Quinpirole-sensitive receptors are under circadian control. w1118 flies were decapitated at different time points during the 24-h period. Locomotion is expressed in mm per 2-min observation period starting immediately after 5 mM quinpirole application. Data are presented as mean locomotion of 30–50 flies tested at each time point (± SEM). (A) LD-entrained flies assayed 30 min after decapitation. One-way ANOVA shows a significant effect of the time of day on the amount of quinpirole-induced locomotion, (P < 0.001). (B) LD-entrained flies released into LL and tested after 25, 31, 37, 43, 49, and 55 h of constant light. One-way ANOVA shows the significant effect of the subjective time of day on the amount of induced locomotion (P < 0.001).
