Abstract

The purpose of the present study is to examine the effects of the White Matter (WM) anisotropy on the scalp electroencephalogram (EEG). The finite difference method (FDM) was used to model the head volume conductor with three kinds of inhomogeneous and anisotropic WM conductivities estimated by the volume constraint method. A current dipole was used to simulate the brain electrical activity with varying locations and orientations within the Gray Matter (GM) of the cortex. The present computer simulation results suggest that the anisotropic conductivity of WM may have some effects on the scalp EEG. Further investigations are needed to fully address this issue.
