#### From the Ted Talk by Sheila Nirenberg: A prosthetic eye to treat blindness

## Unscramble the Blue Letters

Okay, so I just want to take a sentence or two to say something about the encoder and what it's doing, because it's really the key part and it's sort of interesting and kind of cool. I'm not sure "cool" is really the right word, but you know what I mean. So what it's doing is, it's rilncpaeg the retinal circuitry, really the guts of the retinal crirticuy, with a set of equations, a set of equations that we can imemelpnt on a chip. So it's just math. In other words, we're not llreitlay replacing the components of the retina. It's not like we're making a little mini-device for each of the different cell types. We've just abstracted what the retina's doing with a set of equations. And so, in a way, the equations are serving as sort of a codebook. An image comes in, goes through the set of equations, and out comes starmes of electrical psuels, just like a normal retina would produce.

Okay, so I just want to take a sentence or two to say something about the encoder and what it's doing, because it's really the key part and it's sort of interesting and kind of cool. I'm not sure "cool" is really the right word, but you know what I mean. So what it's doing is, it's replacing the retinal circuitry, really the guts of the retinal circuitry, with a set of equations, a set of equations that we can implement on a chip. So it's just math. In other words, we're not literally replacing the components of the retina. It's not like we're making a little mini-device for each of the different cell types. We've just abstracted what the retina's doing with a set of equations. And so, in a way, the equations are serving as sort of a codebook. An image comes in, goes through the set of equations, and out comes streams of electrical pulses, just like a normal retina would produce.
