No, there are many brain changes involved with PTSD including the prefrontal cortex and the study clearly didn’t take it into account.

I didn’t even say anything about the amygdala. I said PTSD. Don’t put words in my mouth.
Maybe you should have explicitly stated your point?
And I don’t see anything in your link about subsequent changes to size or activity of the prefrontal cortex due to PTSD.
Although I admittedly just skimmed it.
So if that links backs up your argument (whatever that was) please link the relevant part.
