Duper and wild-type (WT) hamsters show small and comparable phase shifts in response to novel wheel confinements. Representative actograms of responses of (A) WT and (B) duper hamsters to novel wheel confinement at CT 0, 4, and 8 (open boxes) and to light pulses (vertical arrows) at CT 15 and CT 18.5 are shown. Actograms are plotted modulo τDD for each genotype. (C) Linear regression of phase shifts in circadian time on the number of revolutions during the novel wheel confinement at CT 0, 4, and 8. Significant correlations (*p < 0.03) were found at CT 0 and CT 8 in duper hamsters. The number of revolutions during confinement was similar in WT and duper hamsters.
