On a minor pedantic note, its more like the amygdala keeps the score. There is no difference between physical abuse and emotional abuse when it comes to the final end result on the brain.
That's .. the unsolved research question under discussion? As to whether there is a score at all, where it is kept, and how it might be affected? And while is seems there is some evidence, we're still in the middle of the replication crisis?
According to Dr. Sapolsky (Why Zebras Don't Get Ulcers, Behave), there's ample evidence of enlarged, hyperactive amygdalas in chronically stressed individuals, both on artificially stressed lab rats and when looking at differences in individual human beings.
