Abstract
The nerve fibers running inside the organ of Corti was studied in cats by scanning electron microscopy, with thick serial sections method.
The tunnel spiral bundles took variable courses on the floor of the Corti's tunnel apart from the so-far reported site, medial corner of the tunnel base against the stalks of the inner pillar cells.
In the hardly-patent tunnel of Corti and Nuel's space in kitten, tunnel radial fibers ran on the floor of tunnel, slighly above the tunnel basilar fibers.
The nerve endings were not observed on the outer hair cells in 93g kitten. Fine thread-like fibers were found around the hair cell instead.
