脑磁图研究的若干理论问题(下)——脑磁逆问题

Some basic theories on magnetoencephalographic research (Ⅱ)——magnetoencephalographic inverse problem

脑磁逆问题的求解是脑磁研究的一个重要方面 ,研究方法可分为两大类 ,即磁源重建方法及偶极子定位方法。本文从上述两个方面 ,较为全面地介绍了近年来国际上的一些主要研究成果 ,并对其中若干问题进行了详细的讨论。

Magnetoencephalographic(MEG)inverse problem solution is an important aspect on MEG studies.In general,the research approaches can be classified into tow different kinds of methods.One is called the magnetic source reconstruction,another is called current dipoles localization.In this paper,both methods are introduced throughly,including some important results achieved in recent years all around world.Especially,to several questions,detail discussion is given.Finally,some problems needed to be solved on current MEG studies and probable methods are also presented.
