  • The following parameters are unchanged from the single-compartment bEIF model (Table 3): membrane capacitance density Cm, leak reversal potential EL, slope factor of the spike-generating current KT, ceiling factor of the spike-generating current at, starting voltage of repolarization current Vrep, time constant of repolarizing conductance τrep, amplitude factor of repolarizing conductance Arep. The axial resistivity Rax is unchanged from the myelinated axon model (Table 4).
