Now over the past, I don't know, dozen years it and with great force over the last five years now, the main highway that is communicating the state of the body with the brain, it has been uncovered as being what we now refer to as the gut brain axis. And the highway is a specific bundle of nerves which emerged from the Vagal ganglia, the nodus ganglia. And so it's the vagus nerve that is innervating the majority of the organs in your body.
