缺血性脑血管病可导致脑皮质电生理改变.脑磁图(magnetoencephalography,MEG)可客观和敏感地检测皮质磁场,具有极高的时间和空间分辨率,并能定位磁场发生源部位.目前,MEG主要用于自发波检测以及体感诱发磁场、听觉诱发磁场、视觉诱发磁场和事件相关磁场的检测,也为缺血性脑血管病的皮质功能改变提供了有价值的信息,但还需要进一步深入研究.

Ischemic cerebrovascular disease results in electrophysiological changes of the cerebral cortex.Magnetoencephalography (MEG) can objectively and sensitively detect cortical magnetic field.It has a very high temporal and spatial resolution,and locates the magnetic field source.At present,MEG is mainly used for the detection of spontaneous wave and the detection of somatosensory evoked magnetic fields,auditory evoked magnetic fields,visual evoked magnetic fields,and event-related magnetic fields,and provides valuable information for cortex function changes of ischemic cerebrovascular disease.However,further study is still needed.
