Amygdala: Mean number of c-fos immunoreactive cells per 0.1 mm2 in the basolateral amygdala (BLA) and the central amygdala (CeA) of unpaired controls and trained rats after training (left) or after retrieval test (right). In the BLA, there was a significant increase in c-fos immunoreactivity in trained animals relative to controls after training. (**P < .005). There was not much difference in CeA after initial learning or retrieval and no effect of training in either condition.
