Inhomogeneous tissue conductivity influence on the forward and inverse electroencephalogram problems in realistic head models

脑功能障碍指标很难获得，很大程度上是因为许多高级脑功能障碍反映的是脑功能异常，而不是明显的脑结构。本课题的神经元发生器定位与识别，将提供服务于高级脑功能的神经活动的来源和时间的补充信息，形成脑活动的时空序列图像。这将使磁共振成像的信息（空间分辨率高但时间分辨率低）和脑电图的信息（头皮上的时间分辨率高）结合起来，为临床心理学家和大脑研究人员提供更有效的诊断工具。

The brain dysfunction indicators have been extremely difficult to obtain, largely because many disorders of higher brain function reflect abnormalities of brain function rather than apparent brain structure. The neuronal generator localization and identification in this project will provide complementary information about source and timing of neural activities sub-serving higher brain function and form sequences of spatial-temporal brain activity image. That will enable the information from MRI, which has a good spatial but poor temporal resolution, and the information from EEG, which has a high temporal resolution on the scalp, to be combined to provide clinical psychologists and brain researchers a more efficient diagnostic tool.
