Visual Neuroprostheses for Impaired Human Nervous System: State-of-the-Art and Future Outlook

Abstract

Aim of the Study: This review discusses four main types of visual neuroprosthesis approaches, including retinal approaches, lateral geniculate nucleus (LGN) approaches, optic nerve approaches, and cortical approaches, along with their constituent electrodes, metals, and stimulation patterns. Using existing neuroscience knowledge, the prospects of these devices are also highlighted.
