Fig. 8: 3D-TIP of intestine in anesthetized mice.

a 3D-TIP images of three human hairs located at depths of −2, 1, and 5 mm. Scale bar: 1 mm. b From left to right: The depth index map of two sections of an intestine; the intestine image at the 0 mm depth; the MAP image of intestines projected along the axial direction. c The 3D image of two sections of intestine. d, e The spatial-temporal maps along the lateral and the axial plane of the intestine labeled within the blue box in (b), respectively. f, g The spatial-temporal maps along the lateral and the axial plane of the intestine labeled within the red box in (b), respectively. h Intestine images of one mouse (green line shows the selected intestine) over different depths. i The spatiotemporal map of the labeled intestine in (h). The segmentation motor pattern can be clearly seen. Scale bars in (b) and (h): 5 mm.
