A silver method for staining normal axis cylinders of central nervous system structures

Abstract

The fink-Heimer stain for degenerating axons has been modified for demonstration of normal axis cylinders. The technique stains tissue prepared from a variety of fixation protocols. Vibratome prepared sections, coupled with an efficient use of laboratory time makes this procedure a simple, quick, and repeatable general technique. This preparation provides valuable insight into the histological organization of the intact central nervous system.
