Slow junctional potentials elicited by electrical field stimulation (EFS) in proximal and distal colonic muscles from control and dextran sodium sulfate (DSS)-colitis mice. (A, B) Raw traces of EFS-elicited slow inhibitory junctional potentials (sIJPs) in the colonic muscles of control and DSS-colitis mice (3, 6, and 9 Hz for 5 seconds; black bars in each panel). (C, D) Summary of the data showing the average amplitude of sIJPs in the proximal and distal colonic muscles of control and DSS-colitis mice (in the proximal colon, n = 7/group, *P < 0.05; in the distal colon, n = 7/group, *P < 0.05).
