This paper is focused on the sophisticated realistic head modeling based on inhomogeneous and anisotropic conductivity
distribution of the head tissues. The finite element method (FEM) was used to model the five-layer head volume
conductor models with hexahedral elements from segmentation and mapping of DT-MRI data. Then the inhomogeneous
conductivities of the scalp, CSF and gray matter tissue were distributed according a normal distribution based on the
mean value of respective tissues. The electric conductivity of the brain tissues dictates different inhomogeneous and
anisotropic at some different microscopic levels. Including the inhomogeneous and anisotropy of the tissue would
improve the accuracy of the MREIT, EEG and MEG problems in the simulation research.
