[Dependence of the nerve pulse generation threshold on the ability of forming an input signal based on the Hodgkin-Huxley model].

Different methods of definition of the threshold of the action potential (AP) generation were considered. It was established that the threshold defined as a difference between the critical value of the membrane depolarization and the resting potential was practically independent of the value and duration of an input signal which was given as a stepped function. It was shown that the critical values of the membrane depolarization could be defined by the point of bend, as well as by the point of maximum of the curve curvature on the frontal part of AP.
