From: Breakdown of accommodation in nerve: a possible role for persistent sodium current
Equivalent circuit for a space-clamped motor neuron. The model consisted of a node and an internode. Both the node and the internode contained non-linear current sources, which were calculated from equilibrium potentials and conductances. Channel types and maximum ionic conductances: node, transient sodium (Nat, 276nS), persistent sodium (Nap, 7.1nS), fast potassium (Kf, 4.1nS), and slow potassium (Ks, 17.4nS); internode, slow potassium (Ks, 87.1nS) and leak conductance (L, 1.7nS). The linear parameters of the model were: Cn, nodal capacity (0.22pF), Ci, internodal capacity (379pF), Cm, capacity of the myelin sheath (0.17pF), and Ril, internodal leak resistance (41 MΩ).
