This paper investigates the effects of inhomogeneity and anisotropy on the EEG forward problem using spherical head models. The role of skull and brain anisotropy along with the effects of inhomogeneity in different layers of the spherical volume conductor have been quantified, numerically and analytically, using statistical modalities such as RDM, MAG and CC. The paper also investigates the effect of mesh density, selection of element type and role of adaptive mesh refinement on the accuracy and convergence of the finite element method.
