摘要 基于头皮电位测量数据反向推导脑电活动源头信息 ,对研究脑神经电气活动规律、探索脑认知功能具有重要的科学意义和临床应用价值。本文详细介绍了脑电逆问题的研究现状 ,主要包括头模型、偶极子模型、正问题的算法和逆问题的求解 。 It is of great significance and clinical impor ta nce that detect the information of active sources inside the brain based on scal p potentials.In this paper we introduce the current state of the research on the inverse problem,which include the head model,the dipole model,the forward probl em and the inverse solution.And the global optimization algorithm is particularl y discussed.
