Noradrenaline depletion of the olfactory bulbs induces cannibalism at parturition in primiparous mice, without producing anosmia or impairment of maternal behaviour. Similar lesions made in multiparous experienced females do not result in cannibalism. The present studies investigated 1) whether a 30-min exposure to pups or to distal cues from pups given to virgin females before noradrenaline depletion of the olfactory bulbs overcame the impairment in recognition at first parturition, and 2) whether noradrenaline-depleted females allowed to care for their pups for the 24 h following parturition showed a failure in recognition on a second parturition. Experiment 1 showed that exposure to distal cues from pups enabled the females to successfully recognize pups at parturition in comparison to naive females. However, neither the exposure to pup cues nor the fully interactive experience with pups overcame the disruptive effect on recognition at birth of the noradrenaline depletion. In Experiment 2, we found that olfactory recognition was impaired in noradrenaline-depleted females on second parturition, in spite of the mothering experience with their own pups.
