Example electrode traces from the laparoscopic and reference electrodes. (A) Positioning of a reference electrode (128 electrodes in total; 360 mm2) and the laparoscopic device (32 electrodes in total; 707 mm2) on the stomach during data collection. (B) The electrograms for five recording channels from the laparoscopic device, and six from the reference array are displayed along with their locations on the electrode arrays. The electrograms demonstrate consistent aboral slow wave activity, with six events occurring within the displayed period of 90 seconds for both the laparoscopic device and reference electrode (frequency: 2.6 ± 0.3 cpm vs 2.5 ± 0.5 cpm).
