本文研究了单个朗氏结对短时间双相刺激电流的反应。已知这样的刺激模式比较长的双相刺激更不可能诱导组织损伤。阳极相的脉冲对的存在下，被发现废除的情况下，单独的阴极相附近的阈值的激发。此外，来自猫的胫骨前肌的峰值抽动力被发现通过使用双相运动神经刺激代替单相刺激而降低。通过在双相刺激波形的相位之间引入100 μs的延迟，可以消除现象。
The response of a single Node of Ranvier to short duration biphasic stimulating currents was studied. Such stimulus patterns are known to be less likely to induce tissue damage than are longer monophasic stimuli. The presence of the anodic phase of a pulse pair was found to abolish excitation in cases where the cathodic phase alone was near threshold. In addition, peak twitch force from the tibialis anterior muscle of cat was found to be reduced by the use of biphasic motor nerve stimulation in place of monophasic stimulation. The abolition phenomenon could be eliminated by the introduction of a delay of 100 μs between the phases of a biphasic stimulus waveform.
