Both the magnitude and the duration of the hormonal stress response change dramatically during neonatal development and aging as well as with prior experience with a stressor. However, surprisingly little is known with regard to how pubertal maturation and experience with stress interact to affect hypothalamic-pituitary-adrenal axis responsiveness. Because(More)
The pubertal maturation of the hypothalamic-pituitary-adrenal (HPA) axis has received relatively little experimental attention. The present set of experiments sought to extend our understanding of the pubertal stress response by measuring corticotropin (ACTH), corticosterone, and testosterone levels in prepubertal and adult male rats exposed to a single(More)
Numerous studies have established that adolescence is marked by substantial changes in stress reactivity and hippocampal function. Glucocorticoid receptors (GRs) in the hippocampus are imperative in corticosterone-dependent gene transcription when glucocorticoid levels are relatively high, such as during periods of stress. As reported previously, in(More)
