Polyvagal Theory

Polyvagal Theory doesn’t exactly fit into brain networks…but it does.  I’d like for you to stretch the network concept to include any system with a bunch of interacting nodes.  Polyvagal Theory explains the role of the vagus nerve (cranial nerve 10) in your social cognition.  In a nutshell, the vagal nerve has a dorsaland ventral branch. The dorsal branch is associated with lower vertebrate fight, flight, freeze behavior.  The ventral branch is associated with tend and befriend type responses to stress and allows continued use of facial micro-expressions and empathy.
