00:11Sleep. Its something we spend about a third of our lives doing, but do any of us really understand what its all about? 睡眠 占用了我们一生三分之一的时间但是真正有人知道它到底是怎么回事吗？ 00:19Two thousand years ago, Galen, one of the most prominent medical researchers of the ancient world,proposed that while were awake, our brains motive force, its juice, would flow out to all the other parts of the body, animating them but leaving the brain all dried up, and he thought that when we sleep, all this moisture that filled the rest of the body would come rushing back, rehydrating the brain and refreshing the mind. Now, that sounds completely ridiculous to us now, but Galen was simply trying to explainsomething about sleep that we all deal with every day. See, we all know based on our own experiencethat when you sleep, it clears your mind, and when you dont sleep, it leaves your mind murky. But while we know a great deal more about sleep now than when Galen was around, we still havent understood why it is that sleep, of all of our activities, has this incredible restorative function for the mind. 两千年前古时候的名医伽林提出当我们醒着的时候我们大脑的原动力，它的液体会流动 到身体所有其他部位维持它们的活力，但这却使大脑枯竭并且他认为，在我们睡觉的时 候这些充满了我们身体其他部位的液体会再回到我们的大脑为大脑补充水分并且使我们 更有精神虽然这些观点如今我们听来很荒谬但是伽林很好的解释了那些我们每天都要面 对的睡眠的事情那么，根据自身的经验我们都知道如果我们睡觉了，我们的头脑会变的清 醒而如果我们没有睡觉大脑就会变糊涂我们现在对睡眠的了解 比伽林那个时期多了很 多但是我们仍然不知道为什么在我们所有的活动中，只有睡眠有如此这般可以促使我们 头脑变得清晰的功能 01:17So today I want to tell you about some recent research that may shed new light on this question. Weve found that sleep may actually be a kind of elegant design solution to some of the brains most basic needs, a unique way that the brain meets the high demands and the narrow margins that set it apart from all the other organs of the body. 所以今天，我想给大家讲一些近期的研究这些研究可能会揭示这些问题。我们发现，睡眠 实际上可能是对大脑的一些最基本的要求 的一种简洁的解决方案，是大脑满足身体高需求 的一种独特的方式。这种独特的方式 将它与我们身体其他器官区分开来。 01:41So almost all the biology that we observe can be thought of as a series of problems and their corresponding solutions, and the first pr
