Steroid hormone serum levels in the rats treated at 09.00 and 19.00 h during diestrus-1. Means ± SEMs of the progesterone (ng/ml) and oestradiol serum levels (pg/ml) in the rats subjected to microinjections of vehicle into the left (Vh L-SCN) or right (Vh R-SCN) SCN or atropine microinjection into the left (ATR L-SCN) or right (ATR R-SCN) SCN at 09.00 or 19.00 h during diestrus-1. *p < 0.05 vs. the respective groups microinjected with Vh (ANOVA followed by Tukey’s test). ♦p < 0.001 vs. ATR-L-SCN (ANOVA followed by Tukey’s test)
