近年来,国内增添了诱发电位、CT,并将应用核磁共振。在过去的二十年中,脑的能量消耗可通过测定血流量以及测定氧和葡萄糖的消耗来加以研究。哥本哈根大学的研究工作是在阴极射线管照射时所产生的影像中看到在朗读或默读等特定的智力活动下脑部各部分的血液循环的迅速变化。 In recent years, the country has evoked potentials, CT, and will apply NMR. In the past two decades, brain energy expenditure can be studied by measuring blood flow and measuring oxygen and glucose consumption. The research work at Copenhagen University is to see the rapid changes of blood circulation in various parts of the brain under certain mental activities such as reading aloud or silent reading in the images generated when the cathode ray tube is irradiated.
