1.电刺激紫贻贝鳃神经可诱发鳃侧细胞的动作电位，随后产生纤毛阻滞反应。2. 2.当鳃丝灌流无钙培养基时，动作电位变形，停止反应消失。随后，动作电位减小至小的去极化。3. 3.重复刺激神经或应用5-羟色胺增加了纤毛的跳动频率，膜电位变化不大。4. 4.可以得出结论，侧细胞膜的再生去极化活动是负责纤毛逮捕，但不是为控制的纤毛节拍频率。
1. Electrical stimulation of the branchial nerve in Mytilus edulis elicits an action potential followed by a ciliary arrest response in the lateral cells of the gill. 2. 2. The action potential was deformed and the arrest response was lost when the gill filament was perfused with a Ca-free medium. This was followed by a diminution of the action potential to a small depolarization. 3. 3. Repetitive stimulation of the nerve or application of 5-hydroxytryptamine increased the beat frequency of the cilia with little change in the membrane potential. 4. 4. It is concluded that a regenerative depolarizing activity of the lateral cell membrane is responsible for the ciliary arrest but not for the control of the ciliary beat frequency.
