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.

大脑功能障碍指标非常困难，主要是因为许多较高大脑功能的疾病反映了脑功能异常，而不是明显的大脑结构。该项目中的神经元发生器的定位和识别将提供有关神经活动的来源和时间的互补信息，从而超出了较高的大脑功能，并形成了空间脑脑活动图像的序列。这将使MRI的信息能够结合使用，该信息具有良好的空间但较差的时间分辨率，而EEG的信息（在头皮上具有很高的时间分辨率）可以合并为临床心理学家和脑研究人员提供更有效的诊断工具。
