But I can't put in an electrode and say, Go there.

So to create an electrical field, we have to have a cathode and an anode.

In the blue wire, we see what's called a deep brain electrode.

You may or may not have noticed that I'm wearing a tiny electrode on my forehead.

But the basic idea is that the neurosurgeon implants in the brain an electrode and sends some excitation to that electrode, and this is extremely important for many, many problems, like Parkinson, tremor, depression or, or, or other problems.

And if you trigger, if you stimulate with an electrode, the precise spot, you will trigger an orgasm.

But on the other side, where the anode is, you'll have a positive charge, because this is where oxidation is taking place.

And this forces magnesium to de alloy and return to the upper electrode, restoring the initial constitution of the battery.

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

And in order to do that, we actually, in order to know where to implant the electrode, and where exactly to go.

You see the electrode going through the skull into the brain and resting there, and we can place this really anywhere in the brain.

And Whewell not only coined the term scientist, as well as the words anode, cathode and ion, but spearheaded international big science with his global research on the tides.

Again, we are making holes in the skull about the size of a dime, putting an electrode in, and then this electrode is completely underneath the skin down to a pacemaker in the chest, and with a remote control very much like a television remote control, we can adjust how much electricity we deliver to these areas of the brain.

For example, we can connect the recording electrode to a cursor on a screen and have the patient move the cursor left or right just by thinking of things.

One part of the virus grabs a carbon nanotube, the other part of the virus has a sequence that can grow an electrode material for a battery, and then it wires itself to the current collector.

We know that if you stimulate the temporal lobe, you can produce a feeling of out of body experiences, near death experiences, which you can do by just touching an electrode to the temporal lobe there.

We want to develop these little tiny capsules about the size of a piece of risotto that we can put into the muscles and telemeter out the EMG signals, so that it's not worrying about electrode contact.

Gaby Maimon, who's now at Rockefeller, developed, and it's basically a flight simulator but under conditions where you actually can stick an electrode in the brain of the fly and record from a genetically identified neuron in the fly's brain.

lately, in the last couple of weeks, people have seen that there's an enzyme called hydrogenase that's able to evolve hydrogen from proton and electrons, and is able to take hydrogen up basically what's happening in a fuel cell, in the anode of a fuel cell and in a reversible fuel cell.
