So we release adrenaline and cortisol.

So our hearts start to pound, our pupils dilate, our airways open up.

We shunt blood to our big muscles for running and jumping and away from that itty bitty muscle that holds your bladder closed so you may pee your pants, but there's no judgment, right?

And so you're ready to either fight the bear or run from the bear.

Yes.

But if you were to think about it, fighting a bear would not seem like a good idea, would it?

No.

And that's why the amygdala actually sends neurons.

It sends projections to the prefrontal cortexes.

That's the part of the brain that sits right here behind the forehead.

And this is the part that's responsible for judgment, impulse control, executive functioning.

And it turns it way down.

Because the last thing you want, if you're in a forest and there's a bear, is some impulse control getting in the way of survival.

That's exactly right.

Now,

That is what we call the fight or flight response.

Or you're absolutely right.

The other thing that can happen is that you can freeze.

So there's a fight, flight or freeze.

And then the other thing that happens, and especially it's more common with women, is that you can fawn.
