Figure 5 : Exploratory behavior in the open field..

Adult females were tested on the Open field. There was a significant decrease in (A) exploratory activity as well as (B) distance covered during the test on the mothers subjected to stress compared to the control females. (C) Thigmotaxis on female adults (tendency of animals to disproportionately explore the boundaries of an area) was also assessed in the open field. There was a significant decrease in time spent on the edges of the chamber from the stressed mothers compared to control. (t=2.353, *p<0.05). This might be due to the lack of motion detected while determining exploratory activity and distance travelled. Juveniles derived from stressed and undisturbed mothers presented similar (D) exploratory activity as well as (E) total distance travelled. However, the
litters from the stressed females spent significantly higher amount of time travelling on the edges of the open field (F), as compared to litters from the undisturbed females (t=1.745, *p<0.05).
