Blindness is a severe condition affecting both individuals and their families. In the past few decades, there have been many attempts at visual prostheses to restore vision to the blind. So far, these methods have restored rudimentary rather than functional vision. There are many challenges to overcome to reach the goal of true functionality. One issue is that the neuroprosthetic interface has only provided individual phosphenes – flashes of light, rather than perceptual information. This isn’t a simple issue of resolution or contrast. Rather there is a mismatch between the way we present information to the brain, and how the brain interprets it. As such, the field has a broad agreement that we need an improved neural interface. This work explores an optoelectronic system that can combine optogenetic and electrical forms of neural stimulation to achieve the best benefits of both while negating their respective limitations. We present a concept system and its organization for the stimulus of neural tissue.
