What happens to my brain when I sleep?

What happens to the brain when you go to sleep. It is really complicated. When the brain is in rapid eyeball movement to dreaming sleep, a lot of it is acting in the same way as it is during wakefulness. It is really hard to say. Ten years ago, so we're talking about mid-nineties, we would say it is rather like the brain shuts down, rather like putting a night-cap on the head, the brainwaves become much slower and eventuallly the whole brain is generating this big, large and slow waves. Now we know that is not true. There's just a lot of stuff going on.
