The cochlear, especially the imprints in the under surface of the tectorial membrane, was studied with the scanning electron microscope in normal rabbits and guinea pigs. The imprints corresponding to the outer hair cells were seen in normal animals, but those of the inner hair cells were not found in any animals examined.The morphological changes on the reticular lamina and imprints by kanamycin treatment were observed in rabbits. When the outer hair cells were damaged by kanamycin, the degenerated hairs were seen on the imprints as well as the reticular lamina. It was thought that there were the firm junctions between the outer sensory hair tips and the under surface of tectorial membrane. The degenerated hairs on the imprints took longer period to disappear than those of the reticular lamina.The imprints have been observed for five months after the disappearance of the outer sensory hairs. However, their forms did not have changed at all morphologically.
