Dp16 mice are more active during the light phase of a 24-hour period. (A) Locomotor activity over 24 h. (B) Total distance traveled during the dark phase (1900 h–0700 h). (C) Total distance traveled during the inactive phase (0700 h–1900 h). Locomotor activity in Dp16 mice is significantly increased compared to WT. Data shown: mean ± SEM. ^*p < .05. N = 4–7 mice/per time point/group (note: each group contained 7 mice, but some data were lost during recording).
