A paper by Levine on this subject was published in the Proceedings of the Seventh International Tinnitus Seminar (2002), the second edition of which is now available from http://www.auditory.uwa.edu.au/ Regards, Greg O'Beirne <gobeirne(at)cyllene.uwa.edu.au> The Auditory Laboratory University of Western Australia > Robert Levine at the Massachusetts Eye and Ear Infirmary has noticed > that some of his patients can change, cease or initiate tinnitus with > jaw or neck movements. One theory on this may be that the Dorsal > Cochlear Nucleus is getting stimulated and is somehow communicating with > the Olivo-Cochlear Bundle and sending (or inteurrupting) effernet > signals to the cochlea via the outer hair cells. If the theory holds > that part of our ability to hone in on frequency estimation, and > therefore pitch, is related to this Olivo-Cochlear feedback loop, then > pitch shifts with massiter muscle contraction doesn't seem that far > fetched.
