The Effect of progesterone and progesterone receptor antagonist on the time spent and the distance traveled on the elevated narrow path prior to trauma, on day of trauma (d0), first (d1), and second days (d2) after the brain trauma (n = 6 rats per group). Every bar represents the mean±SEM. A. ^***P < 0.001 compared with sham group on d0, d1, d2 times. ^### P<0.001 compared with oil group on d1, d2 times. B. ^† P<0.001 compared with VEH+P4 group on d1 time. C. ^*** P<0.001 compared with Sham group on d0 and d1 times. ^* P<0.05 compared with Sham group on d2 time. ^# P<0.05 compared with oil group on d1, d2 times. D. ^† P<0.05 compared with VEH + P4 group on d1 time

VEH: Vehicle; P4: Progesterone; RU + P4: RU486 + progesterone; TBI: Traumatic brain injury
