The present study was designed to investigate the role of the medial preoptic area (MPOA) and the bed nucleus of the stria terminalis (BNST) in the onset and maintenance of maternal behavior in sheep. In a first experiment, the MPOA or BNST were transiently inactivated during the first 2 h postpartum in primiparous ewes with the use of the anaesthetic(More)
Ewes form a selective olfactory memory for their lambs after 2 h of mother-young interaction following parturition. Once this recognition is established, ewes will subsequently reject any strange lamb approaching the udder (i.e. maternal selectivity). The present study tested the functional contribution of different amygdala nuclei to lamb olfactory memory(More)
Recent evidence indicates that reactivation of consolidated memories returns them to a protein-synthesis-dependent state called reconsolidation. The hypothesis that memories reconsolidate has never been assessed in social memory. The authors tested whether sheep (Ovis aries) mothers' memory of their lambs undergoes reconsolidation upon reactivation. After 7(More)
Sheep are able to discriminate photographs of conspecific faces. The present study investigates adult ewe's recognition of faces of the same animal between different ages or between different orientations. Twelve adult sheep were first trained to discriminate between faces of two unfamiliar animals, one of which was associated with a food reward. Transfer(More)
