abstract：:As oligodendrocytes wrap axons of the central nervous system (CNS) with insulating myelin sheaths, sodium channels that are initially continuously distributed along axons become segregated into regularly spaced gaps in the myelin called nodes of Ranvier. It is not known whether the regular spacing of nodes results fro...
