Fig. 5.

Representative actigrams from each study. The movement patterns of mice from each study are recorded and analyzed. These figures are representative patterns of movements from mice of each study. Patterns are from the 10–20-min time point of testing. As shown, amphetamine (a) and GBR 12909 administered (b) mice exhibit increased activity levels in the mouse BPM compared to their respective controls. The increased activity also led to more straight distance-covering behavior (lower spatial d) in these mice
