The influence of dimension parameters on the performance of Body-surface Laplacian electrodes is studied in this paper. Some rules about the parameter optimization design are presented. The investigation suggests that the effective radius b should be equal to the inner radius of the ring electrode in order to reduce the relative error. Besides, in the(More)
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,(More)
