Fig 1. Low and mild stress.

Fig 1

Peak (mean ± SD) ACTH (left) and cortisol (right) collected under low stress (home cage, A) and mild stress (primate chair, B) conditions. The mild stress condition reliably elevated both ACTH and cortisol for all animals across all social ranks and phases. Dominant animals had higher cortisol than intermediate and subordinate animals under the low stress condition (*: p < 0.05). Social housing potentiated the cortisol response to mild stress across all social ranks (#: p < 0.01).
