概要
- 論文の詳細を見る
The sucrose-gap method was adapted to record the action potentials of bullfrog cardiac muscles. The size and configuration of action potentials recorded from atrial or ventricular strips with the sucrose-gap method were similar to those recorded with intracellular microelectrodes. Action potentials could be maintained at a constant amplitude and time-course for up to 3 hours. Furthermore, during recording of action potentials, it was possible to apply DC current to hyperpolarize or depolarize the muscle membrane. Thus the present method in combination with the intracellular microelectrode method will provide valuable information concerning the physiology of cardiac muscle fibers.
