And these four types of information your optic nerve has about a million fibers in it, and 900,000 of those fibers send these four types of information.

The author of this paper explained that the crystal converts the vibration of ultrasound emitted outside the human body into electricity to drive a tiny transistor, which is directly attached to a nerve or muscle fibers, inside the device.

Brains only detect nerve impulses.

The headquarters for orgasm, along the spinal nerve, is something called the sacral nerve root, which is back here.

And yes, it's a little nerve wracking.

She had the nerve to speak out.

She had the nerve to speak out.

So they're spinning these tiny nano fibers of pure cellulose.

So silk fibers vary in their strength and also their extensibility.

It can also mean the fibers that grow from a head.

We've been able to see every single nerve.

When the sunlight comes through the window you see these little fibers.

What about the nerve that's going into this tumor?

Then I used fibers out of my jumper, which I held and stretched.

The success rate of the nerve transfers is very high.

In this simulation, each black dot is one nerve cell.

So what you can see here is that the five fibers have different behaviors.

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

When you look at this orb web, you're actually seeing many types of silk fibers.

There's quite a bit of variation within the fibers that an individual spider can make.

Sort of eavesdrop on the activity of nerve cells in the brain.

So here's an example of a nerve that has tumor surrounding it.

Stroke you normally think of as damage to the fibers, nothing you can do about it.

Here are stress strain curves generated by tensile testing five fibers made by the same spider.

And if we think of that let me put the picture up the fibers represent vulnerability.

Because we're putting a big fat nerve onto a little piece of muscle.

She said, Yes, if the sacral nerve is being oxygenated, you conceivably could.

Liver cells, nerve cells, pancreatic cells we still can't grow them even today.

You see the going down towards the fovea where the optic nerve begins.

This matrix self assembles, growing through and around the particles, making millions and millions of tiny fibers.

It has to go all over the world through fibers, through satellites, through all kinds of connections.

They're exposed to chemicals like chloropicrin, which was originally used as a nerve gas.

You can see multiple fibers coming out of the spinnerets, because each spinneret has many spigots on it.

You follow instructions on Nerve and you should end up on Babble, which we did.

The actual nerve supplying the arm was severed, was cut, by say, a motorcycle accident.

There's a lot of information in those nerve signals, and we wanted to get more.

Specifically, if you look on the vertical axis, that's stress. If you look at the maximum stress value for each of these fibers, you can see that there's a lot of variation, and in fact dragline, or major ampullate silk, is the strongest of these fibers.

So all of those colored lines correspond to bunches of axons, the fibers that join cell bodies to synapses.

That takes a little bit of nerve, and, darn it, once in a while you fail.

On top of that, these battery free sensors can be used to stimulate nerve and muscle.

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

So I got the teddy bear and I said, Do you mind if I pull out one of your fibers?

The Bible says you cannot wear clothes made of mixed fibers, so I thought, Sounds strange, but I'll try it.

And we take the nerve away from your chest muscle and let these nerves grow into it.

You can imagine that then maybe you can use a pure protein to guide light, and so we've made optical fibers.
