this is the area that new neurons are being generated on an as needed/ad hoc basis.
this is where discrimination is extremely important.
friend or foe? Familiar or unfamiliar?

The amygdala is right there. I think it even comes into it.
So it is the guard house.
it is the triage nurse: The prioritizer.
it won’t know all the details but it’ll know just enough.
OK. I think this is in the right direction.
but I may be wrong or oversimplifying or have things flipped.
I suspect I may need to distinguish between encoding and retrieval.
