The inner hair cells are the sensory receptors while the outer hair cells are usually from efferent axons originating from cells in the superior olivary complex.

"' Lateral lemniscus "'in red, as it connects the cochlear nucleus, superior olivary nucleus and the inferior colliculus, seen from behind
33.
"' Climbing fibers "'are the name given to a series of neuronal projections from the inferior olivary nucleus located in the medulla oblongata.
34.
Math1, another transcription factor, is necessary for the appearance of VCN neurons in the cochlear extramural stream as well as the neurons of the superior olivary complex.
35.
The superior olivary complex is divided into three primary nuclei, the MSO, LSO, and the Medial nucleus of the trapezoid body, and several smaller periolivary nuclei.
36.
These neuronal electrical signals travel through neuronal axons to specific brain targets, such as the center of pupillary control called the olivary pretectal nucleus ( OPN ) of the midbrain.
37.
The axons from the second-order neurons cross the midline and ascend as the spino-olivary tract in the white matter at the junction of the anterior and lateral columns.
38.
There is evidence that each small cluster of nuclear cells projects to the same cluster of olivary cells that send climbing fibers to it; there is strong and matching topography in both directions.
39.
The superior olivary complex is located in the pons, and receives projections predominantly from the ventral cochlear nucleus, although the dorsal cochlear nucleus projects there as well, via the ventral acoustic stria.
40.
The axons of both cell types leave the AVCN as large tract called the " ventral acoustic stria ", which forms part of the trapezoid body and travels to the superior olivary complex.
