Abstract excerpt

Glucocorticoids (GCs), such as cortisol, bind to receptors in most tissues, triggering a stress response that enables individuals to adapt to stressors physiologically and behaviorally. GC signaling has been associated with plastic, stress-induced epigenetic modifications. However, the epigenetic profiles of individuals with divergent cortisol reactivity before and after a common challenge test have rarely been...
