Fig. 3: Comparison of sleep parameters between the light and dark phases.
From: Quantitative investigation reveals distinct phases in Drosophila sleep
a Distribution of β (active index). b Distribution of N (number of times the fly fell into sleep phase in 3 days). c Distribution of λ (sleep duration in seconds). d Distribution of K (sleep latency). e Distribution of total sleep time in 3 days. Each panel of (a–e) shows the statistical test (two-sample t test) results of the significance level of difference between male and female and/or in the light phase and dark phase, as indicated. Error bars indicate SEM of five biologically independent experiments. f–j The distribution of each index with histograms. Hollow columns represent the light phase, filled columns the dark phase. The blue columns represent male (n = 153), and the red columns female (n = 126).
