What's All The Fuss About Your Gut?
A Johns Hopkins expert referred to the gut as a second brain hidden within the walls of the digestive system. The gastrointestinal tract is lined with over 100 million nerve cells, and scientists have given it the name “the enteric nervous system”. These nerves, neurons and neurotransmitters found in the gut and brain communicate back and forth. An example of the brain and emotions affecting the gut is irritable bowel syndrome, characterized by hyperactivity of the nerves in the enteric nervous system that can be triggered by emotional shifts.
