It's constantly changing its structure based on our experiences, right? So that principle of error-driven learning happens, we know, in the motor system, for instance.

And even if it's not tied to any particular context, if I'm shooting that basketball, my brain, there's a new brain area called the cerebellum that generates an internal model of what I just did and a prediction of where that ball is going to go into.

And if the ball doesn't go into the right place or if it doesn't feel right as I'm shooting the ball, my brain will tweak the memory so that I will be better at it. In fact, I actually just saw a talk yesterday suggesting that sleep is a big part of that whole dynamic, that during REM sleep when we're dreaming, for instance,

what may be going on is at least one of the things that goes on is that the motor system is really tuning itself up so that you get these better movements and better hand-eye coordination based on the skills you've tried to learn early in the day. And in fact, that seems to be why dogs, for instance, like move their legs at night when they're asleep.

It's not necessarily that they're having subconscious dream as much as, their brain is basically just tuning up the motor system. And in fact, those movements come from a very primitive area of the brain.

Can you say the difference between the two kinds of novelty again? Sorry, I missed that.

So it's a great point. I think that novelty doesn't have to be something that is New per se. So the brain's constantly trying to generate predictions about what's going to happen. And this is just based on the way the brain's wired.

I mean, I will pour people the details of thalamocortical interactions, but the basic gist of it is that when you're in a completely new place, your brain has no predictions it can make, right? Or it's making very weak predictions based on similar places you've been.
