Figure 2. Sleep in male flies with up-regulated npfr1.

Figure 2

Sleep during the nighttime was significantly increased when npfr1 expression was enhanced (n=61 for controls, and 51 for yw; npfr1-Gal4/UAS-npfr1). (A) Daily sleep profile that showed increased sleep during the nighttime and the daytime in an npfr1 over-expressing line. (B) Average daily sleep profile over 4 days that revealed increased sleep during the night and the day. (C) Statistical analysis of sleep. Labeling is the same as that described in Figure 1.
