Fig. 2: Quantification of uterine peristalsis waves.

A Uterine isochrone maps from the same uterine peristalsis wave as in Fig. 1I. Warm and cool colors represent early and late activation, respectively. The white arrow depicts the peristalsis wave propagation direction. B Uterine magnitude map from the same uterine peristalsis wave in Fig. 1I, showing the magnitude distribution over the entire 3D uterine surface in one peristalsis wave. C Distribution of uterine peristalsis directions (C–F, F–C, others) and initiation (D) and termination (E) sites (cervix, fundus, and other areas) analyzed from the entire electrical recording. Initiation (F) and termination (G) site distribution probability maps of C–F and F–C uterine peristalses for the entire imaging session (see details in Materials and Methods).
