And then my palm is the brainstem.
And this is the part of our brain that is controlling our breathing, our heart rate, all of those things you don't want to have to think about to stay alive, right?
My thumb represents the limbic system.
So this is the emotional part of our brain.
The amygdala lives here, which is that emotion, kind of like smoke alarm center.
Also the hippocampus, which is our memories.
And together, the limbic system and the brainstem, that's our survival response, right?
My fingers over top represent the cortex, which is all the squiggly stuff that you imagine when you picture a brain, right?
And that is the part of our brain that allows us to think, to plan, to follow through with those plans, to be creative.
And my front knuckles are the prefrontal cortex right here, which is where all that executive functioning and smart human stuff happens.
And the cortex is so important, but it's super slow compared to the lower parts of our brain, those subcortical parts.
And I'm telling you all of this right now.
It seems like it doesn't relate, but it does.
Because when we experience stress and trauma... So before I experience something scary or stressful, we're going along.
All the parts of our brain are together.
They're functioning.
They're talking to each other.
If I'm startled, say I hear a loud noise...
your lid flips, your cortex goes offline so that these lower parts of the brain can be really, really quick and help me decide, is that a threat?
Is it just a random noise?
