Auditory efferents and phase locking

[José Ignacio Alcántara <jia10@xxxxxxxxx>]

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
