Old myths die hard and this particular one has had a long life. Do we really use just 10% of our brain? Perhaps it's because it gives us hope. If 90% of our brain is free, well, we could do so much more with it. Like solve complex problems, multitask on an epic scale, or just levitate cats.
古老的神话很难消亡，而这个特别的传言已经存在了很长时间。我们真的只用了大脑的 10%吗？也许是因为这句传言给了我们希望。如果我们大脑的 90%还有待开发，那么，我们可以利用它做更多的事情。比如解决复杂的问题，进行大规模的多任务处理，或者只是让猫漂浮起来。
For the real answer, all you have to do is, well, think for a second. The brain is one of the most costly body parts to maintain It's only 1% of our body weight but uses 50% of our glucose reserve and 20% of the oxygen we breathe. Spending 90% of all this on cells that have no use would be totally inefficient. In fact, most of it is working away most of the time.
对于真正的答案，你所要做的就是，嗯，思考一下。大脑是维护成本最高的身体部位之一。它只占我们体重的 1%，却消耗了我们 50%的葡萄糖储备和 20%的氧气。把这一切的 90%都花在毫无用处的细胞上完全没有任何效率。事实却是，几乎整个大脑大部分时间都在工作。
Indeed even daily life requires our brains to work extensively as neuroscientist Sophie Scott tells the BBC's more-or-less program: In terms of sort of the way that it functions, your brain is working away all sorts of things you don't even necessarily realize that you're doing. So talking to you now, I'm sitting upright in a chair, I'm not falling to the ground and that's actually requiring quite a lot of postural control which is occurring in my brain.
实际上，即使是日常生活也需要我们的大脑大量工作，正如神经学家索菲·斯科特在 BBC 的“或多或少”节目中说的：就大脑的运作方式而言，你的大脑在处理各种你甚至都没有意识到自己在做的事情。此刻我跟你说话，我正直挺挺地坐在椅子上，我没有掉到地上，这其实需要相当多的姿势控制运作，而这正在我的大脑中发生。
And I'm also talking to you, listening to you, looking at you, moving my hands, and doing all sorts of different actions. Which are all and perceive your sorts of different things which are all being controlled by my brain. And on top of that, I'm thinking about what I want to say. I'm thinking about all sorts of other things that are going on immediately. That's still all being underpinned by your brain, that's also subconscious and unconscious stuff going on absolutely all the time.
而且我还在和你讲话，听你说话，看着你，移动我的手，做各种不同的动作。以上这些都和感知到你的各种不同状况有关，这一切都被我的大脑控制着。除此之外，我还在思考我想说什么。我在想所有正在发生的其他事情。这仍然要靠你的大脑来支撑，而且潜意识和无意识的思考也一直在进行。
Perhaps we shouldn't think about brain capacity, but how our brain changes. New skills don't take up brain space that wasn't used before. It's all about neuroplasticity. When we do or learn new things, we train our brain to act differently. We force it to create new connections within neurons and to lose the ones we don't need. Efficient, eh?
也许我们不应该考虑大脑的容量，而应该考虑我们的大脑如何变化。学习新的技能不会占用以前没有用过的大脑空间。这都是神经可塑性的问题。当我们做或学习新事物时，我们训练我们的大脑以不同的方式行事。我们迫使它在神经元内建立新的连接，并减少我们不需要的连接。效率很高，是吗？
But where does this 10% of our brain myth come from? Sophie Scott shines a light on its history. It actually comes from a self-help book from nearly a hundred years ago, and the idea there was sort of saying you can be more, you can do more with your life. And the particular unfortunate example they gave was you're only using 10% of the brain, you can do so much more if you use more of your brain. It seems to be absolutely endemic and it crops up in a popular culture.
但是，我们的大脑只开发了 10%的传言从何而来呢？索菲:斯科特为我们揭开了它的历史。这句话其实来自于近一百年前的一本自助书籍，其中的观点是说你可以做得更多，你可以用你的生命做更多的事。他们给出的一个特别不幸的例子是，你只使用了大脑的10%，如果你使用大脑的更多部分，你就可以做更多的事情。它似乎原本只是地方性的传播，可它突然出现在流行文化中。
So our brains are already amazing multitasking superheroes. Maybe we should think about how we can mold, transform and share it with others to achieve great things.
所以我们的大脑已经是了不起的超级英雄了，能兼顾多项事情。也许我们应该思考要如何塑造、改造并与别人分享它，以实现伟大的成就。
