Abstract
Three-dimensional reconstruction of the inner hair cells and their nerve endings of the guinea pig cochlea were performed from serial thin sections by means of computer graphics, and morphometric data was obtained. The methods for computer-aided reconstruction and morphometry were reported elsewhere.
The number of afferent nerve endings in the basal turn (average 25) was higher than that in the third turn (ave. 17). The majority of afferent endings (81%) were accompanied by the typical synaptic bodies in the hair cells, and several efferent endings were found to have synaptic contact with the inner hair cells.
