So I've been collaborating with a group at Mass General Hospital to record from people with epilepsy, and they have to have an operation for people who are drug resistant, to be able to find out where it starts in the cortex, where it is initiated, where the seizure starts.

And then to go in, you have to go in and record simultaneously from a lot of parts of the cortex for weeks until you find out where it is. And then you go in and you try to take it out. And often that helps. very, very invasive, but for two weeks we have access to all those neurons in that cortex that are being recorded from constantly.

And so I've used, I started out because I was interested in sleep and I wanted to understand what happens in the cortex of a human during sleep. But then we realized that, you know, you can also figure, you know, people who have these debilitating problems with seizures, You know, they're there for two weeks and they have nothing to do.

So they just love the fact that scientists are interested in helping them and, you know, teaching them things and finding out where in the cortex things are happening when they learn something. This is a goldmine. It's unbelievable. And I've learned things from humans that I could have never gotten from any other species. Amazing. Obviously, language is one of them.

But there are other things in sleep that we've discovered. having to do with traveling waves. There are circular traveling waves that go on during sleep, which is astonishing. Nobody ever really saw that before.

This is non-REM sleep. This is a jargon. This is during intermediate,
