英语老师刘沧龙分享：通宵熬夜会让你的身体发生这些……
There are times when it's unavoidable - adissertation is due, a family member is in theemergency room, it's make-or-break for yourcompany - but you should be aware of just howdamaging pulling an all nighter can be for your body.
有时这是无可避免的--论文要交了，家人在急救室里，公司到了生死存亡的关头--但是你应该要知道开夜车会对你身体造成何种伤害。
Neuroscientists from Norway looked closely at thepotential repercussions on our health, and it's notpretty (as you might expect if you've ever suffered asleepless night).
挪威的神经学家仔细研究对我们健康的潜在负面影响，这不妙。（就像你可能预料到的那样，如果你曾经历过不眠之夜的话。）
They recruited 21 healthy young men to undergo a series of diffusion tensor imaging (or DTI) tests, which indicate water diffusion in the body and thus the health of the nervous system.
他们招募了21名健康的年轻男子进行一系列弥散张量成像测试（DTI），这项测试能显示水在体内的弥散，进而显示神经系统的健康程度。
The volunteers stayed awake for 23 hours, and to provide some control conditions, theyweren't allowed to consume alcohol, caffeine, or nicotine during the study, and theycouldn't eat anything before a DTI scan.
志愿者23小时保持清醒。为了提供对照组，他们在研究期间不被允许摄入酒精、咖啡因或者尼古丁，并且在DTI扫描前不能进食。
The 2015 report pointed to "significant" changes in the white matter inside the brain after anight with no sleep, finding that "sleep deprivation was associated with widespread fractionalanisotropy".
这份2015年的报告指向一夜未眠之后，大脑中白质的“巨大”变化。发现“睡眠剥夺与普遍的局部各向异性有关。”
In other words, a degradation of the 'connectivity' networks inside the brain - something youmight have felt first-hand if you've ever tried to collect your thoughts after a sleepless night.
换句话说，就是脑内“连接”网络的恶化--如果你曾在不眠之夜后试图聚集自己的想法，这就是你可能切身体会到的东西。
Changes were noticed throughout the brain, covering the corpus callosum, brainstem, thalamus, fronto temporal and parieto-occipital tracts.
脑中各部位都能看到变化，包括胼胝体、脑干、丘脑、额颞和顶枕束。
What's not quite as clear is how permanent this damage is: could a long sleep the next nightrepair all the damage that's been done, for example?
尚不清楚这种损伤会持续多久：例如，下一晚的长时间睡眠能修复已造成的所有损伤吗？
