Abstract This study was undertaken to investigate thecorrelation between power dynamics of gastric electricalactivity (GEA) assessed with different recordingtechniques. A total of seven eight-channel 1-hr combined recordings were obtained from three subjects infive consecutive postoperative days. Four channels wererecorded from bipolar electrodes implanted into thegastric antral wall, and four channels wereelectrogastrographic (EGG). Six pairs of bipolar electrodes wereinserted into the antral wall (three anterior; threeposterior) of 16 anaesthetized dogs. Fourteen-channel(six internal GEA and eight EGG) 1/2-hr recordings were obtained from each dog. Sets of powervalues calculated from channel pairs (internal, EGG ormixed) were cross-correlated and the significance of theobtained correlation coefficients was examined (P 〈 0.05). The majority of powercorrelations of internal GEA channel pairs, and those ofmixed (internal GEA-EGG) channel pairs wereinsignificant. These findings question the claims thatEGG power dynamics mirrors the power dynamics of internalGEA.
