Schematic representation of the treatment design. The groups of rats were microinjected with atropine in the left or right SCN at 09.00 or 19.00 h during diestrus-1 (a), and the other groups were microinjected on the proestrus day (b). In panel c, note that the group of rats were microinjected with atropine in the left or right SCN at 09.00 h and at 14.00 h these rats were subcutaneously injected with 3.7 μg/kg synthetic LHRH. All animals were sacrificed on the predicted vaginal oestrus day
