Current Issues Merging neuroplasticity and neuroprostheses (Nature reviews Neuroscience 6, 2005) Retina Cortex Optic nerve “In two common causes of blindness, retinitis pigmentosa and age-related macular degeneration (ARMD), there is a relatively selective degeneration of the photoreceptor layer of the retina. On the other hand, ganglion cells within the inner retinal layers survive in large numbers and respond to electrical simulation even in advanced stages of the diseases.”
