Propagative characteristics of conscious mouse distal colonic contractions. A miniature pressure transducer catheters were placed in the distal colon of mice (2 and 4 cm proximal to the anus) under brief isoflurane anesthesia. A: number of propagated and nonpropagated contractions. B: correlation between the amplitude of contractions and their chance to be propagated. C: mean amplitude of propagated vs. nonpropagated contractions; n = 8 mice. *P < 0.05 vs. nonpropagated contractions.
