[EEG potential theory in a model with thin brain integuments. I. Multilayer spherical cable model]

The problem of finding EEG potentials is solved assuming that integuments of the brain are regarded as infinitely thin spheres. The potential is not changed along the radius in the layers with high conductivity, and the current in the resistive layers is only radial. It is shown that the EEG potentials could be described exactly enough supposing the lower bone plate to be an ideal isolator. The potentials of EEG are obtainable from ECoG by means of a comparatively simple algebraic procedure.
