Stress and the Adolescent Brain: Plasticity of Reproductive Behaviors in Female

Early life events influence life-long patterns of emotionality and stress responsiveness and alter the rate of brain and body aging.  Much research attention has focused on the programming effects of the hypothalamus pituitary axis (HPA) in early life and on understanding HPA function in response t...
