FIG. 8.

Variability in behavioral data. For each of the six sex and injury groups, the coefficients of variation are shown for 14 behavioral variables. Levene's test for the equality of variances indicated that there was no effect of sex or injury on the mean coefficient of variation (data not shown) and the distribution of variability was also unaffected by sex and injury. Open and closed symbols represent male and female mice, respectively. Circles, triangles, and squares represent sham, mild controlled cortical impact (CCI), and severe CCI, respectively. OF, open field; LDB, light dark box; EZM, elevated zero maze; MBT, marble burying test; SPT, sucrose preference test; FST, Porsolt forced-swim test.
