A model of a myelinated nerve axon is developed on the basis of FitzHugh-Nagumo dynamics under the assumption that the nodes of Ranvier are of small but finite width. It is shown that a periodic excited state may not exist if the width of the nodes is too small and the leakage across the myelin shea

This paper develops and uses comparison principles to study the time evolution of solutions to problems of the form (formula; see text) Such a system models an infinite myelinated axon with discrete, excitable nodes spaced unit distant apart.

## Abstract In vitro models of myelinating central nervous system axons have mainly been of two types, organotypic or dissociated. In organotypic cultures, the tissue fragment is thick and usually requires sectioning (physically or optically) before visual examination. In dissociated cultures, tiss
## Abstract We show that the free streaming operator with diffusive __multiplying__ boundary conditions is the generator of a quasiβbounded semigroup. We also examine some spectral properties of such an operator.
