacing with the nervous system.
