Consciousness is one of the biggest mysteries of the brain.
意識(shí)是我們大腦最大的謎團(tuán)之一。
But maybe even more intriguing is what goes on when we lose consciousness—and how do we find our way back?
但更有趣的是，當(dāng)我們失去意識(shí)后，該如何再重新恢復(fù)呢?
Now, researchers studying anesthetized rats have discovered a handful of activity patterns that may help mark the path to consciousness.
現(xiàn)在，研究人員經(jīng)過研究被麻醉的老鼠發(fā)現(xiàn)，少量的活動(dòng)模式可以助我們找回意識(shí)。
The findings are in the Proceedings of the National Academy of Sciences.
這項(xiàng)研究已經(jīng)在《美國(guó)國(guó)家科學(xué)院院刊》上發(fā)表。
The anesthetized brain is not actually quiet.
麻醉過的大腦并不完全平靜。
It shows patterns of spontaneous activity that can change over time.
隨著時(shí)間的改變它會(huì)出現(xiàn)一些自主活動(dòng)模式。
But as the brain wakes, how do these random splashes of activity morph into the vigorous chatter of the conscious mind?
但是隨著大腦變得逐漸清醒，這些隨機(jī)自主活動(dòng)如何演變成精力充沛的大腦意識(shí)呢?
To find out, researchers looked for common patterns in the brain activity of rats as they were put under anesthesia and brought back.
為了尋找答案，研究人員觀察從被麻醉到恢復(fù)意識(shí)的老鼠。
And they discovered a number of patterns that took place consistently.
結(jié)果他們發(fā)現(xiàn)有大量的模式持續(xù)出現(xiàn)。
A few seemed to serve as stepping stones from deep anesthesia to waking, as if the brain were finding its way through a maze of possible activity states on the way back to consciousness.
并且其中一些像是為從深度麻醉到清醒準(zhǔn)備好的跳板，大腦如同通過一個(gè)可能處于活動(dòng)狀態(tài)的迷宮找尋恢復(fù)意識(shí)之路。
Knowing how the brain reboots itself may help physicians better predict recovery from brain injury or even coma, and should lead to a better understanding of how to keep us under.
了解大腦是如何自我恢復(fù)意識(shí)有助于幫助內(nèi)科醫(yī)生更好預(yù)測(cè)病人何時(shí)從腦損傷甚至昏迷中恢復(fù)意識(shí)。
