用于定位大脑电活动的脑电图源定位一直是一个活跃的研究领域，因为它为研究大脑的生理、心理和功能异常提供了有用的信息。这个问题称为脑电图反问题。活动源的定位需要解决病态脑电逆问题。自该领域建立至今，已经开发了许多方法，以实现深度定位、高分辨率、减少定位/能量误差和减少计算时间。在本次调查中，讨论了脑电图逆问题及其主要到最成熟和最新的解决方案。提供了该领域的介绍以及不同解决方案的分类。此外，还讨论了每种方法的相对优点和局限性。最后，最后提出了脑电图反问题在分辨率、计算能力和定位误差方面的挑战和未来建议。 (C) 2014 Elsevier Ltd. 保留所有权利。
The EEG source localization which is used to localize the electrical activity of brain has been an active area of research as it provides useful information for study of brain's physiological, mental and functional abnormalities. This problem is called EEG inverse problem. The localization of the active sources needs the solution of ill posed EEG inverse problem. Since the foundation of this field till today, many methods have been developed with the aim of in-depth localization, high resolution, reduction in localization/energy error and decreased computational time. In this survey, EEG inverse problem is discussed with its primary to most developed and recent solutions. The introduction to the field along with the categorization of different solutions is provided. Also, the relative advantages and limitations for each method are discussed. Finally, the challenges and future recommendations are provided, in the end, for further improvement of EEG inverse problem in terms of resolution, computational power and localization error.
