We're now going to turn it on.

First of all, these electrodes are noninvasive.

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

Высокоточные неполяризующиеся электроды для наземной геофизической разведки.

We can introduce electrodes within those circuits.

Sticking wires into the brain is obviously rather crude.

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

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

But look at all the electrodes around it.

So this looks something like this when it's in the brain.

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

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

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

In the 1950s, Olds and Milner put electrodes into the brain of a rat.

Subsequently, he allegedly was suspended by his arms, and electric shocks were applied to his fingers.

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

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

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

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

The patient then stays in the hospital for a few days, waiting to have a seizure with the electrodes constantly recording the activity inside his or her brain.

The town is home to Hindustan Electo Graphite (HEG), owning the largest graphite electrode plant in the world and is the largest industrial company in the entire state.

Photo electric cells and a microphone built into the sculpture catch all the variations in the fields of color, light intensity and sound intensity.

Volta's battery works at room temperature. It's fitted with solid electrodes and an electrolyte that's a solution of salt and water.

In the current perpendicular to plane (CPP) configuration, the current is passed perpendicular to the layers, and the electrodes are located on different sides of the superlattice.

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.

Olds and Milner put electrodes into the brain of a rat. And the rat would just keep pressing that bar thousands and thousands and thousands of times.

In order to find the exact location of the seizure onset, doctors embed electrodes directly into the patient's brain around the suspected seizure center.

We're going to place electrodes within the circuits that regulate your memory and cognitive function to see if we can turn up their activity.

The system's main components are a sample vial, source and destination vials, a capillary, electrodes, a high voltage power supply, a detector, and a data output and handling device.

We implanted electrodes in the fornix of patients with Alzheimer's disease, we turned it on, and we looked at what happens to glucose use in the brain.

Yes, now we want the patient to have a seizure so doctors can use the embedded electrodes to measure it and learn exactly where its origin was.

In the current in plane (CIP) geometry, the current flows along the layers, and the electrodes are located on one side of the structure.

We then put in the DBS electrodes and we wait for a month or a year, and the areas in red represent the areas where we increase glucose utilization.

So these three psychiatrists, after about two or three weeks of observation, laid him down on a table, connected his temples to a very small source of current.

And what they've done here is they've put electrodes in its ganglia and its brain and then a transmitter on top, and it's on a big computer tracking ball.

And what we tried with the pig was external electrodes on the skin, like you see in an emergency room, and I'm going to show you why they don't work very well.

So we wondered, can we place electrodes in this area of sadness and see if we can turn down the thermostat, can we turn down the activity, and what will be the consequence of that?

So this is what we did. We implanted electrodes in the fornix of patients with Alzheimer's disease, we turned it on, and we looked at what happens to glucose use in the brain.

Today I'll talk about a different approach, which is to put electrodes in different parts of the brain, and actually record the activity of individual nerve cells in the brain.

So if we could figure out what cells they are, we could maybe find new targets for which drugs could be designed or screened against, or maybe places where electrodes could be put in for people who have very severe disability.

And what they've done here is they've put electrodes in its ganglia and its brain and then a transmitter on top, and it's on a big computer tracking ball.

A technician will put the electrodes onto the scalp using a conductive gel or paste and usually after a procedure of preparing the scalp by light abrasion.

In 1951 he published a paper showing how he could display patterns of brain electrical activity on a cathode ray display screen using electrodes he devised specially for insertion into a living brain.

So we've placed electrodes within this circuit in an area of the brain called the fornix, which is the highway in and out of this memory circuit, with the idea to see if we can turn on this memory circuit, and whether that can, in turn, help these patients with Alzheimer's disease.
