Neonatal environment can have important, life-long influences on stress-reactivity and hypothalamic-pituitary-adrenal (HPA) axis regulation. In rodents, brief mother-infant separations have been shown to improve efficiency of the HPA axis, decrease stress-reactivity, and decrease age-related declines in cognitive function. Here, we provide evidence that there are potential costs associated with improved ...
