| These experiments examined the effects of NMDA-induced lesions of the amygdala and insular (gustatory) cortex (IC) on inhibitory avoidance learning and conditioned taste aversion (CTA) in rats. IC lesions, but not amygdala lesions, disrupted CTA. In contrast, lesions of either brain region disrupted inhibitory avoidance learning. These findings support the view that the IC is strongly involved in the acquisition of external as well as visceral aversively motivated behavior. Despite extensive functional interconnections, these 2 brain regions appear to have different roles in mediating different forms of aversively based learning. |
