Abstract

Cochlear nuclei receive a dense noradrenergic innervation originating mainly from the locus coeruleus (Klepper and Herbert, 1991 ). We have previously documented the high turnover rate of noradrenaline in the antero-ventral cochlear nucleus (AVCN) and in the posterior part of the nucleus in Sprague-Dawley rat at the basal state level (Cransac et al., 1995).
