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.
Answers: Don't confuse axons with neurons. There are approximately 100,000,000,000 neurons in the human brain. Most of them are support cells and have nutritive, immunologic and protective functions. The number of axons per cell vary, mostly in the types of cells. For example Purkinje cells have many axons and therefore many more connections.
