<unk> , also known as<unk>  myoelectric<unk> , migratory<unk><unk> , migratory myoelectric<unk>  and<unk> , is a pattern of electrical activity observed in the gastrointestinal tract in a regular cycle during fasting.<unk>  was discovered and characterized in fasting dogs in 1969 by Dr. Joseph H. Szurszewski at the Mayo Clinic. He also showed that this activity stops upon eating a meal, and suggested that it induces a<unk>  activity that acts as a "interdigestive housekeeper" in the small intestine. These<unk><unk> es trigger peristaltic waves, which facilitate transportation of indigestible substances such as bone, fiber, and foreign bodies from the stomach, through the small intestine, past the ileocecal sphincter, and into the colon.<unk>  activity varies widely across individuals and within an individual when measured on different days. The<unk>  occurs every 90–230 minutes during the interdigestive phase (i.e., between meals) and is responsible for the rumbling experienced when hungry. It also serves to transport bacteria from the small intestine to the large intestine and to inhibit the migration of colonic bacteria into the terminal ileum; an impairment to the<unk>  typically results in small intestinal bacterial overgrowth.
