| Upon stimulation, the rats suddenly released the stress hormone corticosterone, very like the cortisol humans release under stress. |
| Chicks given implants of corticosterone beg more than controls resulting in parents foraging to bring more food. |
| Working with mountain chickadees caught in California, he has inserted implants that release corticosterone, a hormone associated with stress. |
| Blood tests revealed comparable baseline concentrations of the stress hormone corticosterone in cautious and bold rats. |
| Melatonin and corticosterone are integral to the regulation of daily activity cycles in birds. |
| Note from the text of the full paper that stress causes the release of the hormone corticosterone which lowers latent inhibition. |
