The application of statistical communication techniques to the analysis of intestinal motility records has made available certain information that has heretofore been obscure. This information is:
1. A measure of total activity expressed in square millimeters of Hg.
2. The frequency and amplitude of segmental activity.
3. A measure of the random variations in the amplitude of the "segmental" waves.
4. A measure of random activity and the range and relative amplitudes of the frequencies making up this component.
