Abstract
Investigations in the cat, rat, and guinea pig have shown that two separate populations of neurons form the efferent innervation of the cochlea (Warr and Guinan, 1979; White and Warr, 1983; Strutz and Bielenberg, 1984). Auditory nerve fibers at the base of inner hair cells (IHC) are innervated by small neurons that are located in the region of the lateral superior olive (LSO) predominantly or exclusively on the ipsilateral side. In rat and guinea pig, these neurons are found within the LSO, in cat they are located close to the LSO mainly in its dorsal hilus. Because of the position of these neurons in the olivary complex it was called lateral system. Outer hair cells (OHC) receive their efferent innervation from a group of large neurons in several periolivary nuclei. This medial system is organized bilaterally in all species studied so far.
