| Abstract | In 1952 Hodgkin and Huxley published an empirical set of equations describing changes in the neural membrane potential of the squid giant axon during the application of depolarising or hyperpolarising stimuli. Since these equations were derived for an unmyelinated nerve fibre, reservations exist about their applicability to describe action potential propagation in myelinated mammalian nerve fibres adequately. Huxley (1959) suggested that by accelerating the activation and inactivation of membrane sodium ion permeability of the HH model fourfold, firing behaviour at a myeli-nated amphibian Ranvier node can be represented. The HH model is able to predict human ANF excitation, provided the nodal ion channel kinetics are accelerated tenfold (Rattay, 1990; Rattay and Aberham, 1993). This modified HH model shows improved human ANF response predictions by replacement of the squid morphometric properties by human morphometric properties, as well as changing the cable morphometric properties to those of human (Rattay et al., 2001b). The main endeavour of this study was to determine whether the HH model for un-myelinated nerve fibres could be modified more comprehensively to predict excitability |
