Flies lacking <i>inc</i> exhibit reduced behavioral sleep homeostasis.

<p>The graph shows the percent change in sleep (%Δsleep) after 12 h of mechanical sleep deprivation (red), 6 h of sleep recovery (light blue), and 9 h of sleep recovery (dark blue) in <i>inc^f00285</i> (n = 45 females), <i>inc^mw</i> (n = 68 females), and iso31 (n = 41 females) showing that the homeostatic response to sleep loss is disrupted in <i>inc</i> mutants. Error bars are SEM. * p<0.05 with Student's t test.
