As you look at this page, your eyes are doing a remarkable thing.
A stream of light from the words and pictures is bouncing into the eyeball and falling onto photoreceptor cells on the retina. This visual information is passed on to output cells and then transmitted to the brain as a kind of code, where it is reconstructed to make up the letters in this sentence you are reading right now.
Degenerative eye diseases, however, can wreak havoc on this process, says neuroscientist Sheila Nirenberg of Weill Medical College at Cornell University. When they damage the retina, the image in front of you never gets further than the eyeball; the chain is broken.
That’s what makes the technology that Nirenberg has built rather remarkable. She has found a way to transmit a visual code directly to the brain, bypassing damaged cells in the eye. In other words, she can help the blind see again.
Neuroscientist Sheila Nirenberg of Weill Medical College at Cornell University is researching the effects degenerative eye diseases have on the process of transmitting information from the eye to the brain. From her research, she has developed technology to help the visual information in front of an eye containing a damaged retina, that isn’t being transmitted, bypass the damaged retina cells, and instead successfully reach the brain where it can be processed. Her technology is definitely considered a breakthrough in the area of curing blindness. The video below explains the technology in greater detail, and how Nirenberg was turned on to the idea.
