睡眠之谜（别名：shuimianzhimi ）由Terri,Randall主持执导,是一部扣人心弦的记录片。 NOVA: Mysteries of Sleep Like virtually every other animal, humans need sleep to survive. But why? What do we gain from spending nearly a third of our lives in such a defenseless state? And what's at stake if we sleep poorly? The functions of sleep have long been something of a mystery. But now scientists are peering deep into the brain to see what happens while we snooze. One study reveals that well-timed bursts of pink noise can nudge a person's brain waves, extending periods of slow-wave, or deep, sleep. And toddlers learning new words show that taking even a short nap after learning something new can help the information stick. And when it comes to sleeping poorly, it may turn out that having interrupted sleep can be just as harmful as missing sleep altogether. As scientists come to understand the powerful role that sleep -- or lack of it -- plays in everything from memory to trauma to emotion regulation, one thing is clear: This biological function is as crucial as it is complex.睡眠之谜更多精彩反同运动的前世今生玄奘大师大卫·克罗斯比：请以我的名字记住我舍她其谁共情光影：埃及剧院百年传奇P!NK：我所知道的一切戴夫·查普尔：淡定大上海的过客艾格妮捡风景：两年后成为：米歇尔·奥巴马自传
