Spontaneous locomotor activity of CREM-mutant mice
(n = 11) and wild-type littermates
(n = 11). Locomotor activity was measured at 14:00
on 3 consecutive days. On day 4, locomotor activity was recorded at
9:00, 14:00, 21:00, and 2:00. Values represent mean ± SEM.
★, P < 0.05, ★★,

t test); ⋆, P < 0.05,
⋆⋆, P < 0.01, vs. wild-type
group at the same time point (one-way ANOVA).
