Butterflies In My Stomach: The Gut-Brain Connection
Any time that you have to make a “gut wrenching decision” that causes actual, physical discomfort, or you have “butterflies in your stomach” when you are nervous, your brain and your gut are interacting. Your brain is sending signals to your Enteric Nervous System (ENS), the tens of millions of nerve cells that line the interior walls of your entire digestive tract, to cause these sensations. Some scientists are now suggesting that it might often be the other way around – that our bodies pick up on cues from our environment, and our ENS reacts so as to send warning signals to the brain.
