Neurobiology of Mammalian Parental Behavior
Neural basis of parental behavior
Becoming a father: Behavioral switch from infanticide to paternal care
Virgin male mice often attack newborn pups (infanticide). After mating and cohabitation with a pregnant female, male mice shift to provide paternal care, even toward non-biological offspring. The accessory olfactory system and the rhomboid nucleus of bed nuclei of stria terminalis (BSTrh) are involved in infanticidal behavior.
Becoming a mother
Pup rescue under risk
Postpartum mothers exhibit a higher motivation to care for offspring. In the maternal MPOA, calcitonin receptor (Calcr) and its ligand amylin are upregulated, and facilitate maternal care under risky conditions.
