Time course of time spent tail chasing (A) and the number of rotations performed (B) in parental and transgenerationally stressed rats at 23, 19, and 15 hours prior to parturition. Tail chasing in control (n=7) and parental F0-S (n=6) dams increased from 23 to 15 hours prior to parturition. Note that there was no increase in tail chasing behaviours in transgenerational (F2-SNN, n=5) and multigenerational (F1-SS [n=5], F2-SSS [n=6]) stressed animals. Asterisks indicate statistical significances: * p≤0.05 and ** p≤0.01 in control dams, ^# p≤0.05 in F0-S dams, compared to the 23-hour time interval. Data represent mean square root±SEM.
