Methods: By recording the action potential of sciatic trunk and contract curve of sural muscle of hoptoad, and measuring the time of fatigue in nerve centre, 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、骨骼肌出现疲劳的时间并加以比较。

Their main finding was that a nerve impulse, now known as an action potential, is caused by the movement in opposite directions across the axon's surface membrane of sodium and potassium ions.
