Abstract

It was shown that during rhythmic stimulation of the node of Ranvier in the potassium-free solution there was an exponential decline of the trace hyperpolarization. This is attributed to the fact that potassium ions released from the fiber during the activity collect in the premembranous space separated from the external solution by diffuse barrier.

摘要

结果表明，在无钾溶液中对郎飞结进行节律性刺激时，微量超极化呈指数下降。这归因于在活动期间从纤维释放的钾离子聚集在由扩散屏障与外部溶液隔开的膜前空间中。
