Electroacupuncture at P5-P6 modulates gastric distension-induced sympathoexcitatory responses. A: consistent evoked responses with repeated gastric distension every 10 min. B: displays reduced reflex during and after stimulation of P5-P6 acupoints overlying the median nerve. Line underneath bar histogram represents 30 min of EA. ΔMAP, change of mean arterial blood pressure. *Significant difference, P < 0.05, compared with control before EA. #Significant difference, P < 0.05, compared with control group. In this and other figures, mean ± SE below each bar represents baseline MAP before gastric distension.
