Abstract
Our knowledge of auditory efferents has changed greatly over the past few years. A new conception of the anatomical organization of the efferents has been developed and it has been demonstrated that efferents can produce mechanical changes in the cochlea. These, in turn, have motivated experiments intended (1) to determine the cochlear effects produced by each of the new efferent groups and (2) to determine the nature of the mechanical changes produced by efferents. In this paper, I review some recent experiments and the substantial changes which they have produced in our understanding of the physiology of olivocochlear efferents.
