Here the red is the positive terminal and I'm going to put that over your left forehead and

The block is the negative terminal and I'm going to put that over your right forehead and the electricity is going to run

For the long time through my head from the positive to the negative. This is me in the laboratory of Morone Bixon

He's a professor of biomedical engineering at the city college of New York and he's attaching electrodes to my forehead

Professor Bixon's about to run a couple milliamps of electrical current through my skull

Great your head is the circuit because you think about it right that the the electricity will arrive at one sponge and

After that is just your head so it has nowhere to go it has to cross into your head

Flow through your head and then you have a worried look on your face

That did really my anxiety when I thought about it that way they

Here's one here's a wire here's another wire

Let's just go through those wires and the thing that it's going to go through is is me my friend

Do you want to feel it on your arm first sure?

Professor Bixon first became intrigued by brain stimulation when he was a student and he was studying epilepsy

And he found out that a seizure is like an electrical storm in the brain that idea fascinated him

Nowadays professor Bixon designs medical devices and some of those devices are battery-powered caps that you can wear on your head

The caps give off about as much electrical current as a nine volt battery in some cases it could look like a swimming cap

With little knobs in it and those knobs press on to the scalp

Each one of those knobs has a wire coming out of it that connects to a little computer and

By controlling how much current is sent to each knob you can direct the electrical energy to different parts of the brain

He's hoping that using this kind of cap might do things like help people recover faster from a stroke

So really our mission is to reduce human suffering with technology and we work with all kinds of technology
