Abstract
In all cats surviving intracranial section of the 8th nerve, the cochlear response to sound stimulation, led off from the bony cochlea, was unchanged so far as the recording apparatus (a 2-electrode 3-stage amplifying set-up) indicated, even when serial sections showed complete degeneration of the cochlear ganglia with the nerve elements and efferent nerve fibers. These results indicate that nervous elements in the cochlea, at least in the ganglia, play little if any role in the production of the cochlear response, but throw no light on the question as to the living tissue or non-living structure origin of the response.
