Fig. 1From: Alteration of neuromuscular transmissions in the hamster colon following the resolution of TNBS-induced colitisMechanical responses elicited by electrical field stimulation (EFS) in an isolated segment of the hamster colon. Representative tracings of EFS-mediated contraction and relaxation in the hamster colon are shown. Electrical stimulation was applied using multi-pulses of 20 V each, with 0.3-ms pulse duration at 2 Hz (a) or 20 Hz (b) for 1 s; longitudinal mechanical responses were recorded isometrically.
