Isolated large rat nerve fibres with diphtheria toxin induced paranodal demyelination were investigated. These fibres had increased membrane time constant of the demyelinated nodal segment, related to a large increase in capacitance (5 to 50 times). The resting conductance was less increased (2 to 3 times), meaning that the internodal axolemma has considerably higher resting resistance than the nodal membrane. A large variation in action potential amplitude was found which was unrelated to the size of the nodal widening and the passive electrical properties.
对用白喉毒素诱导结旁脱髓鞘的大鼠分离大神经纤维进行了研究。这些纤维脱髓鞘结段的膜时间常数增加，这与电容大幅增加（5至50倍）有关。静息电导增加较少（2至3倍），这意味着结间轴膜的静息电阻比结膜高得多。发现动作电位幅度有很大变化，这与结增宽的大小和被动电学特性无关。
