The wires are surgically implanted in the same space that the photoreceptors once occupied, and they remain in physical contact with retinal cells to pass along electrical impulses to the visual cortex.<\/span><\/span><\/span><\/p>\n<p><span><span><span>The mice in the experiment had been genetically engineered to experience a progressive degradation of their photoreceptors, similar to what happens in people with retinitis pigmentosa and macular degeneration. <\/span><\/span><\/span><\/p>\n<p><span><span><span>Both diseases disrupt the eye\u2019s ability to pass sensory information on to the brain, and can lead to permanent vision impairment if not treated. Crucially, however, the rest of the eye and the brain\u2019s visual processing system remain intact, meaning that visual signals can still be processed if they reach the brain.<\/span><\/span><\/span><\/p>\n<p><span><span>The new photoreceptors are responsive to light in the green, blue, and near-ultraviolet spectrum, though their wires cannot grant mice color vision yet.
