title: Facilitation of muricide by dorsal norepinephrine bundle lesions in olfactory bulbectomized rats.
abstract: The role of the dorsal norepinephrine bundle in the occurrence of muricide was studied in olfactory bulbectomized rats. Although the incidence of muricide was 30% in the olfactory bulbectomized rat, it significantly increased up to 80% and 90% on the 5th and 10th day, respectively, after dorsal bundle lesion. Cortical norepinephrine content decreased by about 50% after dorsal bundle lesions. These results indicate that the dorsal bundle system plays an inhibitory role in the occurrence of muricide in olfactory bulbectomized rats.
