Abstract

The question of sensitivity of amplitude and frequency curves of the Hodgkin-Huxley system to variations of maximal values of sodium (gNa) and potassium (gK) conductances is considered. Changes in the sensitivity produced by simultaneous changes in gNa and gK values are examined. It has been shown that simultaneous increase of the values of gNa and gK is accompanied by decrease of the sensitivity and, therefore, by improvement of quality of nerve fiber functioning.

摘要

研究了霍奇金-赫胥黎系统的幅度和频率曲线对钠电导（gNa）和钾电导（gK）最大值变化的敏感性问题。研究了gNa和gK值同时变化所产生的敏感性变化。结果表明，gNa和gK值同时增加会伴随着敏感性降低，从而神经纤维功能质量得到改善。
