Sex differences in body weight gains following amygdaloid lesions in rats.
Lesions of the most posterodorsal aspects of the amygdala resulted in equal weight gains (mean = 58 g) in male and female rats during a 22-day observation period. However, the absolute weight gains in the first 5 days after lesions were greater in females (+41.4 g) than in males (+18.8 g), as were the longer-term gains relative to their respective control groups. In a second study with female r...
متن کاملEffects of amygdaloid and amygdaloid-hippocampal lesions on object recognition and spatial working memory in rats.
Neurotoxic lesions of the amygdala did not affect the postoperative acquisition of a nonspatial test of object recognition (delayed nonmatching to sample) even when retention delays were increased from 0 s to 20 or 60 s, or when test stimuli were deliberately repeated within a session. Although these amygdaloid lesions did not alter forced-choice spatial alternation, they slightly increased neo...

متن کاملEscape latencies at three levels of electric shock in rats with amygdaloid lesions
Attempts to demonstrate active avoidance deficits in rats with amygdaloid lesions have yielded inconsistent results (Dicara, 1966; KembIe & Tapp, 1968; Robinson, 1963; McNew & Thompson, 1966). Recently, Bagshaw & Pribram (1968) showed that amygdalectomized monkeys had a lowered threshold for electric shock (as measured by the GSR) and failed to respond differentially to various US levels. The p...
متن کاملLatent inhibition of conditioned taste aversion in rats with amygdaloid or hippocampal lesions
The amygdala and hippocampus play crucial roles in the latent inhibition of different conditioned responses, such as fear conditioned. Nevertheless, the involvement of these structures in the latent inhibition of conditioned taste aversion (CTA) is uncertain. In the present study, we explore the relevance of the amygdala and hippocampus in latent inhibition using a CTA paradigm. The effects of ...
