Fig. 3From: Intraoperative serosal extracellular mapping of the human distal colon: a feasibility studyPeriodic bioelectrical activity recorded from adjacent consecutive electrodes on the distal human colon. A 8 cpm activity. B 4.5 cpm activity. These were not considered propagating slow waves per pre-specified criteria, i.e. the simultaneous registration across multiple channels (no lag), morphology, and lack of slow wave repolarisation [29, 30]Back to article page
