Time course of sleep parameters in flies that lived at least 73 days. Values are mean + SEM (eleven 30-min intervals averaged per each fly, and then averaged across all flies). Comparisons (Friedman test followed by Wilcoxon signed-rank test, p < 0.05) are between the 10-20 day period and all following ages: triangle (vs 35-45), circle (vs 60-70), square (vs 85-95), diamond (vs 110-120). Data are derived from the same flies used in Figures 5 and 6.
