Abstract

Although there is considerable research on the phenomenology, neuroendocrinology, neuroanatomy, and sensory control of maternal behavior; little is known about the influences of early postnatal and postweaning experiences onthe development of maternal behavior The pur-pose of this study was to assess how early life separation from the mother I at affects development of the off-spring's juvenile and adult maternal behavior: From postnatal Days Ito 17, 3 female rats within each litter were separated (SEP) from the mother and the rest of the litter for 5 hr daily while 3 of their sisters were not maternally separated (NSEP). On postnatal Day 21, all subjects were weaned and randomly assigned to one of three juvenile conditions. One female from both SEP and NSEP groups was either isolated (I), given a social conspecific (S), or given 1- to 4-day-old pups (P) for 5 consecutive days. Maternal behavior of SEP and NSEP animals was assessed and recorded on each of the 5 days. Once all animals reached adulthood, they were mated gave birth, and were assessed for their maternal behavior We found that the effects of maternal separation on juvenile maternal-like behaviors were minimal. On theother hand, maternal separation reduced adult maternal licking and crouching over pups. In addition, there was a significant interaction between postnatal and juvenile experience on maternal crouching in maternal animals. These results are discussed in terms of the variety of possible behavioral, endocrine, and neurochemical mechanisms that mediate the effects of early life experiences on adult maternal behavior (C) 2001 John Wiley & Sons, Inc.
