FIG. 5.

Head dips and U turns in the elevated zero maze. Female mice made more head dips than male mice on days 2 (A) and 21 (B) following injury. On day 2 following controlled cortical impact (CCI) (A), mice that had sustained severe CCI made fewer head dips than sham controls; however, on day 21 (B), all injured mice made more head dips than sham controls. The number of U turns in the zero maze was reduced in injured mice on day 2 following injury (C), but this measure was equal in all mice on day 21 (D). The asterisks (*) indicate an effect of sex, and the pound sign (#) denotes a significant effect of injury.
