Abstract

The membrane potential of the E2 axon and the bender muscle fibers increased with temperature. The input resistance of the axon, the spike amplitude and time course declined with temperature. Excitatory junctional potentials (ejps) exhibited maximum amplitudes and minimum facilitation at about the same temperature. Ejp time course and muscle membrane input resistance declined with temperature. Tension produced by the muscle also declined but then increased when additional spikes were generated in the periphery of the E2 axon.

摘要

E2轴突和弯曲肌纤维的膜电位随温度升高而增加。轴突的输入电阻、动作电位幅度和时程随温度下降。兴奋性突触后电位（ejps）在大约相同温度下表现出最大幅度和最小易化作用。Ejp时程和肌膜输入电阻随温度下降。肌肉产生的张力也下降，但当在E2轴突外周产生额外动作电位时张力又会增加。
