Abstract
The effect of fluctuations of the transmembrane potential on the generation of the action potential has been studied using a computer model of a SAN cell. It was shown that the magnitude of the effect increases with increasing concentration of acetylcholine. The effect is well seen near and after the cessation of spontaneous oscillations. While applying and washing acetylcholine, a hysteresis loop has been observed.
摘要
利用窦房结细胞的计算机模型研究了跨膜电位波动对动作电位产生的影响。结果表明，该影响的幅度随乙酰胆碱浓度的增加而增大。在自发振荡停止时及之后能清楚地看到这种影响。在施加和冲洗乙酰胆碱时，观察到了一个滞后回线。
