Fig. 7: Summary plots showing the difference in wavelet coherence and the variation in time difference between junction potentials recorded during CMCs.

Plot a displays the difference in the median of the absolute value of WCOH during and before CMC propulsion, recorded between the proximal and distal colon. The distribution of the statistic is shown overall datasets displayed using a conventional boxplot; the solid dark line designates the median, the box edges the first and third quartiles, and the whiskers extending up to 1.5 times the interquartile range. Plot b shows the variation in time alignment between junction potentials recorded during CMCs, between the proximal and distal colon, over increasing electrode separations. As the distance between the electrodes increases, the degree of variability between the two recorded activities also increases. The time difference is estimated using the phase of the WCOH.
