From: A non-circadian role for clock-genes in sleep homeostasis:a strain comparison
Significant correlations among forebrain expression levels of the four genes examined during control (left; n = 48) and sleep deprivation (SD; right; n = 48) conditions. Only those correlations between gene pairs are indicated that remained significant after partialling out the influence of the other two. In blue the Pearson's correlation coefficients, in red the partial correlation coefficients. Line thickness corresponds to correlation strength.
