Abstract

The experiments were performed on the sciatic nerve of Rana temporaria. A single rectangular electric impulse and a series of rectangular microsecond impulses were used for stimulation. The threshold amplitude of a single impulse and the average voltage in series of impulses were compared. It was experimentally shown that application of a series of impulses as a stimulus necessitated less values of stimulation near the threshold. There was no significant difference between the average voltage in a series of impulses and the amplitude of a single rectangular impulse in stimulation far up the threshold.

摘要

实验在林蛙的坐骨神经上进行。使用单个矩形电脉冲和一系列矩形微秒脉冲进行刺激。比较了单个脉冲的阈值幅度和一系列脉冲中的平均电压。实验表明,作为刺激施加一系列脉冲在阈值附近需要较小的刺激值。在远高于阈值的刺激中,一系列脉冲中的平均电压与单个矩形脉冲的幅度之间没有显著差异。
