The vagus nerve facilitates bidirectional information flow between the brain and bodily organs.

“We have a system in our body that connects our brain to all of our bodily organs and connects all of those bodily organs to our brain. And that communication between brain and body in both directions creates a situation where either we are positioned to do things well or we are positioned to do things poorly. So I really want to dive in and dissect what is this system of brain body communication. What does it look like? What are the actual neurons and connections? The system that's most often associated with this is our 10th cranial nerve called the vagus nerve.”
