I don't mean to quibble with something I know so little about, but with something as advanced as the human brain that's all I can do: I think this is less a matter of the prefrontal cortex, we're all controlled by our amygdala. Our lizard brains kick in big time in times of stress and disaster.

To us laymen, maybe a debate between the amygdala and the frontal cortex amounts to a bar discussion of who was the better PM, Pitt the Younger or Pitt the Elder. Heavy stuff anyway.
