Well, there's two parts of it, right? So there's this fight or flight response, which is we tend to associate with the feeling of fear. And so that's our heart racing, our body is mobilizing us to move. And so we're getting our adrenalines pumping through our veins and we have a burst of neuromodulator called noradrenaline in our brains.

And that's going to promote plasticity for this moment when I was scared for whatever it happens to be. And so that's the brain saying, hey, this is biologically important. But we also have the anxiety of how things could happen.

So in other words, if you're a mouse and you're running around and all of a sudden you see a cat and the cat starts chasing you, you get this big fight or flight response. But now you could be a mouse and you don't know where the cat is, but it's somewhere out there and any moment it could jump out.

Now you're under stress and anxiety, and that's associated with all these release of these stress hormones. And the way these stress hormones tend to work is they don't just enhance memory for that moment where the bad thing happened, but a lot of the things leading up to it. And we think the reason for that, I think it makes sense, is

If you're a cave person and you go into a cave and you get attacked by a saber-tooth tiger, you don't want to just know that you got attacked by the saber-tooth tiger. You want to know where that cave was and how to avoid it in the future. So you want to learn all the things that led up to that point.
