The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system, Gershon says. This multitude of neurons in the enteric nervous system enables us to feel the inner world of our gut and its contents.
A hundred million neurotransmitters line the length of the gut, approximately the same number that is found in the brain.... If we add the nerve cells of the esophagus, stomach and large intestine, there are more nerve cells in the gut than there are in the entire remainder of the peripheral nervous system.he gut's brain, known as the enteric nervous system (ENS), is located in sheaths of tissue lining the esophagus, stomach, small intestine and colon. Considered a single entity, it is packed with neurons, neurotransmitters and proteins that zap messages between neurons or support cells like those found in the brain.
