Abstract: A forward model of an electroencephalogram (EEG) is a necessary part of an EEG source analysis and plays a crucial role in accuracy of brain waves localization. The paper is aimed to exploit CST Studio Suite (CST) for an anisotropic forward model computation. Since the CST computes electric field intensity only, the line integration is used for the recalculation to the electric potential in MATLAB. The integration method and the accuracy of CST are validated by two software tools, and the comparison shows consistent electric potentials. Finally, the simplified anisotropic rat brain models are developed and simulated. Nevertheless, the anisotropic models compared with isotropic one show a rather weak effect on computed electric potentials.
