Blind Mice Regain Sight, Scientists Crack Retina Code

| by Michael Allen

A study released today by the Proceedings of the National Academy of Sciences claims that blind mice had their vision restored with a device that helps diseased retinas send signals to the brain, reports Bloomberg News.

According to the study, scientists located the code that the mouse retina uses to communicate with the brain. They were able to mimic it with electric-signal sending glasses.

Sheila Nirenberg, a neuroscientist at Weill Cornell Medical College in New York and the study’s lead author, said: “What this shows is that we have the essential ingredients to make a very effective prosthetic."

Researchers haven’t yet tested the technology on humans, but are planning to test it on monkeys.
