| Artificial Retina |
"Two researchers in the US have taken a huge step forward in
developing technology to help blind people see: they have made an
artificial retina that
restored normal vision in blind mice. And they have already worked out a way to make a similar device for monkeys, which they hope to quickly redesign and
test for human use," reports
Medical News Today. "Artificial retinas are not a new invention; however, the ones produced
so far only produce rough visual fields where the user sees spots and
edges of light to help
them navigate. But the one Sheila Nirenberg and Chethan Pandarinath at Weill Cornell
Medical College in New York have developed allows animals to detect
facial features and
track moving images."

Bloomberg News reports that "in research described today in the
Proceedings of the National
Academy of Sciences, scientists cracked the code the retina uses
to communicate with the brain...Once the researchers determined the code the mouse retina
used to communicate with the brain, they were able to mimic it
with electric-signal sending glasses, Nirenberg said. Previous
prosthetics have used less-specific stimulation and proved
inherently limited as a result, she said."
