From: Prolonged secretion of cortisol as a possible mechanism underlying stress and depressive behaviour
Differences between control monkeys and depressed monkeys.
(A) On the x-axis, individuals are divided into control monkeys (n = 18) and depressed monkeys (n = 23). The y-axis represents the monkeys’ ages (years). (B) On the x-axis, individuals are divided into control monkeys (n = 18) and depressed monkeys (n = 23). The y-axis represents mean frequencies of stressful events that the monkeys experienced per hour (f/h). (C) On the x-axis, individuals are divided into control monkeys (n = 18) and depressed monkeys (n = 23). The y-axis represents the mean frequencies of non-stressful events that the monkeys experienced per hour (f/h). (D) On the x-axis, individuals are divided into control monkeys (n = 18) and depressed monkeys (n = 23). The y-axis represents the mean levels of hair cortisol (μg/dl).
