One of the most mind-blowing things I learned about when studying psychology was the theory of distributed consciousness. Basically it goes along the lines that though most of our neural matter is in the head (i.e. brain) there are pockets of it here and there throughout the body. For instance in each of the sections of the spine - highly trained movements are coordinated between these. They are signalled by the brain but motor control can happen largely independently.
One thing that stood out is that the highest concentration of this neural matter is in the stomach. Your stomach does have access to some information about the outside world: Bass sounds, orientation, and proprioceptive activities. But it is largely ignorant of the outside world because it doesn't have access to the main senses the way the brain does. This sits nicely with the "gut feel" lore, where your stomach is uneasy about something though your brain says things should be fine. Your stomach can't be fooled by your senses.
