[New data on the physiology of the olivo-cochlear efferent systems].
The medial part of the olivocochlear efferent tract seems to be involved in two distinct phenomena. The crossed part is involved in the masking function and the uncrossed one in the control, through a tonic action, of the cochlear micromechanics.
