Cortical responses elicited by photovoltaic subretinal prostheses exhibit similarities to visually evoked potentials

Abstract

We have previously developed a wireless photovoltaic retinal prosthesis, in which camera-captured images are projected onto the retina using pulsed near-IR light. Each pixel in the subretinal implant directly converts pulsed light into local electric current to stimulate the nearby inner retinal neurons. Here we report that implants having pixel sizes of… (More)
