This is a degeneration of the retina.

Stage 5 is total retinal detachment.

I have permanent retinal damage

And so the encoder does just what I was saying it mimics the actions of the front end circuitry so it takes images in and converts them into the retina's code.

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 from the retina you go onto visual cortex.

We've just abstracted what the retina's doing with a set of equations.

I had retinal detachment five years ago.

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

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.

There are also several neuroprosthetic devices that aim to restore vision, including retinal implants.

51 Days Developing retina, nose and fingers

In retinal separation, the retina detaches from the back of the eyeball.

But that means that retinas in your eyes are not catching the light, either.

Stem cell derived retinal transplants, now in a research phase, may one day restore vision, or part vision, to millions of patients with retinal diseases worldwide.

The optic nerve is composed of retinal ganglion cell axons and glial cells.

In 2006, the Swede struggled through the season after suffering an eye injury early in the season.

He sees with a combination of the retina, the brain, the eyes, and light and many other factors which I needn't go into.

On the positive side, we now have sunscreen for your retinas.

And the other thing is they're working on artificial retinas for the blind.

This experience taught me to empathize more with my patients, and especially those with retinal diseases.

This mechanism is used, for example, with rhodopsin in retina cells to compensate for exposure to bright light.

About 10 of all retinal ganglion cells are parasol cells, and these cells are part of the magnocellular pathway.

The temporal hem retina, on the other hand, stays on the same side.

Carmen Puliafito, who developed a laser scanner of the retina, I found out the the following.

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

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

Then, the retinas in your eyes catch the light reflection for your brain to interpret into the image of an apple.

The instant you stepped outside, specialized receptors in your retina in the back of the eye would kick off an avalanche of neurological activity.

Completely different meanings, giving rise to the exact same retinal information.

Artificial retinas, the ability to put these arrays on the back of the eyeball and allow the blind to see.

Overexpression of VEGF can cause vascular disease in the retina of the eye and other parts of the body.

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

In many forms of blindness, like retinitis pigmentosa, or macular degeneration, the photoreceptor cells have atrophied or been destroyed.

Okay, so let me back up a little bit and show you how a normal retina works first so you can see the problem that we were trying to solve.

On the following day, 3 August 1993, she was operated on, for a detached retina, at the General University Hospital.

We kind of changed the simple digital camera into a retinal camera, and then every patient gets their teleconsultation with a doctor.

But sometime ago, through the help of an opthamologist colleague of mine, Carmen Puliafito, who developed a laser scanner of the retina, I found out the the following.

The judge considered that neither the blow from the lemon nor the consequence of a detached retina had been proved.

And then the transducer then makes the output cells send the code on up to the brain, and the result is a retinal prosthetic that can produce normal retinal output.

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

51 Days 52 Days Developing retina, nose and fingers The fetus' continual movement in the womb is necessary for muscular and skeletal growth.

Then what happens is the retinal circuitry, the middle part, goes to work on it, and what it does is it performs operations on it, it extracts information from it, and it converts that information into a code.

As a result of examinations by the prison doctor on 14 November 1988, aphykia (the absence of the lens of the eye) and ablatio retinae (detachment of the retina) were found.

Heart disease, stroke, diabetes, spinal cord injury, muscular dystrophy, retinal eye diseases are any of these conditions relevant, personally, to you?
