Abstract

Axonal growth has been studied in the ependyma of the developing trout tail. Results of the ultrastructural investigation show that intercellular spaces or channels develop in advance of the growth of the pioneering neurites. This developmental process is reminiscent of the axonal patterning described in the growing ependyma of the newt. It gives some additional support to the β€œblueprint hypothesis” as presented by some of us (Singer et al., '79), which assign to the glial cells β€œthe pattern of the primary neuronal pathways”.
