Ultrastructure and Conduction Properties of Visual Callosal Axons of the Rabbit
The corpus callosum of most mammals is comprised of both myelinated and nonmyelinated axons, most of which are less then 1 μm in diameter (Fleischhauer and Wartenberg, 1967; Seggie and Berry, 1972; Tomasch, 1954; Tomasch and MacMillan, 1957; Waxman and Swadlow, 1976a). Characteristics of impulse conduction along such axons in the central nervous system are relatively unstudied. In the present chapter we review our work on the ultrastructure and conduction properties of visual callosal axons of the rabbit and also present preliminary data on the conduction properties of callosal axons of the macaque monkey.
