Effects of TBI induction time on bodyweight, neurobehavioral damage, and survival. a Bars represent the means ± standard errors of bodyweight losses 24 h after TBI induction at different times of day; *P < 0.05 vs control group at the same hour, ^#P < 0.05 vs TBI group at 21:00 h. b Bars represent the means ± standard errors of neurobehavioral test scores obtained 24 h after TBI induction at different times of day; *P < 0.05 vs control group at the same hour, ^#P < 0.05 vs TBI group at 01:00 and 21:00 h. c Bars represent the survival rates observed over a 24-h period following TBI induction at different times of day. n = 7–10 per timepoint in each group
