Line Plot from Scientific Research

Activation of the dFSB using 23E10-LexA, a weaker transcriptional activator, selectively increases sleep at night but not the day. Top: sleep in 30-min bins during the second baseline day, 24 h of activation (as indicated by the red bar), and the first recovery day. Middle: locomotor activity in 30-min bins during the second baseline day, 24 h of activation (as indicated by the red bar), and the first recovery day. Bottom: daytime sleep from ZT0 to 12, nighttime sleep from ZT12 to 24, and evening anticipation index (computed by the Harrisingh index) (n= 40–43). For all panels, *p< 0.05,**p< 0.01,***p< 0.001 by Kruskal-Wallis with Dunns multiple comparisons between the experimental and UAS or LexA control (represented by the black asterisks) and the experimental and the Gal4 or LexA control (represented by the blue asterisks). For line plots showing activity or sleep profiles in 30 min bins distributed over ZT, lines represent means and error bars represent SEM. For box and quartile plots, data are shown representing medians and interquartile ranges, with outliers defined as those whose distance from the median is at least 1.5 times the interquartile range.
