Natural variations of maternal care in the rat influence the development of neuronal systems that regulate defensive responses to threat. Thus, as adults, rats that received higher levels of maternal licking/grooming (LG) in infancy display dramatic reductions in burying in the shock-probe test, relative to offspring of low LG mothers. We sought to replicate that finding and determine whether maternal care similarly influences offspring responses to social threat, using the resident-intruder… CONTINUE READING
