Trauma can cause changes in your brain, this includes cPTSD comming from long term constant stress and abuse where each situation by itself might not be traumatizing but the commulation is.

and systematic discriminatory can be quite traumatizing

all experiences can cause long term changes in your brain

Surely that's a fundamental by-product of experience?

Otherwise, you wouldn't have the ability to recall that experience. ^-^

there is a difference between neuron wiring/conditioning/learning and the changes I was referring, too

you could say on is changes to the parameters of your brain

and the other are more fundamental changes

like trauma can cause brain damage which can show up on scans in similar form to physical caused brain damage....

yes, but it's not just neuron wiring (i.e. conditioning) but more fundamental effect, including outright brain damage

They allege something of the sort in the discussion, but the paper itself only reports an association. It is rather straightforward to imagine potential causality hypotheses ranging from what you've just said to something so politically incorrect nobody would dare publish it.
