Up next today, according to the Centers for Disease Control, it`s something that kills more than nine people in the U.S. every day and injures more than 1,100 nationwide. Car crashes when a distracted driver is reportedly involved.

下一条新闻，根据疾病控制中心的调查显示，这件事情，致使美国每天有超过9人死亡，100多人受伤。而这件事所涉及的人是车祸时分神的司机。

Now, many people will hear that and think texting. But distractions far simpler than messages can keep the brain from focusing on the road.

现在，很多人会听到短信、想发短信。但是短信非常容易让大脑分神，无法集中关注路况。

We often take driving for granted, until something goes wrong, and then we think, what were we thinking?

我们经常认为开车是理所当然的，直到发生了事故，到那时我们才想，我们当时在想什么呢?

Because driving involves your hands, your feet, your eyes, your ears, but it`s the brain the controls the action. In fact, driving uses about 20 different parts of your brain and distracting even one of those and the job at hand can be dangerous.

因为开车需要手、脚、眼、耳配合，但是控制行为的是我们的大脑。事实上，开车需要动用大脑20多个部位，但是只是手离开工作岗位的，情况就非常危险。

Let me show you what I mean: everything you`ll see while driving is handled here by the occipital lobe, while the temporal lobe interprets the sounds that you hear. So, taking your eyes off the road or turning off the music can really affect that input. You see that was close.

让我跟你展示下：开车时，你看到的所有事物都是经过枕叶处理的，枕叶解释了你所听到的声音。所以，你的眼睛不看道路或者仅是关一下音乐都会影响信息处理。你看距离前面一辆车的距离很近了。

Measuring distance between cars changing lanes, deciding on how to stop, that`s a job of a parietal lobe. It integrates data from all of your senses. It`s activated when you switch your attention from one thing to another. But it too can be easily distracted.

顶叶的工作是估量改变车道车辆之间的距离、决定停车方式。它集成了你感官的所有数据。当你将注意力从一件事转移到另一件事上，顶叶就被激活了。但是它也容易被分散。

For example, just listening to someone talk reduces the activity of the parietal lobe by nearly 40 percent. That affects how you drive. While talking on the cell phone and driving, even with an earpiece, that was said by researchers to be a recipe for disaster, especially if you`re turning in to oncoming traffic.

例如，仅是听别人说话就可以减少顶叶40%的活动。这就会影响开车。在开车时接听手机，即使带着耳塞，研究人员将这种行为成为灾难性行为，尤其是你重新注意到迎面开来的车辆。

I bet you`re thinking. So, if the brain needs to focus so much, why does driving seem so automatic? Well, it`s you`ve imprinted those motor skills in your brain is part of procedural memory. It`s your brain on autopilot. It allows you to focus on the more important things, like getting home safely.

我敢肯定你在思想。如果，大脑需要关注这么多的事情，那么为什么驾驶似乎是自动的呢?好吧，这是因为你的记忆力，大脑张运动技能程序性仅的一部分。这就是你的自动驾驶仪。这样你可以将重点放到更加重要的事情上，例如，安全到家啦。
