The hypothalamic-pituitary-adrenal (HPA) axis plays a dual role in the biology of developmental plasticity mammals, including humans—HPA activity not only provides input for, but is also target of, offspring plasticity. To investigate understudied effects exposure timing, this study quantified maternal HPA during each half gestation as well early lactation and assessed its effect on cross-sectional sample infant, juvenile adult Assamese macaques ( Macaca assamensis ). add ecological validity to experimental studies under laboratory conditions, were studied wild. Increased faecal glucocorticoid (GC) metabolite levels experienced gestation, postnatal associated with increased from infancy into adulthood. Building prior findings, indicates that significant timing influence presence, magnitude direction, consistency GC function.
