Fig. 2: 2D-TIP imaging of intestinal motility in free-moving and anesthetized mice.
From: Trans-illumination intestine projection imaging of intestinal motility in mice

a Temporal intestinal images of a free-moving mouse. b Spatial-temporal maps of the intestinal region labeled with green arrows in (a), (Supplementary Videos 1, 2, and 3). c Intestinal images of an anesthetized mouse (green arrow shows the intestinal region of interest). d Spatial-temporal map of the interested intestine in (c) (Supplementary Video 4). Scale bar: 10 mm. e The average intensity of the intestinal cross-sectional profile shows segmentation frequencies of free-moving and anesthetized mice. f Frequency analysis reveals that the intestinal segmentation in free-moving mice occurred at a faster rate than that of the anesthetized mice (mean ± s.d., n = 5 mice, two-sided Wilcoxon rank-sum test).
