Abstract: In brain imaging, the accuracy involved in calculating scalp potentials due to cerebral electric sources depends on the realism of the head model. Existing methods assume homogeneous conductivity throughout each component tissue. This assumption introduces inaccuracies in computing the potentials. This paper proposes a new approach based on the use of pseudo-conductivity values in place of the uniform conductivity values assigned to tissues. Simulation results reveal that the conductivity values have a significant effect on the computed potentials, thereby invalidating the uniform conductivity assumption.
