Visceral behavior refers to the motility of the gastrointestinal tract, whose movements can actually be “observed” by the sounds that it makes. The wonderful onomatopoetic word for these intestinal rumblings and gurglings is borborygmus (plural: borborygmi). An entire system of body-therapy is based upon listening to a spectrum of these gut sounds with an electronic (fetal) stethoscope while different parts of the body are touched and gently manipulated.94
