Abstract
Corticotrophin-releasing hormone (CRH) immunoreactivity was detected i n neurons of the central nucleus of the amygdala that were retrogradel y labelled by injection of a fluorescent tracer (True Blue) into the p araventricular nucleus of the hypothalamus (PVN). The double-labelled neurons were located mainly in the medial subdivision of the central n ucleus and appeared to comprise less than one-fifth of the descending pathway. These results suggest that CRH may act as a neurotransmitter in the amygdalo-hypothalamic pathway.
