The effect of different intensities of EA at LI11 on jejunal motility in WT, β₁β₂ ^−/− and M₂M₃ ^−/− mice. a-c Representative tracings of jejunal motility with different intensities of EA in WT, β₁β₂ ^−/− and M₂M₃ ^−/− mice, respectively. d-f The fitting curves of the EA effect with different intensities on jejunal motility in WT, β₁β₂ ^−/− and M₂M₃ ^−/− mice, respectively, showing the relationships between different intensities of EA (1, 2, 4, 6, and 8 mA) and the rate of change rate in jejunal pressure. g The integrate fitting curve showed the enhanced effect of EA with different intensities on jejunal motility in three groups. Data are expressed as mean ± SEM (n = 8 mice). ^* P < 0.05 vs WT mice, ^# P < 0.05 vs β₁β₂ ^-/− mice, independent t-test. WT, wild-type
