What is trauma exactly? Or the ever-elusive concept known as the “flow state”? And why do some people just flat-out creep us out? It can all be explained by the autonomic nervous system — our body’s autopilot that keeps our heart beating, our lungs breathing, and our gut digesting; without us even thinking about it. The Polyvagal Theory is a new understanding of how our nervous system works, and explains everything from trauma, to the very essence of social behavior; while shedding light on possible treatments for autism and trauma. You’ll never think of your body and brain the same way again.
