title: Changes in rat brain norepinephrine levels and turnover after olfactory bulbectomy.
abstract: After bilateral olfactory bulbectomy in rats a significant increase of norepinephrine (NE) level in the hypothalamus was found. However, no difference was observed between hypothalamic NE turnover of bulbectomized and sham operated animals in the amygdaloid cortex the NE level was not affected by bulbectomy. In this area, however, the NE turnover appeared to be decreased after bulbectomy. The latter finding may be related to the deficits in passive avoidance behaviour as found in bulbectomized rats.
