This paper investigates the influence of inhomogeneous head tissue conductivity on EEGs. A head model with inhomogeneity of radial and tangential conductivity is built up. Based on this model the EEG signals are calculated using the finite elements method. The results show that the inhomogeneous radial and tangential conductivity of skull tissue, which has been ignored so far, can cause about 5% difference compared with commonly used homogeneous conductivity head models.
