Photostimulator for optogenetic retinal prosthesis

摘要

The discovery that neurons can be photostimulated via genetic incorporation of artificial opsins offers potential for many new forms of neural prosthesis. In this work, we demonstrate a photostimulator which has both the irradiance requirement and the spatial resolution for retinal prosthesis. We characterise its electrical and optical properties and show its ability to accurately stimulate individual action potentials.
