摘要

在这里，作者研究了一个用于脑磁图(MEG)或脑电图(EEG)逆问题的源模型。提出了一种对应于大脑皮层表面的二维扩散源模型。源的传播是通过在一个区域内定位许多偶极子来表示的。假设每个偶极子都具有时变矩，模拟脑磁图的时空模式。结果表明，震源的扩散对磁相图的波形有明显的影响。

A source model with 2-dimensional spread of electrical activity in the human brain

Here, the authors investigate a source model which is used in inverse problems of magnetoencephalography (MEG) or electroencephalography (EEG). A source model with a 2-dimensional spread which corresponds to the surface of the cortex is proposed. The spread of the source is expressed by locating many dipoles in a region. Assuming that the dipoles each have a time-varying moment, spatio-temporal patterns of magnetoencephalograms (MEGs) are simulated. The results show that the waveforms of MEG are affected significantly by varying the spread of the source.<>
