本文以螯虾细小神经轴突为标本，采用双玻璃微电极细胞内刺激与记录技术，观察了几种钠、钾离子通道药物对神经膜静息电位、阈电位、静息电位与阈电位之间差值、标准电量ａ及常数ｂ的影响。结果表明：静息电位和静息电位与阈电位之间差值与常数ｂ变化方向一致；而与标准电量ａ变化方向不尽相同。提示：静息电位和静息电位与阈电位之间差值主要反映神经膜应激性。
In this paper, the ciliary shrimp small axon as a specimen, the use of double glass microelectrode intracellular stimulation and recording technology, observed several sodium, potassium channel drugs on the nerve membrane resting potential, threshold potential, resting potential and threshold potential The difference between the standard charge a and constant b. The results show that the difference between resting potential, resting potential and threshold potential is in the same direction as the constant b, but not in the same direction as the standard charge. Tip: resting potential and resting potential and the difference between the threshold potential mainly reflects the neural membrane stress.
