　　Mind-reading1 Machine

A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what's happening in their brains.

When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons are responsible for this processing.

The fMRI (functional Magnetic Resonance Imaging ) 2 brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.

Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize3 which parts of the brain receive more oxygen-rich blood--and therefore, which parts are working to process information.

An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.

The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.

In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.

　　词汇：

scan v. &n. 扫描 visualize v. 使可见;设想

neuron n. 神经元

　　注释:

1. Mind-reading: 能读出(猜出)人的想法的。mind-read: 可做动词，如，As a successful

　　答案与题解：

1. C 文章第二段的最后两个句子提供了答案。Cells in your brain called neurons are

responsible for this processin9.这里的processin9指的就是上句中的内容。

2. D 的电容文章中没有出现。A的内容在第二段可找到。B的内容在第二段可找到。C的内容在第五段可找到。

3. A highlight：使…显得突出，标出。at work：正在工作的。这里指正在处理信息的'(大脑区域)。

4. B答案在文章的第六段中可以找到。实验者让两个自愿受试者观看许多照片，并用fMRI对设备测试他们的大脑在这一过程中的活动。

5.B A论述的范围太大。fMR技术已不再是梦想，所以C也不是正确选择。D所述内容与

文章完全不符。B符合文章内容，是最佳选择。

一个加州的研究团队开发了一种可以通过扫描人体大脑所发生的变化从而预测出这个人正在看一些什么样的物体的方法。

当你注视一些物体时，你的眼睛会发送一个关于该物体的信号到你的大脑中。大脑的不同区域处理眼睛发送的这些信号。大脑中负责这个过程的细胞叫做神经元。

FMBI(功能性磁振造影)脑扫描可以大体地比较大脑中人们对所观察物体基本形状的电运动。

像身体中其他地方的细胞一样，活跃的神经元细胞也需要氧气。血液为神经元提供氧气，神经元越活跃，对氧气量的需求越大。大脑中越是活跃的区域，它的神经元也就越活跃，为此，更多的血液会流经这一区域。那么通过使用FMBI，科学家可以使大脑中接收相对多的富氧血液的部分可视化。因此，可视化的部分就是处理信息的部分

FMRI机是一种可以扫描大脑和测量流向大脑的血液变化的设备。这项技术为研究者显示，当人们思考观察进行像说话阅读这样的活动时，大脑运动的变化。通过突出显示人们观看不同图像时头脑工作的区域，FMRI可以帮助科学家们确定与不同图像相关的大脑活动的具体形式。

加州的研究者让两个志愿者观察数百个诸如人、动物和水果这样的日常事物。他们用这样方式来测试大脑的活动。科学家使用FMRI机来记录志愿者看每一张图片时大脑的活动。显示这一活动时，不同物体会使志愿者大脑的不同区域在扫描时亮度增加。科学家利用此信息来建立一种模式去预测大脑对所看到事物可能如何反映。

在第二个测试中，科学家让志愿者看120个新图像。和以前一样，他们每看一张新图像时大脑都被扫描一次。这次，科学家用他们的模式来比较FMRI扫描的图像。例如，如果图像在第二次测试显示相同的形式的大脑活动，同时，该脑活动与在第一次测试中苹果图片有大关联，那么这个模式可能会预测出志愿者们正在看一些苹果。
