Beschreibung:
Mammalian sleep comprises rapid eye movement (REM) sleep and non-REM (NREM) sleep. To functionally isolate from the complex mixture of neurons populating the brainstem pons those involved in switching between REM and NREM sleep, we chemogenetically manipulated neurons of a specific embryonic cell lineage in mice. We identified excitatory glutamatergic neurons that inhibit REM sleep and promote NREM sleep. These neurons shared a common developmental origin with neurons promoting wakefulness; both derived from a pool of proneural hindbrain cells expressing Atoh1 at embryonic day 10.5. We also identified inhibitory gamma-aminobutyric acid-releasing neurons that act downstream to inhibit REM sleep. Artificial reduction or prolongation of REM sleep in turn affected slow-wave activity during subsequent NREM sleep, implicating REM sleep in the regulation of NREM sleep.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hayashi, Yu -- Kashiwagi, Mitsuaki -- Yasuda, Kosuke -- Ando, Reiko -- Kanuka, Mika -- Sakai, Kazuya -- Itohara, Shigeyoshi -- New York, N.Y. -- Science. 2015 Nov 20;350(6263):957-61. doi: 10.1126/science.aad1023.
