Single housing does not affect weight gain due to CORT treatment, and CORT treatment results in hyperphagia. A, Weight change in response to CORT is largely unaffected in single-housed animals, with high-CORT animals still showing a significant weight gain compared with both other treatments. Although low-CORT animals seem to have a slight weight decrease, these differences are not statistically significant. B, Food consumption is altered by CORT treatment, with high-CORT animals showing a significant increase of the amount of food consumed over the 4-wk treatment period. C, High-CORT animals consume more food per gram of body weight per week than either vehicle or low-CORT animals. Asterisks indicate statistical significance at the P < 0.05 level. Bars sharing the same letter are not statistically different from each other.
