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

大脑功能障碍指标一直非常难以获得，很大程度上是因为许多大脑功能较高的障碍反映的是大脑功能的异常，而不是明显的大脑结构。本项目中的神经元发生器的定位和识别将提供关于神经活动的来源和时间的补充信息，辅助服务于更高的大脑功能，并形成时空脑活动图像序列。这将使来自MRI的信息和来自EEG的信息相结合，为临床心理学家和大脑研究人员提供更有效的诊断工具。MRI具有良好的空间分辨率，但时间分辨率较差。

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.
