This is a degeneration of the retina.

Where does it go inside the body?

So it goes in and it stays there.

Every patient we do has an absolutely bespoke implant.

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.

And now today we have the modern multi channel cochlear implant, which is an outpatient procedure.

The implant contains no valves and is placed completely within the eye without sutures.

I had retinal detachment five years ago.

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

Doyle commands Carver to find his way to Doyle's position, so that the implant can be removed.

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

So for whatever reason, this implant is not successfully stimulating auditory cortices during melody perception.

But there's millions of deaf people in the world, and the Cochlear implant has given hearing to thousands of deaf people now.

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.

This implant is not transmitting the quality of music that usually provides things like warmth.

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.

And not long after I got my cochlear implant, I started learning how to play piano.

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?

So if we had to design a perfect cochlear implant, what we would try to do is target it to be able to allow music transmission.

Veterinary implant TR BioSurgical has commercialized a new implant specifically for veterinary medicine, called TR ClarifEYE.

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.
