Figure 5.
Quantitative estimates of (A) water and (B) food intake during the photo- and scotophase in WT, Y2−/− and Y4−/− mice. The bars represent the water and food consumption summed up and averaged for the photo- and scotophase, respectively, of experimental days 1 and 2. Water consumption is expressed as ml/g BW, and food intake as g/g BW. The values represent means ± SEM, n as indicated below the abscissa. ** P ≤ 0.05 vs. WT mice, ++ P ≤ 0.05 vs. respective parameters in Y4−/− mice (Mann-Whitney U test).
