So let's talk about sound for a minute because all sound comes from and is perceived by us through a series of processes in the brain.
And most of these are in the higher brain region, but screams are different.
They happen in the lower brain region.
And it's a very interesting thing.
It kind of lives in its own, as far as like humans making sound, lives in its own area.
It's very distinct from all the other sounds we make.
So for screams and some involuntary vocalizations, but really screams, the sound production takes a different and like you said, a much faster path.
The signal starts in the limbic system and it skips that higher brain processing.
It happens in the amygdala, basically.
The emotional stimulus that the amygdala is all about just sends a scream signal.
It's sort of like a direct path, like an express train through that brain stem to all the anatomy that you were talking about and the neck junk.
And that scream just comes out immediately.
And the craziest part is our body actually picks up on this immediately.
before our ears and brain can even process what we've just heard.
And I mean, that's why when somebody screams like a blood curdling scream out in public, you're you're instantly reacting.
You don't hear that and then decide like, well, maybe I should go see what's going on over there.
Like your body is instantly reacting because it is unconsciously picked up on that scream before it's even registered in your brain.
