What regulates the urge to sleep? William Joo and colleagues identified brain regions that reflect how long mice have been awake. Strikingly, inhibiting one of these regions reduces sleep by 70%, without the major behavioral deficits associated with sleep deprivation. www.nature.com/articles/s41...
