Abstract

The aim of the present study was to determine whether the 2-deoxyglucose uptake of amygdala slices was affected by olfactory bulbectomy. At 7, 14 and 21 days post-lesion, bilateral olfactory bulbectomized rats exhibited a significant increase of 2-deoxyglucose uptake in amygdala slices, but not in the cerebral cortex. In addition, unilateral olfactory bulbectomized rats showed a high uptake of 2-deoxyglucose uptake in the ipsilateral amygdala, but not in the contralateral amygdala. These results suggest that the enhancement of 2-deoxyglucose uptake is related to the hyperexcitability of amygdala neurons following bulbectomy, and that this enhancement may be responsible for the behavioral changes in olfactory bulbectomized rats.
