By using both optical and mechano-electric detectors, we have shown that the squid giant axon swells when an action potential is generated. The maximum swelling is reached at the peak of the action potential. The undershoot of the membrane potential is associated with a marked shrinkage of the axon. We have also demonstrated these mechanical changes in axons from which a major portion of the axoplasm has been removed. We have examined the effects of changing the tonicity of the external medium and of applying several chemical reagents.
通过使用光学和机电探测器，我们已经表明，当产生动作电位时，鱿鱼巨轴突会肿胀。在动作电位的峰值时达到最大肿胀。膜电位的负后电位与轴突的明显收缩有关。我们还在已去除大部分轴浆的轴突中证明了这些机械变化。我们研究了改变外部介质的张力以及应用几种化学试剂的效果。
