Facilitation of muricide by dorsal norepinephrine bundle lesions in olfactory bulbectomized rats.
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.
