Dynamics of excitation pulses in two coupled nerve fibers

Abstract

In this paper, we study the phenomena of interaction of traveling pulses in a system of two coupled nerve fibers. Each fiber is modeled by a discrete chain of mutually coupled Fitz Hugh-Nagumo excitable elements. The interaction among the fibers can be distributed, homogeneous, and also localized at certain points in space. In the case of homogeneous interaction, we show the possibility of interfiber synchronization of pulses. For localized interactions, we study the dynamics of point and two-point contacts, allowing us to perform effective control over the propagation of excitation along the coupled fibers.
