Polyvagal Theory, originally developed by Stephen Porges, PhD and widely taught by Deb Dana, LCSW, offers a neurophysiological framework to consider the reasons why people act in the ways they do. Through a Polyvagal lens, we understand that actions are automatic and adaptive, generated by the autonomic nervous system well below the level of conscious awareness. This is not the brain making a cognitive choice; these are autonomic energies moving in patterns of protection. And with this new awareness, the door opens to compassion (from Deb Dana and The Rhythm of Regulation).
