11. This enzyme helps produce hormones called cortisol and corticosterone . 12. Corticosterone levels correlated nicely to the survival data, increasing as survival rates decreased.13. Corticosterone is comparable to cortisol in this case.14. Corticosterone both inhibits protein synthesis and degrades proteins.15. Increased levels of corticosterone in chicks leads to increased begging for food and aggressiveness. 16. It can also act on aldosterone, corticosterone and cortisol, to some extent. 17. Corticosterone has further developmental effects on birds.18. It is a potent mineralocorticoid, with generally greater such activity than that of corticosterone . 19. Corticosterone is activated when the bird is exposed to stress, such as migrating great distances.20. As well, the rats showed increased corticosterone while experiencing stress during a serial memory task.
