[Kinetics of sodium current inactivation in Ranvier's node membrane].
The possibility to describe the inactivation kinetics of sodium current in the Ranvier node membrane in terms of models with independent processes of activation and inactivation, was experimentally tested. Dependence of kinetic characteristics on the potential suggested the existence of three types of nerve fibers with different models of inactivation system. The models with independent systems of activation and inactivation were concluded to be not quite adequate.
