Nerve Impulse Propagation in a Branching Nerve System: A Simple Model

摘要

Local spatial changes of nerve axon geometry such as diameter increase and branching, may cause that action potential waves approaching a region of geometric change fail to propagate beyond it. This effect was examined for a special kind of nonuniformity within the framework of a simple model: an initial value problem for a single nonlinear diffusion equation on an unbounded domain.
