You have more neurons in your stomach and intestines than in your spinal cord or peripheral nervous system. Some call it “the second brain:”

Technically known as the enteric nervous system, the second brain consists of sheaths of neurons embedded in the walls of the long tube of our gut, or alimentary canal, which measures about nine meters end to end from the esophagus to the anus. The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system…

And yes, apparently there is a new field of medicine known as Neurogastroenterology!
