MASCO driven behavior rhythms in Per1/2/3 triple mutant mice.
Representative double-plotted actograms (the same mice shown in Fig. 2) of wheel-running activity of Per1/2/3 triple mutant mice given methamphetamine (MA; indicated by dotted lines to the left of the actograms) in their drinking water (0.005%) in constant darkness. Actograms are plotted with a 21-h period. All individual actograms are shown in Supplementary Fig. S10.
