Inside the pudendal canal, the nerve divides into branches, first giving off the inferior anal nerve, then the perineal nerve, before continuing as the dorsal nerve of the penis (in males) or the dorsal nerve of the clitoris (in females).

I had the nerve removed from my tooth.

And yes, it's a little nerve wracking.

I had the nerve removed from my tooth.

The sciatic nerve is the longest nerve in the human body.

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

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

This was a nerve that no one calculated would become such a big deal.

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

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

Galvani showed that a frog's legs twitched when he connected the lumbar nerve to a source of electrical current.

First, we cut away the nerve to his own muscle, then we took the arm nerves and just kind of had them shift down onto his chest and closed him up.

She didn't realize that she stepped on a sensitive nerve and aroused national questioning, almost a turmoil, against the credibility of Red Cross.

So you might say, 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.

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.

Instead of it being the case that that junction box in the spinal cord is just simple where one nerve connects with the next nerve by releasing these little brown packets of chemical information called neurotransmitters in a linear one on one fashion, in fact, what happens is the neurotransmitters spill out in three dimensions laterally, vertically, up and down in the spinal cord and they start interacting with other adjacent cells.

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.

The difference is that instead of the tip tap of Mr Chamberlain's umbrella, we have the verbose drip, drip, drip of the European Parliament's spineless, left oriented resolution.

At TEDMED, Sheila Nirenberg shows a bold way to create sight in people with certain kinds of blindness by hooking into the optic nerve and sending signals from a camera direct to the brain.

And here we deinnervate, or cut the nerve away, just from little segments of muscle and leave others alone that give us our up down signals and two others that will give us a hand open and close signal.

They want to compress the information they just want to send the changes, what's new in the image, and so on and that is how your eyeball is able to squeeze all that information down to your optic nerve, to send to the rest of the brain.

Our cameraman, who it turned out was a pretty nervous flyer at the best of times, actually asked the pilot, before we got on the plane, how long this flight would take, and the pilot Russian pilot completely deadpan, replied, Six hours if we live.

So just the same way that we were able to jump over the damaged circuitry in the retina to get to the retina's output cells, we can jump over the damaged circuitry in the cochlea to get the auditory nerve, or jump over damaged areas in the cortex, in the motor cortex, to bridge the gap produced by a stroke.

We must therefore make use of all the channels open to us politically, sound out all possibilities and so be as realistic as possible, banishing ideological preconception and the obstacles that may result from past experience or current differences. We must bring into play anything that may prove useful.
