Scientists Reverse Engineer Animal Brains To Create Bionic Prosthetic Eyes
MrSeb writes "Utilizing neuroscience, gene therapy, and optogenetics, a pair of researchers from Cornell University have created a bionic prosthetic eye that can restore almost-normal vision to animals blinded by destroyed retinas. Prosthetic eyes have been created before, but for the most part these have been dumb prosthetics — chips that wire themselves into the ganglion cells behind the retina, which are the interface between the retina and optic nerve. These chips receive optical stimuli (via a CMOS sensor, for example), which they transmit as electrical signals to the ganglion cells. These prosthetic eyes can produce a low-resolution grayscale field that the brain can then interpret — which is probably better than being completely blind — but they don't actually restore sight. The Cornell prosthetic eye however, developed by Sheila Nirenberg and Chethan Pandarinath, is a much closer analog to a real eye, almost completely restoring sight in mice — and within 1 or 2 years, humans (PDF)."
Art and science constantly seem to follow and build upon the advances of each other. Great ideas... the results of imagineering or "the big, fantastic think," seem to emerge in one to support or catalyze forward motion in the other.
While I'm not eager to incorporate bioengineering into my person, I also am not a position where my quality of life would be marginally improved by such. I'm confident that my perspective is colored by my current capabilities and would necessarily change if my capabilities were different. This is the stuff of science fiction... and science.
Shouldn't we have to invent the VISOR before we start creating prosthetic eyes?

I would like mine with a HUD, infrared/night vision, and 50x zoom.
sudo make me a sandwich
Now tell me how we could have simulated this and tested it in a computer model, PETA guys.

My jaw dropped in amazement. The fact the technique is extensible to other sensory and brain malfunctions seems to be just icing on the cake.

He slipped up a single number by a factor of one? For Joe Biden that's a very good day. And you didn't even bring up the part where he gave BJs to his Hollywood masters later in the day. You're just terrible at trolling.

In my case, my eye was injured in a bad car wreck 20 years ago (the entire eye orbit was shattered, the muscles were damaged, and the optic nerve was nearly severed). The eye itself is still close to 20/20 vision, but is out of alignment with the other eye, and most of the signal doesn't get through (blurry and strange vision). Now there will finally be a way for me to have stereo vision once again (I would prefer my old eye working again, but I'll take what I can get). For the first time in 20 years, I won't be embarrassed to shoot hoops, play tennis, or play volleyball ;-).

I want the eyes that Judge Dredd got when his eyes got damaged.
Ability to see from deep in the microwave to high UV.
Micro and telescopic lens function
Access to information (like Google's glasses)

My wife does. She also went to a Star Trek convention this year and left at home to watch our child! I think I have been assimilated!

Can I get one right on the back of my head?
Oh, and one on each foot, facing upwards. Just in case.
You are welcome on my lawn.
I don't want to be all /crymore PETA but; "vision to animals blinded by destroyed retinas." Is really a downer for me on this. When we as a race can advance our civilization without the need to purposely harm other subjugated species on this planet for our betterment as nothing more than lab medium, then I'll be impressed.

That was my first thought.
Okay. These researchers figured out the coding sequence for the retina/nerve interface. Basically they figured out TCP/IP for your eyes. And they designed an "honest" retina that mimics a regular retina.
I'll stop there for a moment and say WOW. Nicely done, absolutely thoroughly amazing.
But then let's up the ante and have the circuitry they are using employ infrared detection. Not too difficult to do, we've been making these kinds of devices for many decades. And the same goes for a x50 zoom. Easy peasy.
A HUD display would be possible too. Watch the TED lecture at the bottom of the article. This lady KNOWS THE ENCODING that your eyes use! She can actually take the pulses transmitted to the brain and solve them backwards to see what you were looking at! With that kind of knowledge making something that transmits a generated image would be simple.
This is a *gigantic* breakthrough.

rediculous.
Ohhh excuses excuses excuses, you leftists and your lying double standards make me want to throw up.
I'm sorry you feel that way about us. Here, you can borrow my "NPR Donor" tote-bag to catch the vomit. Then just wash it with an environmentally friendly phosphate free soap, and return it to me when you can.
Every story on slashdot should being with "Utilizing science, ...."
Now you can see what I mean!
-- By all means let's be open-minded, but not so open-minded that our brains drop out.
What are you talking about? She was given three rescued and sightless mice to work with, who's tails had been cruelly shortened by their previous caretaker (the bitter spouse of a guy working at a meat processing facility). Now she was able to restore sight to them, and you should see how they run now! See how they run!
GWB was an imbecile, much like you, and he was ridiculed for it, much like you should be.
Not one of you can even consider the suffering of the animals in this 'research', can you. Not one of you is capable of empathy, yet no doubt consider yourselves to be really 'mature' and 'grown up'.
"animals blinded by destroyed retinas".
Doesn't that sound nice and 'technical'. Try being the innocent victim who is being tortured. Do you know what pain is? Ever experienced it?
What makes you think your life is worth more than that of a mouse? Do mice torture billions of human beings to death every year? Isn't it the other way round? But human beings are the 'worthy' ones, and mice are nothing, apparently.
IF this technology ever works in humans, it will be SOLELY because of HUMAN experiments, the first of which will FAIL. The researchers will learn from the HUMAN experiments, and gradually improve it, always reminding us that it's only "because of the animal experiments" that they could do the human experiments - which is untrue. It's true from a legal standpoint - because most people are too stupid to investigate the fraud that is vivisection, they believe that it works, and predicts human outcomes (which it does not), so they therefore think that these aren't human experiments, they're 'clinical trials', but they ARE human experiments. 92% of drugs which pass animal experiments FAIL human experiments, AKA 'clinical trials'. What does that tell you about the predictive qualities of animal experiments.
LOL at the idiot who's going to say "What's the solution then? To experiment on humans?"
They're ALREADY experimenting on humans! With every drug and every new medical procedure that they've already tried in animals (completely without any merit), when they test them on humans, they ARE experimenting on humans, because they don't know the result, and 92% of the drugs will FAIL. Does it need to be any clearer than that?
The monkey used was also a rescue who has two siblings, one who cannot hear, and one who cannot make vocal noise.
Don't know something? Look it up. Still don't know? Then ask.
I think that was actually a agricultural workers wife who took retribution on the poor little blind creatures for giver her such a fright.
Yes, and Rob Malda's penis is still 10x bigger than your brain.
I like your signature. How did you come up with it??
For a while on every story was a post by someone asking what a word in the summary was and why was that word not explained.
In each case it would have been easier for the person to look it up rather than ask.
Don't know something? Look it up. Still don't know? Then ask.
That would be impressive. It would be almost as impressive as you living without the need to purposely harm other subjugated species on this planet for you betterment.
Zombie movies have ruined me for life. I read the headline and now all I can think about is a bunch of scientist shuffling through a lab screaming "BRAINS!!!".
