摘要
根据头皮记录到的多道脑电信号反演人脑内部电活动源的信息,是一个跨学科的交叉性课题,其研究成果将在探索人的感觉、认知过程及神经疾病诊断等方面具有重要作用.本文主要分析了目前有关脑电产生源求解问题中的几大类研究方法:基于等效偶极子源的参数定位法;基于电流分布源模型的图象重建法以及神经网络在源定位中的应用等,介绍了各自所取得的进展及其发展前景.
The determination of the electric activity sources within the brain from the potential distribution me-asured on the scalp is important in both basic neuroscience and clinical diagnosis of neurological disorders. Generally there are three solving methods in this field: parameters estimation based on equivalent dipole sour-ces , tomographic imaging reconstruction based on distribution current sources, and neural network approaches. This paper reviews the development and status about these three methods.
