Behavioral changes are still present 45 days following a predator scent exposure. Activity of blast and control rats was assessed in an open field for 60 min at 45 days after the predator scent exposure. Shown are time in motion (A), total distance moved (B), center entries (C), center time (D), distance traveled in the center (E), and center rest time (F). Error bars indicate ±SEM. Asterisk(s) indicate statistically significant differences between blast-exposed and control [*p < 0.05, **p < 0.01, ***p < 0.001, a in (C) indicates p < 0.001, all comparisons unpaired t-tests].
