Here you have a retina.

Developing retina, nose and fingers

This is a degeneration of the retina.

And the retina, of course, is a complex structure.

On the right side, my retina is perfectly symmetrical.

So from the retina you go onto visual cortex.

The retina chip extracts four different kinds of information.

So you have an image, a retina, and a brain.

The retina chip that we designed sits behind this lens here.

In other words, we're not literally replacing the components of the retina.

But when it's moving back and forth, the retina picks up these changes.

Well, the rod cells in your retina take over in low light conditions.

And vision of course starts in the retina but goes on in the brain.

Can we reconstruct what the retina was seeing from the responses from the firing patterns?

And we also did our first pass at making the Admin crisp on retina devices.

In the retina, there are two different types of light detecting cells rods and cones.

Images will be written directly to our retina, providing full immersion virtual reality, augmented real reality.

It makes contact with the retina in the rear which is covered with rods and cones.

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

These experiments led him to conclude the phenomenon was due to processes which lie behind the retina.

But on my left retina there is a bump, which is marked there by the red arrow.

You get all the new navigation, the new profiles. And it looks just gorgeous on that retina display.

This is high frequency laser, and it's enough with a fraction of a second to destroy the retina completely.

These are potent anti oxidants that will support your retina, your mitachondria, your brain cells and the removal of toxins.

Here are the cues of motion, the kinds of cues that you get on your retina when things are moving.

What you notice here is that these snapshots taken from the output of the retina chip are very sparse, right?

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

like form, color, depth, and motion, are transmitted to different areas of the visual cortex via different pathways from the retina.

It's been recently discovered that the last image seen by the victim before death is retained for several hours on the retina.

If I scan my retina through the horizontal plane that you see there in the little corner, what I get is the following.

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

And of course, the brain adds on a lot of information to what is going on in the signals that come from the retina.

An image comes in, goes through the set of equations, and out comes streams of electrical pulses, just like a normal retina would produce.

So what we did is we took a moment in time from these recordings and asked, what was the retina seeing at that moment?

So on the left is the encoder alone, and on the right is from an actual blind retina, so the encoder and the transducer.

When this first came out, it was just a really exciting thing, the idea that you even make a blind retina respond at all.

So, the simplistic model that the image on a retina goes directly into our brain and there's a little movie screen inside of our brain or something.

Light enters, hits the back of the retina, and is circulated, most of which is streamed to the very back of the brain, at the primary visual cortex.

So a completely blind retina, even one with no front end circuitry at all, no photoreceptors, can now send out normal signals, signals that the brain can understand.

And I'm going to show you a system that we designed to model the retina, which is a piece of brain that lines the inside of your eyeball.

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.

So when you look at something, like this image of this baby's face, it goes into your eye and it lands on your retina, on the front end cells here, the photoreceptors.

And the chip I'm going to show you a video that the silicon retina put out of its output when it was looking at Kareem Zaghloul, who's the student who designed this chip.

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.
