It goes around the ventricle and, as I showed you in the beginning, also around the atrium. It goes all the way up and covers both the left and right side.

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.

51 Days

Evidence of an extradural hematoma.

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?

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.

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

I had retinal detachment five years ago.

In women, blood vessels grow every month, to build the lining of the uterus.

Blood flows through blood vessels.

It's gonna be going initially through a giant vessel.

And the capsules in her blood stream.

Blood runs in the veins.

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.

You know, where did these things come from?

The processing, of course, begins with the eyes.

It works.

also a work of fiction.

We can do this because tumor blood vessels are unlike normal, healthy vessels we see in other places of the body they're abnormal, they're very poorly constructed, and because of that, they're highly vulnerable to treatments that target them.

Next he has to pass a retinal scan.

Shut your mouth!

Incidences of leukaemia, tuberculosis and meningitis have dropped considerably.

like red blood cells.

(Laughter)

Subdural hematoma.

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 outer layer, this is the vasculature, which is incredible, around a human brain.

Thrombosis is the process of a thrombus forming.

End to end, that would form a line that would circle the earth twice.

I'll write it out again because I want to make sure we see clearly the difference between someone with compliant blood vessels and someone with non compliant vessels.

So, all these guys over here, these are the true capillaries.

So let's zoom in on one of them....Maybe we can zoom in right over here, that part of the artery.
