实验在14只猫身上进行。实验前于无菌条件下在腹膜后一侧(常为左侧)内脏大神经中枢端埋藏电极。术后三天,动物恢复自由活动后在隔音室内开始实验。 刺激一侧内脏大神经中枢端(强度为6～45伏,波宽为1.0毫秒),能引起双前肢足垫皮肤电位变化,多为双相快反应型,波幅在同一动物同一次实验中比较恒定。634例次统计的皮肤电位幅度为1302.64±36.729微伏(均值±标准误),以刺激侧 Experiments were performed on 14 cats. Before the experiment under sterile conditions in the retroperitoneal side (often left) buried visceral nerve center electrode. Three days after surgery, the animals started their experiment in a soundproofed room after resuming free activity. Stimulation of the lateral visceral nerve center (intensity of 6 ~ 45 volts, wave width of 1.0 milliseconds), can cause double forelimb foot pad skin potential changes, mostly biphasic fast response, the same amplitude in the same animal experiments Constant. 634 sub-statistics of the skin potential amplitude of 1302.64 ± 36.729 microvolts (mean ± standard error) to stimulate the side
