Figure 2.

The effect of feeding schedule on rest-activity rhythm during 7 days between the Night-Feeding group and the Day-Feeding group. (a and b) Representative double-plotted actograms show the activity patterns after feeding schedule in a 12 h:12 h light:dark cycle. The black sections in the actograms represent a greater amount of activity than the average value in 48 h, while the white ones represent less activity, the abscissa 8.00 means ZT0; 20.00 means ZT12. (c) Phase shift of acrophase. (d) Amplitude. (e) MESOR. (f) Diurnality Score. *P < 0.05 vs mean values in 7-day pre-feeding period; ^# P < 0.05 vs Night-Feeding group. Positive values represent phase advance, n = 8.
