The exploratory behavior was quantified of 72 h post mild traumatic brain injury (mTBI) animals relative to baseline measures. A paired t test indicated a significant difference in the average velocity (p = 0.0037), ambulatory distance (p < 0.0001), stereotypic counts (p < 0.0001), vertical counts (p < 0.0001), ambulatory episodes (p < 0.0001), and total velocity (p = 0.0004). Error bars represent standard deviation.
