Figure 1

The percent wake on the Y-axis is represented as a sliding average over a 2-h window. Hours of recording are plotted on the X-axis where 0 represents midnight of day 1. Dashed vertical lines demarcate the dark phase, which is also indicated at the bottom as a heavy horizontal black line. Each two plots were shown for A. cahirinus and Wild M. musculus to show similarities of the sleep–wake profiles of two randomly selected mice in each group. One plot was shown for each Lab M. musculus. (A) A. cahirinus female (n = 18). (B) A. cahirinus male (n = 18). Two Lab M. musculus. (C) Lab M. musculus (SW) female (n = 16), Lab M. musculus (BL6) female (n = 9). (D) Lab M. musculus (SW) male (n = 16), Lab M. musculus (BL6) male (n = 9). (E) Wild M. musculus female (n = 11). (F) Wild M. musculus male (n = 11).
