Richard A. Normann Cortical Implants for the Blind Univ. Neuroprosthetics, vision neurophysiology.
Work is ongoing in applied and basic studies of the central nervous system.
Key in this work is the development of three dimensional, silicon based electrode arrays to be used to stimulate or record from the neurons of the central nervous system. Passing currents through arrays implanted in visual or auditory parts of the brain, could produce a sense of sight in the blind or hearing in the deaf. The arrays are also being used to study the parallel processing of sensory information by the retina and higher visual centers.
