The potential distribution in a layered anisotropic spheroidal volume conductor

Abstract

Formulas are derived that express the potential distribution in a layered spherical and spheroidal anisotropic volume conductor: the number of layers is arbitrary and each layer may be anisotropic. These expressions are a generalization of existing formulas for localization of sources underlying evoked potentials or electro-encephalographic data. The formulas are presented in a convenient form so that if they are applied in practice the likelihood of software errors is minimal.
