Well the body works by starting a motor command in your brain, going down your spinal cord, out the nerves and to your periphery.

But when we were looking at the case sheets, what we found was, these people with the paralyzed phantom limbs, the original arm was paralyzed because of the peripheral nerve injury.

He had his arm amputated 10 years ago.

let's go to the brain and put something in the brain to record signals, or in the end of the peripheral nerve and record them there.

So in this case, they would turn into nerve cells.

legs without circulation, death from stroke, nerve damage.

So you think of alternative mechanical parts.

And what I'm talking about are nerves.

Liquidate. Abrogate. Quell.

Reproduction of pain is a positive test.

There's no damage outside.

No damage.

So this is really exciting for us, because now we have a portal, a portal, or a way to potentially give back sensation, so that he might feel what he touches with his prosthetic hand.

We're losing hull plating.

this process continues throughout our lives.

It's the process by which you recover from brain damage of various sorts, for instance, after a neurotrauma or a stroke. and it's also how you adapt to the fact that you now weight 20 pounds more after Christmas, and all your biomechanics are different, yet you still have to walk gracefully.

He has internal damage.

Head injury on the right,

Is there any risk of brain damage?

Now by noise, I do not mean sound.

But I have a message for the men here.

Okay, so everything around it is whole and intact.

So, the scores on the test should be consistent with things that we know about, development in general.

And it's very, very easy to see the damages on the bone structure.

You see here a little video.

There's physical damage to her chip.

If I'm damaged, we should know.

You know with any chip this damaged...

Apart from the messed up nerve ending.

The hardest thing to gauge right now. Is the extent of his neurocognitive deficits.

It's the process by which your brain is involved in learning, say a new skill, learning to ski or play Sudoku do things like that.

You can see a modern road, hardly 50 years old.

Shook us up a bit, but no damage.

Traumamatize, solar plexus.

But here in the US and actually here at Princeton University, there's a big study going on looking at the effect of sports related concussion.

I don't know.

People with spinal cord injuries,

Okay?

There's severe damage to the inner ear.

So there is the pattern that every one of them had, but they all were a little different too.

And the next morning, she knew if she could get to a nearby village where there was a foreign missionary, she would be saved.

If there were some people here, they would be broken

Internal injuries and...

Enterprise is taking heavy damage.

They're awful messy.
