Abstract
The surface Laplacian can give more localized information of the brain. A concentric bipolar electrode (consisting of a central disc and an outer annulus) can measure the surface Laplacian of the body surface electrical potential distribution. In this article we will study the feasibility of the Laplacian electrode for EEG from the problems of SNR, selection of the electrode parameter. And a new kind of active Laplacian electrode will be introduced to detect the visual evoked potential
