Figure 1.

Effects of stress, mTBI, or the combination on open field activity. Activity was measured for 60 min at baseline (BL), and 3 and 5 days post injury and the number of beam breaks was collected. (A) Horizontal activity (measure of general health and movement) of the animals throughout the experiment. (B) Vertical activity (measure of depression-related behavior) of the animals throughout the experiment. Vertical activity measurement post injury was covaried for baseline measurements due to differences at baseline between groups. *p < 0.05, **p < 0.01 vs. Naïves, respectively.
