Abstract

To date, most simulation studies involving measurement of the surface Laplacian have assumed that the medium containing the electrical sources is homogeneous. In this study, a layer of subcutaneous fat is included between the medium containing the sources and the surface where the surface Laplacian is measured. The effect of this layer, on the magnitude of the potential and surface Laplacian and on the accuracy with which the surface Laplacian can be measured, is considered
