✦ Synopsis

An atraumatic balloon technique is presented whereby gastric motor function is directly recorded from conscious, unrestrained rats continuously for as many as 5 days and intermittently for periods up to 2 weeks. Intragastric motility patterns resulting from these animals demonstrate good recording stability and are remarkably free of artifacts during their physiological and behavioral activities. The tracings during fasting most frequently showed periods of relative quiescence with occasional bursts of high amplitude contractions. After stimulation with either food or water, digestive contractions were obtained. The inherent limitation to the usefulness of this technique is anatomical inasmuch as it is less applicable for use in very small animals.
