The neurobiology of infant maternal odor learning

Abstract: Infant rats must learn to identify their mother’s diet-dependent odor. Once learned, maternal odor controls pups’ approach to the mother, their social behavior and nipple attachment. Here we present a review of the research from four different laboratories, which suggests that neural and behavioral responses to the natural maternal odor and neonatal learned odors are similar. Together, these data indicate that pups have a unique learning circuit relying on the olfactory bulb for neural plasticity and on the hy… Show more

“…Statistical significance was found for PN14 ( F (2,23) = 41.170, p < 0.001, n = 8/group) but not PN23 (all S.E.M. = 0), which replicates previous data from the lab (Raineki et al, 2010). Fisher’s post hoc tests revealed that when maternal odor was infused into the testing environment, pups showed significantly shorter latencies to nipple attach relative to groups when acetophenone or no odor was presented ( p < 0.05).…”

“…The correlation between cellular and perceptual effects of neuromodulators has been comparatively more extensively investigated in the OB; as a consequence, more detail about the role of neuromodulators in the OB will be provided compared to other structures. Neonatal olfactory learning in rodents, for which neuromodulatory systems are especially crucial, has been extensively reviewed elsewhere and will not be included in the present review [14, 15]. …”

“…Odors paired with stimuli mimicking maternal care are associatively acquired through the pairing of odor activation (conditioned stimulus, CS) and activation of the noradrenergic locus coeruleus (unconditioned stimulus, UCS) (Moriceau et al 2009;Raineki et al 2010;Landers and Sullivan 2012). Direct stimulation of b-adrenergic receptors in the olfactory bulb concomitant with novel odor is both necessary and sufficient to initiate odor preference learning (Sullivan et al 2000).…”
