[Tridimensional cartography of potential recorded on the human scalp: II. Calculation of current density by derivation of tridimensional interpolation function].
Scalp charge density or current density distributions may be computed from the electrical potential recorded from neighbouring electrodes. It can also be derived from an interpolating function in order to draw maps on which current sources can be seen more easily than on potential maps. We describe the computation of current density by derivation of a tri-dimensional interpolation function.
