Computational model design. A two-part computational model has been developed. The first part of the model calculates the electrical field generated by the two electrodes: a pin electrode (A) or a patch electrode (B). The skin model consists of four rectangular skin layers (C). The second part of the model consists of two axon models (Aδ and Aβ) with the spatial location in the skin model illustrated in (C). The morphology of the myelinated axon sections consists of three parts: node of Ranvier, juxtaparanode, and internode (D). The figures are not drawn to scale. To see this figure in color, go online.
