It's that it goes into a completely different state, and memory consolidation is just one of those things that happens when you're fall asleep. And of course, there's dreams and so forth. We don't fully appreciate or understand exactly how all the different sleep stages work together. But exercises are particularly important part of getting the motor system tuned up.

And it's thought that the REM, rapid eye movement sleep, may be involved in that. So that's yet another part of the sleep. stages. You go through, you go back and forth between dream sleep and the slow-wave sleep, back and forth, back and forth during the night. And then when you wake up, you're in the REM stage, more and more REM, more and more REM. But, you know, that's all observation.

But, you know, as a scientist, what you want to do is perturb the system and see if you can – maybe if you had more sleep spindles, maybe you'd be able to remember things better. So it turns out Sarah Mednick, who's at UC Irvine, did this fantastic experiment. So it turns out there's a drug called zolpidem, which – It goes by the name Ambien. You may have some experience with that.

That's right. A lot of people take it in order to sleep. Okay. Well, it turns out that it causes more sleep spindles. Really? Yeah. It doubles the number of sleep spindles. If you take the drug... You take the drug... after you've done the learning, right? You do the learning at night and then you take the drug and you have twice as many spindles.

You wake up in the morning, you can remember twice as much.

Yes, yeah, no, it consolidates it. I mean, that's the point.

Okay, here's the downside. Okay, so people who take the drug, say if you're going to Europe and you take it and then you sleep really soundly, but often you... You find yourself in the hotel room and you completely have no clue, you have no memory of how you got there.
