Rats shifted from a high to a low concentration of sucrose make fewer licks for the low concentration than rats that experience only the low concentration of sucrose. This phenomenon, referred to as successive negative contrast, is eliminated after bilateral electrolytic lesions of the amygdala. Because the amygdala receives direct projections from the gustatory zone of the parabrachial nuclei of the pons (PBN), this experiment was designed to examine this phenomenon in 43 male rats with electrophysiologically guided bilateral electrolytic lesions of the PBN. The results of this experiment showed that lesions of the PBN fully prevent contrast in rats shifted from the high to the low concentration of sucrose. Thus, an intact PBN is essential for the occurrence of successive negative contrast effects in rats.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
