一种新的脑电逆问题求解方法

以"路"代"场",把脑电逆问题看成是从颅内大脑皮质层源电位到头皮实测EEG信号之间的电路网络传输,从能量守恒、动能位能的相互转换等普适性原理出发,建立了动态的电压平衡方程.用经验模态分解等方法反演计算出脑电生理学材料参数之后,通过求解该方程来确定脑电的源电位,为解决脑电逆问题提供新的途径.

A new method for EEG inverse problem solution

The paper considered the EEG inverse problem as circuit transmission from the source potential in cerebral superficial cortex to practical measured EEG signal over scurf.By studying from some universal principles,such as energy conservation equation,the transformation mechanism between kinetic energy and potential energy and so on,a dynamic voltage equilibrium equation is proposed.By using the empirical mode decomposition and other methods,the cerebral electrophysiology material parameters are inversion cal...
