Effects of early deprivation and maternal separation on pup‐directed behavior and HPA axis measures in the juvenile female rat

Juvenile female rats show maternal-like behavior toward pups. The purpose of the following experiment was to investigate whether the HPA axis, through the use of early separation manipulations that alter HPA functioning in rats, plays a role in the juvenile response to foster pups. Female rats were early deprived or maternally separated for 5 hours daily from PND 2 to 14 and compared to animal facility-reared rats. Deprivation or separation …
