  • Abstract
    Computer simulations of the reconstruction and imaging of neural currents from their external magnetic fields are presented. The method is based on the Fourier transformed Maxwell equations in combination with the Whittaker-Shannon sampling theorem. The simultaneous reconstruction of more than one current generator without any special physiological model assumptions of the current density distribution is discussed.
