Auditory efferents and phase locking

Dear List,

Might anyone know of any physiological and/or psychophysical studies that have investigated the role of the efferent system, specifically the MOCB, on IHC neural phase locking/perception of temporal fine structure? For the latter, I guess I'm looking for studies that might show changes in pitch perception of sinusoids and/or harmonic tone complexes - preferably containing only unresolved harmonics - and/or sound localisation abilities in patients who have undergone vestibular (and efferent) nerve sectioning.

On a more general note, is there are good reason to suppose that MOCB stimulation might improve the accuracy of IHC phase locking either in quiet or in noise?

Thanks for any help you can provide.

Cheers, José
