Noise-induced degeneration in the brain and representation of inner and outer hair cells.
Noise that destroys receptor cells in the chinchilla cochlea also results in degeneration of axonal endings in the brain from the cochlear nerve fibers and the auditory pathways ascending to the superior olivary complex and inferior colliculus. The patterns of degeneration provide experimental evidence for differential representation of inner and outer hair cells and their functions.
