Antenna model for passive myelinated nerve fiber

Abstract

A myelinated nerve fiber, stimulated by a current generator at the fiber beginning, is modeled as a straight thin wire antenna. The model is based on the corresponding Pocklington integro-differential equation for the perfectly conducting wire in a lossy unbounded homogenous space. Pocklington integro-differential equation in the frequency domain is numerically solved by means of the Galerkin Bubnov Indirect Boundary Element Method (GB-IBEM). By solving the Pocklington integro-differential equation, intracellular current distribution along the myelinated nerve fiber in the passive state is obtained.
