title: COMPARISON OF EMOTIONAL RESPONSES IN MONKEYS WITH RHINAL CORTEX OR AMYGDALA LESIONS creator: Meunier, PhD Martine creator: Bachevalier, PhD Jocelyne subject: Neuropsychology subject: Animal Cognition subject: Primatology subject: Behavioral Biology subject: Behavioral Neuroscience subject: Animal Behavior description: Four emotionally arousing stimuli were used to probe the behavior of monkeys with bilateral ablations of the entorhinal and perirhinal cortex. The animals’ behavioral changes were then contrasted with those observed earlier (Meunier et al., 1999) in monkeys with either neurotoxic or aspiration lesions of the neighboring amygdala. Rhinal cortex ablations yielded several subtle behavioral changes, but none of them resembled any of the disorders typically seen after amygdalectomies. The changes produced by rhinal damage took mainly the form of heightened defensiveness, and attenuated submission and approach responses, that is, just the opposite of some of the most distinctive symptoms following amygdala damage. These findings raise the possibility that the rhinal cortex and amygdala have distinct, interactive, functions in normal behavioral adaptation to affective stimuli. date: 2002 type: Journal (Paginated) type: PeerReviewed format: application/pdf identifier: http://cogprints.org/2872/1/Emotion_2002.pdf identifier: Meunier, PhD Martine and Bachevalier, PhD Jocelyne (2002) COMPARISON OF EMOTIONAL RESPONSES IN MONKEYS WITH RHINAL CORTEX OR AMYGDALA LESIONS.
