Abstract

The cochlear nucleus (CN), as the first brain centre in the auditory system and is responsible for sorting the neural signals received from the cochlea, into parallel processing streams for transmission to the assorted higher auditory nuclei. A commissural connection formed between cochlear nuclei through direct projections, thereby provides the first site in the central auditory system at which binaural information is able to influence the ascending auditory signal. This restricted review investigates the nature of commissural projections and the impact of their input upon neurons of the CN through intracellular and extracellular electrophysiological recordings together with both acoustic and electrical stimulation of the contralateral KN. It also investigates electrophysiological, histological and neurochemical features of CN and commissural projections.
