与在一个功能性核磁共振成像试验中一样,我们告诉迈克去仔细看人脸和其他东西。
And again in one of the functional magnetic insonance image experiments, we could ask Mike to examine faces verse other things.
科学家们同时利用功能性核磁共振成像和近红外光谱技术来监测受试者,观察他们大脑的升温模式,以此获得大脑的活动图像。
The scientists monitored the dreamers with both magnetic resonance imaging and near-infrared spectroscopy to see patterns of heat in their subject's heads, which gives a picture of brain activity.
因此,功能性磁共振成像可以确定确切的大脑位置和血流量。
So, fMRIs can identify both the exact location in the brain and the amount of blood.
