Moving behaviors of maternal rats in the open field test. Moving behaviors of maternal rats in the open field test at week 0 (W0) (A) and week 3 (W3) (B) are shown in Figure 2A and 2B. Moving behaviours of maternal rats from control group (C: n = 8) and CUS group (D: n = 12) in the open field test are shown in Figure 2C and 2D. Data are the mean ± S.E. * and ** indicate P < 0.05 and P < 0.01, respectively, as compared to the control group for the same week. ^# and ^## indicate P < 0.05 and P < 0.01, respectively, as compared to W0 for the same group.
