    Techniques Used: Control

    Assessment of rat model. ( a ) Different EMG waveforms changes response to gastric distension (GD) of 20, 40, 60 and 80 mmHg in control rats and IA-treated rats. ( b ) Gastric emptying results in control rats and IA-treated rats. The index was detected from 12 sacrificed rats after the 9th week (6 rats were randomly picked in control group and IA-treated group, respectively). The independent sample t-test was used. ( c ) EMG change ratio response to GD in all rats when rat model was induced. ( d ) The open field test (OFT) results when rat model was induced in all rats. All indexes were tested after the 9th week and before aVNS or sham-aVNS. One-way ANOVA was used, and the LSD method was used for post hoc tests in EMG change ratio and OFT. EMG: electromyography. * p < 0.05, ** p < 0.01, **** p < 0.0001. C: control group; IA: IA-treated group. n = 6 per group. Data were presented as means ± standard deviation.
