Question: Do We Use Only 10% of our brains?
问：我们只用了我们大脑的10％吗？
This is one of the most commonly promoted and repeated phrase by motivational speakers and Many many others since the beginning of the last century.
自上个世纪初以来，这是最常被励志演讲者和许多其他人推广和重复的说法之一。
Today, however, Radiologist and Neuroscientists can look at any brain scan, measure brain activity at any given time and have a good laugh at the idea.
然而，今天，放射科医生和神经学家可以查看任何大脑扫描，测量任何特定时间的大脑活动，并对这一想法嗤之以鼻。
Imaging techniques, such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), allow doctors and scientists to map and watch brain activity in real time.
正电子发射断层扫描(PET)和功能磁共振成像(FMRI)等成像技术使医生和科学家能够实时绘制和观察大脑活动。
The truth is that your entire brain is playing its part.
事实是，你的整个大脑都在发挥它的作用。
If only 10% of the brain is normally being used, then damage to the other areas of the brain should not impair performance.
如果只有10%的大脑正常使用，那么大脑其他区域的损伤应该不会影响表现。
Instead, there is almost no area of the brain that can be damaged without loss of abilities.
然而，大脑中几乎没有任何一个区域可以受到损害但是仍然不丧失能力。
Even slight damage to small areas of the brain can have profound effects.
即使大脑的小区域受到轻微损伤，也会产生深远的影响。
Obviously, this is bad news for anyone hoping to find the secret to becoming a genius overnight.
显然，对于那些希望找到一夜成才秘诀的人来说，这是个坏消息。
The good news, though, is that hard work still works.
不过，好消息是，努力工作仍然奏效。
There is plenty of reason to believe that you can build brain power by regularly working at challenging mental tasks.
有足够的理由相信，你可以通过定期从事具有挑战性的脑力任务来增强脑力。
In fact, your brain is capable of Neuroplasticity: it is the ability of the brain to change continuously throughout an individual's life.
事实上，你的大脑有神经可塑性：这是大脑在一个人的一生中不断变化的能力。
