The distribution of a tracer, lanthanum, in the brain was examined in the electron microscope both after implantation and after immersion of fixed small blocks. In both cases, the distribution was essentially the same. It was found in the extracellular spaces, between myelin lamellae, between the transverse bands at the nodes of Ranvier, and within the periaxonal space. It was concluded that the transverse bands consist of several, separate, parallel bands which, with their intervening spaces, trace a continuous helical path from the extracellular spaces at the nodes of Ranvier to the periaxonal spaces.
