Intracortical visual prosthesis research - approach and progress

Abstract

Following the early work of Brindley in the late 1960's, the NIH began intramural and extramural funding for stimulation of the primary visual coretex using fine-wire electrodes that are inserted into area VI for the prupose of restoring vision in individuals with blindness. More recently researchers with experience in this projectbecame part of our multi-institutional team with the intention to identify and close technological gaps so that the intracortical approach might be tested in humans on a chronic basis. Our team has formulated an approach for testing a prototype system in a human volunteer. Here, we describe our progress and expectations.
