Eight hungry rats previously rendered hyperphagic via hypothalamic parasagittal knife cuts did not differ reliably from eight sham-operated controls in their tendencies to feed upon the intact carcasses of freshly sacrificed conspecifics. The ventromedial hypothalamus is not an essential link in the neural circuit mediating the aversion of rats to feed on conspecific flesh.Hungry Norway rats exhibit an aversion to feed on conspecific flesh in the sense that, during a 1-h test, a large majority remain hungry rather than feed on a dead conspecific, whereas a large majority feed on a dead nonconspecific (e.g., a roof rat, Rattus rattus) rather than remain hungry (Carr, Landauer, Wiese, Marasco,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
