  • Title: Regional differences in fiber size in the cochlear nerve.
    Author: Romand R, Romand MR, Marty R.
    Journal: J Comp Neurol; 1981 May 01; 198(1):1-5. PubMed ID: 7229135.
    Abstract:
    The topographical variations in fiber size in the cochlear nerve of cat were quantitatively studied by electron microscopy. Measurements of fiber size as they appeared at the outlet of the spiral lamina show that fibers originating from the basal part of the cochlea are larger than those from the apex. When the diameter of apical fibers and their axoplasms at two different levels are compared, a significant variation in size is observed. As they appear in the internal acoustic meatus the apical fibers are larger at the level of the nerve trunk compared with the same fibers near the ganglion cell bodies. There are significant differences in fiber diameter with regard to their length for fibers derived from the apical turn. These results are compared with previous findings.
