According to Dr. Gershon, author of The Second Brain, you feel like there are butterflies in your stomach when brain neurons send a message of anxiety to gut neurons. The gut neurons then send messages back up to the brain. However, it has been discovered that gut neurons can work on their own, initiating messages that go up to brain neurons when the GI system isn’t happy. When are the gut neurons unhappy? When you overeat or eat food that irritates the GI system. When you are stressed emotionally, frightened or overly anxious, or have constipation or diarrhea, etc. (Irritable Bowel Syndrome or IBS is not the same as IBD or inflammatory bowel disease.)

right amount of Serotonin. Too little and your mood may fall; too much and you run the risk of being overly anxious. In the GI System, serotonin impacts digestion, bowel movements, and appetite. It can help you realize that you are full, and that eating more food would be over-eating.

The gut-brain-axis is a term that refers to the back-and-forth communication system between the brain and the gastrointestinal or GI system. Or, as some might say, the talk that goes on between neurons in the human brain and those in the second brain in the gut. This communication occurs primarily via the vagus nerve. Studies have shown that the gut-brain-axis is becoming increasingly important as a therapeutic target for gastrointestinal and psychiatric disorders. It is thought to play an important role in the relationship between the gut, the brain, and inflammation, especially in disorders such as inflammatory bowel disease (IBD), depression, and posttraumatic stress disorder (PTSD).

It refers to the neurons that live in the walls of your Enteric Nervous System or ENS. That’s another term for your Gastrointestinal (GI) Tract or gut. Its two-layered walls stretch from your esophagus to your rectum. Consensus used to be that neurons were relegated to the brain and spinal cord. Then researchers discovered ‘neurons’ in the ENS or GI system, counting perhaps a million or more. As equipment became more sophisticated, estimates were revised upwards to maybe 200-600 million. Recently I heard someone say that there may be as many neurons in your gut as in parts of your brain.
