and subcortical regions that were important for emotion, and memory, and learning, people who had better connections showed more of a bias because of two things.
the subcortical pathway we've been able to time all this very precisely in the rat brain and it takes in order for a sound to get to the
So these subcortical things in adolescence are more robust.
But these subcortical areas are just more active.
amydala from the subcortical pathway takes U about 10 or 12 milliseconds so it take a second divide into a thousand parts and after 12 of those little Parts
So if we look at those subcortical areas, like the amygdala and the thalamus-- so this is a slice through the brain right about here on the left,
So if we look at those subcortical areas, like the amygdala and the thalamus-- so this is a slice through the brain right about here
We've said that the subcortical regions, the body, the brain stem, and the limbic area, nature has made more active in an adolescent.
short is that we have these subcortical structures deep within our brain, evolutionarily ancient structures that become activated by
Freud called the unconscious mind that these are the subcortical memory systems the basil ganglia cerebellum amydala and
So the brain's threat detection mechanism is subcortical , unconscious, and the wiring for this is in the amygdala and in the hypothalamus.
And if you look at the volume of these two subcortical areas, the humans are displayed in gray and zombies are displayed in orange.

When it comes to these deeper subcortical structures, uh they they they don't function like that.
But one of the things they do is they regulate control of subcortical networks, networks that are buried deep in the brain.
But one of the things they do is they regulate control in subcortical networks, networks that are buried deep in the brain.
But if you remove the orbitofrontal cortex from the equation, what happens is these subcortical fight or flight responses are unchecked.
So this little alien-looking creature in here, that's a subcortical nuclei and part of the basal ganglia circuit.

So this little alien looking creature in here, that's a subcortical nuclei and part of the basal ganglia circuit.
we can think of of behavior that's dangerous but that doesn't register to our subcortical minds as dangerous because it's too abstract,
your financial decision is decision- making our financial decision- making is made at what's called a subcortical region below the Neo neocortex what we
And because those are all below this higher area, the cortex, it's called the subcortical source of emotion.
between our higher complex reasoning, the frontal cortex, and our primitive subcortical limbic system regions like the amygdala.
