Figure 3.

Correlation between activity bouts and activity duration in (A) male mice and (B) female mice injected with LPS or saline and measured at 1 or 3 h after injection. Activity bouts and activity duration were correlated in both male (r = 0.944) and female (r = 0.965) mice. Activity relative change scatter plot with box-and-whisker plot overlay of data from (C) male and (D) female mice. Male mice were injected with 12.5 mg/kg LPS or saline; female mice were injected with 6 or 12.5 mg/kg LPS or saline. Activity measured at 1 and 3 h after injections. **, Significant (P < 0.05) difference between groups; *, significant (P < 0.05) difference from baseline.
