Shown are the behavioral measures in the current experiment for which a significant difference between injured mice and sham controls was found. P values from analyses of variance (ANOVAs), power (1 – β) and calculated effect sizes (Cohen's d) are provided, and Cohen's d = . Effect size r for distance traveled in the EZM on day 21 was calculated as .

OF, open field; EZM, elevated zero maze; MBT, marble burying test.
