Abstract
The surface Laplacian involves the second derivative of the potential. It will give different and perhaps more localized information concerning the sources that give rise to the surface potential distribution. In this article we study the SNR of the surface Laplacian, and figure out the measuring possibility of the surface Laplacian of some bioelectrical signals that never been mentioned by others
