Chapter 4 examines the roles of oxytocin (OT) and olfaction in the maternal behavior of nonhuman mammals. It also presents an overview of brain anatomy. In concert with pregnancy hormones, the release of OT into the brain, derived from the paraventricular hypothalamic nucleus, stimulates the onset of maternal behavior. Although OT is not required for the maintenance of maternal behavior, it does enhance maternal behavior during the postpartum period in challenging environments by decreasing anxiety and increasing maternal motivation. OT, in the absence of pregnancy hormones, may also enhance maternal responsiveness in alloparents. For many postpartum mammals, maternal motivation is under multisensory control, and olfaction is not required, although it is necessary for maternal selectivity in sheep. In contrast, for laboratory mice, olfaction is essential for maternal motivation. For virgin female rats and rabbits, olfactory input from pups inhibits maternal behavior, but this inhibition is eliminated at parturition.
