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

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.

So let me start in on that problem.

Yeah, it's called Retinitis Pigmentosa.

Colors are flavonoids and polyphenols.

It works.

I found out the the following.

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.

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

But fingerprints and retinas are unique.

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

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.

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.

In metaphase I let me just copy and paste what I've already done the nuclear envelope is now gone.

They receive comprehensive eye exams.

51 Days

So that's called the visceral pericardium.

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

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

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

It'll just bake your retinas.

And then, when the heart is ready to pump it back out, it goes into this artery, and the name of it is the aorta.

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.

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

This vessel I'm gonna label let's say here, as the Aorta.

I ended up with blunt chest trauma.

There are actually separate names for the two layers.

I had retinal detachment five years ago.

I just wanted to say something about the standard method.

What's happening between these two, time like here, is that blood is actually squeezing out because the pulmonic and aortic valves just opened, blood is squeezing out and going to the whole body.

So these two veins, the superior vena cava and the inferior vena cava, are dragging the blood back to the heart, and, generally speaking, these are all considered, of course, veins.

So blood is headed towards the lungs, going first through the trunk, and of course after the trunk, there is left and right I write that up here pulmonary arteries are next.

And before I left the hospital, after a year of being hospitalized,

His vitals are spiking.

Now you can actually see the layers of the heart, the endocardium, myocardium and pericardium.

So ischemia is deprivation of blood flow and oxygen downstream from this right over there.

The processing, of course, begins with the eyes.

Let's say this toe right here.

Coronary vessels So, coronary artery and vein.

And so when people talk about arteries getting blocked or getting clogged, they're talking about the coronary arteries.

And the veins actually drain into a spot , directly into the right atrium.

My name is Papusay.

In that gap you might have a little bit of fluid, but it's not actually cells. I guess that's the biggest point, it's not cells, it's just a little bit of fluid.

We have a layer called the pericardium.
