Today’s topic is an interesting one that comes up a lot in the yoga world. In this episode, hosts Tiffany and Katja talk about the latest research and newest findings on the Polyvagal Theory. They discuss the evolutionary biology that Polyvagal Theory is based around, the neuroanatomy that’s involved, and assumptions that have been made about this complex aspect of the body.

Listen in to learn about the anatomy of the vagus nerve and how Polyvagal Theory is applied in yoga and therapeutic settings.

“The dorsal vagus is intervening more in the gut; the ventral vagus is engaging more with that social connection.” – Tiffany Cruikshank
