2. Methods:We used ethanol at different concentrations for the sciatic nerve stem of the unorganized hoptoad and measures its absolute refractory period.

方法:本实验对离体蟾蜍坐骨神经干进行不同浓度乙醇处理,测其绝对不应期。

3. Methods: By recording the action potential of sciatic trunk and contract curve of sural muscle of hoptoad, and checking the time of fatigue in nerve center, neuro-muscular junction and muscle.

方法:记录蟾蜍坐骨神经干动作电位和腓肠肌收缩曲线,测定低位运动中枢、神经-肌接头和骨骼肌出现疲劳的时间并加以比较。
