Representative double-plotted ethograms for wheel-running activity, food intake, rewarded-left-nose poking activity, and unrewarded-right-nose poking activity are shown with percentile plot

Data are plotted in 6 min bins, quantiles = 50. Light and dark condition is presented on the left half of the panel (white: light, gray: dark). Time when food was available is presented with an orange line on the left half of the panel. First blue asterisk: time when a microswitch position was fixed after it broke. Second blue asterisk: time when a microswitch was replaced. The times when cages were changed are indicated as #.
