The acetylcholine pathway has been proposed to be important for wakefulness and REM sleep, but genetic evidence has been missing. Using a knockout of acetylcholine receptor genes, Niwa et al show that Chrm1 and Chrm3 double knockout chronically diminishes REM sleep to an undetectable level and causes a severe short-sleep phenotype.
