  1. As far as I know , biological brains don't use back propagation. But there are neural circuits where the flow of information goes opposite. There is also the chemical side of things integrating many levels of homeostasis from hunger to pain to emotion. I would say the combination of those two are the mysterious correlates of back propagation, back propagation being the obviously oversimplified version.
