Effects of pre-gestational stress on performance of offspring rats in the force swimming test. The floating time (A) and active (swimming or climbing) time (B) of offspring rats from different groups (female offspring in the control group, n = 24; male offspring in the control group, n = 24; female offspring in the CUS group, n = 30; male offspring in the CUS group, n = 30) in the force swimming test are shown. Data are the mean ± S.E. ** indicates P < 0.01 as compared to offspring rats in the control group of the same sex; △ and △△ indicate P < 0.05 and P < 0.01, respectively, as compared to male offspring rats with the same treatment.
