You see the going down towards the fovea where the optic nerve begins.

So, a solution to the problem, then, would be to build a device that could mimic the actions of that front end circuitry and send signals to the retina's output cells, and they can go back to doing their normal job of sending signals to the brain.

Yeah, it's called Retinitis Pigmentosa.

So let me start in on that problem.

Colors are flavonoids and polyphenols.

It's a very difficult procedure, but it is possible to photograph this image.

But fingerprints and retinas are unique.

They receive comprehensive eye exams.

This is another example of patient specific stem cells that were engineered from someone with retinitis pigmentosa.

They'll be so small, they'll be embedded in our clothing, in our environment.

I found out the the following.

And, how come you can't detect colors when it's dark?

So this is basically multiplexing in time.

This computer network is, as it were, the nervous system of the company.

little bit and show you how a normal retina works first so you can see the problem that we were trying to solve.

It'll just bake your retinas.

Instead of doing this in software, or doing those kinds of algorithms, we went and talked to neurobiologists who have actually reverse engineered that piece of brain that's called the retina.

But these are essentially externalized stomachs and lungs.

So what happens when a person gets a retinal degenerative disease like macular degeneration?

I had retinal detachment five years ago.

All of these objects flow outwards and they leave trails, or blur lines, on your retina.

It brings the light into focus at just the right spot, and then you have your retinal nerves and you have two eyes so can see in stereoscopic vision.

Here's one that's in prototyping by Medtronic that's smaller than a penny.

So it consists of two parts, what we call an encoder and a transducer.

I just wanted to say something about the standard method.

So we are really duplicating the kind of signals that you have on the optic nerve.

The processing, of course, begins with the eyes.

It works.

also a work of fiction.

And this is the same thing you see when people compress video to send they want to make it very sparse, because that file is smaller.

Next he has to pass a retinal scan.

So this is how close your mental experience and the activity of the neurons in the retina, which is a part of the brain located in the eyeball, or, for that matter, a sheet of visual cortex.

And this is what the retina is doing, and it's doing it just with the circuitry, and how this network of neurons that are interacting in there, which we've captured on the chip.

Carmen Puliafito, who developed a laser scanner of the retina,

So it's just math.

Light perception happens in a paper thin layer of cells, called the retina, that covers the back of your eyeball.

We're going to take these blue light photosensors and install them on a layer of cells in the middle of the retina in the back of the eye and convert them into a camera just like installing solar cells all over those neurons to make them light sensitive.

I'm not sure cool is really the right word, but you know what I mean.

When you look at a painting that you qualify as beautiful the activity goes through the retina, the optic pathways, to the primary optic cortex to the specialized areas that are specialized for detecting and processing bodies, and then goes to the medial orbital frontal cortex, somehow, and you experience beauty.

That's very unnerving.

Idiot!
