Graphite.

It's a problem with the graphite, sir.

Now, here with 256 electrodes.

Your electrodes came off last night.

OK, now, these are my sprinting legs, made of carbon graphite,

We can introduce electrodes within those circuits.

First of all, these electrodes are noninvasive.

But look at all the electrodes around it.

They put electrodes or sensors on my head.

I'll be back later to attach your electrodes.

Miss baum's electrodes must have slipped off again.

This right here is carbon, and this is in the...in its graphite form

Here. On one side, you have mercuric oxide and graphite from your brake pads.

We got all these electrodes now, arrays are being developed.

Oh, we'll only be using two small electrodes on him.

So what we're doing is placing these electrodes throughout the brain.

So we went ahead and implanted electrodes in patients with depression.

Olds and Milner put electrodes into the brain of a rat.

liquid metals for both electrodes and a molten salt for the electrolyte.

We're going to see electrodes being placed for many disorders of the brain.

We copy this in the lab by outfitting cell culture systems with electrodes.

And what we tried with the pig was external electrodes on the skin,

These brain electrodes can tell us more than just where the seizures happen.

When triggered, the electrodes will send a charge converting the chemlal into gas.

I mention, you can actually map the brain and understand these are actually electrodes that were implanted and you can localize where exactly is the electrodes are touching in the brain.

The electrodes are turned off now, and you can see that she has tremor.

So one of areas that they want to implant electrodes, we find it here.

Now, this is Dr. Lene Harbott applying electrodes to the head of John Morton.

Most people don't like the electrodes first time out. Makes 'em feel like frankenstein.

It's fitted with solid electrodes and an electrolyte that's a solution of salt and water.

And the current passing between the electrodes generates enough heat to keep it at temperature.

These electrodes act like mini pacemakers to get the cells to contract in the lab.

Using a grid the size of your thumb, with 32 electrodes on the surface of his brain,

And we can use electrodes or antennae to pick that up and tell the arm to move.

Using a grid the size of your thumb, with 32 electrodes on the surface of his brain,

Two players who are being scanned using EEG electrodes are going to bargain over one to six dollars.

After doctors are sure where the seizures come from in the brain, they can take the electrodes out.

This electrode here, called the gate, controls the flow of current from the source to the drain these two electrodes.

Based on where the doctors place the electrodes in the brain, we can ask questions about what the brain does.

Then with a brush I smudge the graphite for a more even finish. I reinforce the shadow in the vicinity of the drop, and then smudge it.

You can see the movements on his chest, and those little hash marks are where we put our antennae, or electrodes.

And that's fortunate, because we can put two electrodes on your palm and measure the change in skin resistance produced by sweating.

Galvani's approach of probing the nervous system with electrodes has remained state of the art until today, despite a number of drawbacks.

Again, it's got technology it's got electrodes going into its left and right hemispheres it's got a camera on top of its head.

She's putting electrodes on his head so that we can monitor the electrical activity in John's brain as he races around the track.
