The basal HPA axis activity in bright-LD and dim-LD conditions. (A) Plasma CORT concentrations at ZT2 and ZT14. Two-way ANOVA revealed a significant effect of time (P < 0.01). (B) Relative CRH mRNA levels in the PVN at ZT2 and ZT14. Two-way ANOVA revealed a significant interaction between time and lighting conditions (P < 0.01). There was no significant difference in paired adrenal grand weight (C) or body weight (D) between animals housed in bright- and dim-LD. Results are shown as mean ± SEM. Numbers on each column indicate the sample size.
