There are four types of tissues found in the human body connective, muscle, nervous, and epithelial.

I have Friedreich's ataxia, a neuromuscular disease.

It's a neuromuscular paralytic.

It's strange, but it's like deeper it's muscle, vein, nerve, bone.

And within this structure, you see these two pinkish layers, which are actually the muscle.

We're using a biological amplifier to amplify these nerve signals muscles.

And the first multi cellular organism was born. 600 MYA Nerves, and muscle, later evolved.

It's like 96 percent.

And I think it's no accident that we think this way.

Anything above your neck runs the risk of a complete neuromuscular shutdown.

This is one RBC,this is another one and they would bump into that endocardium.

The first one is harm care.

Nervousness

That's very unnerving.

Idiot!

Phosphine gas.

It's a neurotoxin.

Your neurolytic enzymes are at the same level they were a week ago.

GLaDOS You know what doesn't rhyme with compliance?

Insecure. Neurotic.

Are you some kind of neurologist?

ALS slowly destroys the nerves and muscles needed for moving your body.

And since I'm realistic, rather than grandiose,

And what I'm talking about are nerves.

But if you remove the arm, you simply anesthetize my arm, so you put an injection into my arm, anesthetize the brachial plexus, so the arm is numb, and there is no sensations coming in, if I now watch you being touched,

The amazing thing about this is that it's controlled by a really tiny set of neurons, about two dozen neurons that can produce a vast variety of different motor patterns, and the reason it can do this is that this little tiny ganglion in the crab is actually inundated by many, many neuromodulators.

We've also gone on with what was initially our primary population of people with above the elbow amputations.

This is foreign aid at its most heroic.

Hey. You really got a bad case of the nerves there, man.

It's like the water of the stream it never sits still.

I'm a neuroscientist.

It shows you these cells that process information.

Trigeminal headache? What? Trigeminal headache.

Your nerves, responsive.

Tonic for the nerves

What have you done to me? It has a hybrid nervous system.

That enables us to do two things.

I've never melded with a human before.

OMGGGGG FlNALLY... so much more to come, virtual reality, neural manipulation, visual dream emulation... neural coding, 'writing and re writing of memories', mental illnesses. So the first thing that you'll notice is that people have really strong opinions about this kind of work.

Imagine, with somebody who's lost their whole arm, we still have four major nerves that go down your arm.

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

You heard about neuromodulators earlier.

The photoreceptor cells are shown here at the top, and then the signals that are detected by the photoreceptors are transformed by various computations until finally that layer of cells at the bottom, the ganglion cells, relay the information to the brain, where we see that as perception.

And that's shown here in the the very light blue.
