The EEG Headset Is a Very Slow, Wavy Curve

The EEG is what we call the signal, the electro-emselfic ion that gets constantly outside the brain. If you put a little bit of gel on the outside of it and you can put this onto your head and you're going to be able to record your own brain activity. And if you did that, you would probably something compared to what we just saw. It would look like nothing. But then when you close your eyes, you get to see this oscillation that occurs. That's really, really significantly different than when your eyes are open.
