英语文章大意
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.

像其他任何地方你的身体细胞,神经细胞活性氧的利用.氧气的血液带来的神经元和神经元更积极的是,它会消耗更多的氧气.较活跃的大脑区域,更积极的神经元,反过来,更多的血液将前往该地区.并利用功能磁共振成像,科学家可以visualize3大脑的哪些部分得到更多的氧气丰富的血液-因此,这部分正在处理的信息.
一个功能磁共振成像机是一种装置,扫描大脑和血液流向大脑的措施变化.该技术显示大脑活动的变化研究如何当一个人的想法,看的东西,或者进行一个像说话或阅读活动.通过强调在工作中的大脑区域,当一个人在不同的图像看起来,功能磁共振成像可能帮助科学家确定与不同类型的图像相关的大脑活动的具体模式.
美国加州的研究人员测试了志愿者的看法有两个人一样,动物的日常物品图片数百,大脑的活动,和水果.科学家们使用了功能磁共振成像机来记录志愿者每次看着照片,他们的大脑活动.不同的对象造成了志愿者的大脑不同区域的光的扫描,显示活动起来.科学家利用这种信息来建立一个模型来预测大脑如何应付任何可能的眼睛看到的图像.
在第二次试验中,科学家要求志愿者看120个新的图片.像以前一样,他们的大脑进行扫描,每次他们在看一个新的形象.这一次,科学家们使用他们的模型,配合功能性核磁共振扫描图像.例如,如果一个扫描在第二次试验结果显示在第一次测试的大脑活动密切相关的是苹果的图片相同的模式,他们的模型预测,将有志愿者在寻找苹果.
