Birds with increased levels of corticosterone will have slower feather growth during their molting period and an extended period of poor flight.
32.
Studies show that the modification of certain chemical and brain processes that affect corticosterone levels can also impact stress effects on memory.
33.
In studies on rats, the fluctuations of corticosterone concentration are shown to prevent stress impairment of recognition memory in lower amounts.
34.
In rodents, the lack of 17alpha-hydroxylase results in the synthesis of corticosterone instead of cortisol as in the human.
35.
Marine iguanas show higher stress-induced corticosterone concentrations during famine ( El Ni�o ) than feast conditions ( La Ni�a ).
36.
In certain animals such as rodents, the lack of 17alpha-hydroxylase results in the synthesis of corticosterone instead of cortisol.
37.
The rat hormone corticosterone is similar to cortisol, which is secreted under stress by the human adrenal gland, near the kidneys.
38.
Recent research shows that corticosterone inhibits the fat mobilizing effects of oleoyl-estrone in female rats that had their adrenal glands removed.
39.
Furthermore, these rats do not show an increase in their corticosterone while experiencing stress, demonstrating differing effects for differing brain regions.
40.
The last part is mediated either by the aldosterone synthase ( for aldosterone ) or by the 11?-hydroxylase ( for corticosterone ).
