Visual Prostheses: Optic Nerve Stimulation

This lecture discusses visual prostheses using optic nerve stimulation as an alternative for blind patients with functional retinal ganglion cells. It covers implantable peripheral nervous system interfaces, cuff electrodes, and optic nerve-induced phosphenes. The presentation explores the challenges of achieving focal stimulation and the potential of more selective electrodes. Additionally, it delves into the design and performance of optic nerve stimulation using intraneural electrodes, highlighting the 3D arrangement for targeting the visual field. The lecture concludes with insights on the advantages and disadvantages of different target sites for visual prostheses along the early visual pathway.
