Tail chasing behaviour in parental and transgenerationally stressed rats from 14-15 hours prior to parturition. Prenatal and transgenerational stress reduced the amount of time spent tail chasing (A) and the number of rotations (B) in a 60-min time interval. There was no effect of gestational stress in the parental generation (n=6), however, both transgenerational (F2-SNN, n=5) and multigenerational (F1-SS [n=5], F2-SSS [n=6]) stress reduced tail chasing activity. Cont includes non-stress control dams (n=7). Asterisks indicate statistical significances: ** p≤0.01, compared to control group. # p≤0.05, ## p≤0.01, compared to parental F0-S generation. Data represent mean square root±SEM.
