Blind Mice Given Sight After Device Cracks Retinal Code - Bloomberg: Visual Equations
Nirenberg and co-author Chethan Pandarinath first monitored healthy eyes to determine the set of equations that translate light received by the retina into something the brain can understand. Then, they used special glasses to create a similar code and deliver it to the eye, which had been engineered to contain light-sensitive proteins. The cells received the code through the light sensitive proteins and fired electric impulses, which the brain could interpret as images.
