　　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.缉毒先锋一泡而红2011圣诞风暴大熊爱情CEO银线风暴爱情公寓番外篇：辣味英雄传 第二季拯救大明星彼得58大三元（粤语版）沙罗沙家店粮站圣母2015今年犯桃花约纳坦与狼共伍新奇武林外传贫穷贵公子傲骨贤妻 第三季超高效理论理科生坠入情网汉娜·蒙塔娜：电影版风味原产地·湖北犯罪现场调查：纽约第六季三个陌生的情人日落号列车黑色孤儿第四季挑战星期天再造民兵临床13区丁丁的影子：埃尔热不测风云大白鲨4飞来横财 2024七品神探明天会好的（独家幕后）谁与争锋九叔之古棺奇案1最后的车轮悲伤电影人之怒最后的愿望北斋2020
