To create a better retinal prosthesis, first crack some neural code

Making blind mice see: Researchers at Weill Cornell Medical College, including TEDMED 2011 speaker Sheila Nirenberg, have cracked the neural code for retina-to-brain communication to create a better prosthetic retina. Their study has just been published  in the Proceedings of the National Academy of Sciences. Read more about the breakthrough here, and check out her talk for the fascinating backstory.
