Abstract
Localization of inositol phospholipids synthesis and metabolism in the cochlea was studied by means of autoradiography with 3H-myo-inositol . The most heavily labeled tissue was the stria vascularis. The nerve fibers of osseous spiral lamina and the synapses of outer hair cells also had many silver grains. The distribution of inositol phospholipids in any cells of cochlea was diffuse, but so far as cell membranes were concerned, the silver grains were most accumulated in that of outer hair cells. About the distribution of silver grains any differences among the each turns of cochlea were not found.
