Steroid hormone serum levels of the rats treated at 19.00 h on the proestrus day. The means ± the SEMs of the progesterone (ng/ml) and oestradiol serum levels (pg/ml) in the rats subjected to microinjections of vehicle in the left (Vh L-SCN) or right (Vh R-SCN) SCN or atropine microinjections in the left (ATR L-SCN) or right (ATR R-SCN) SCN at 19.00 h during proestrus. * p < 0.05 vs. their respective groups that were microinjected with Vh (Student’s t -test)
