Abstract
In mammals, all known auditory information enters the brain by way of the auditory nerve. The auditory nerve is a bundle of axons whose cell bodies are located in the spiral ganglion within the cochlea. The ganglion cells send peripheral processes out to the organ of Corti to contact acoustic receptor cells and send central processes by way of the auditory nerve to terminate in the cochlear nucleus. In this way, the ganglion cells convey the output of the receptors to neurons of the brain. In turn, cells of the cochlear nucleus give rise to the ascending auditory pathways. The role of the cochlear nucleus is to receive incoming auditory nerve discharges, to preserve or transform the signals, and to distribute outgoing activity to higher brain centers. In order to understand mechanisms of stimulus coding in these early stages of the auditory system, we need to know the nature of the signals conveyed by auditory nerve fibers and structural details of their destination in the cochlear nucleus.
