Myelinated axonal model used to simulate the modulation of axonal excitability by high-frequency biphasic (HFB) electrical stimulation. The inter-node length Δx = 100d; d is the axon internal myelin diameter. L is the nodal length. Each node is modeled by a resistance-capacitance circuit based on SRB model. Ra: inter-nodal axoplasm resistance; Rm : nodal membrane resistance; Cm : nodal membrane capacitance; Vi,j : intracellular potential at the jth node; Ve,j: extracellular potential at the jth node.
