在测试中,志愿者被要求观看一系列的幻灯图片并进行记忆,研究人员同时用功能性核磁共振扫描仪对他们进行跟踪,获得血液流通和大脑活动的三维图像。
The test involved looking at and remembering a large set of picture slides while the volunteers were screened by fMRI scanner , which gives a3-D image of blood flow , hence of cerebral activity .

只用核磁共振扫描仪里的磁铁来检测寄生虫产生的废物。目前这种磁铁需要书桌大小的设备来支持工作,但是新加坡与麻省理工学院学术联盟的研究人员认为,他们可以将该设备缩小至平板电脑的大小。
Instead , it uses the magnets like those found in an MRI scanner to measure a waste product the parasite makes . Right now the magnets require a desktop-size device to work , but the researchers from the Singapore-MIT Alliance for Research and Technology think they can reduce that to the size of a computer tablet .
