title: Scalp current density fields: concept and properties.
abstract: The physical meaning of scalp current density (SCD) is presented and its properties are described using simulations of brain generators by dipolar models inside an inhomogeneous sphere. Its properties are compared with those of potentials and magnetic fields.
