Abstract

We have developed a new algorithm to estimate the surface Laplacian of the scalp potential on a realistic geometry scalp surface. The performance of the algorithm was evaluated by computer simulations. The algorithm was applied to study the scalp Laplacian maps of visual evoked potentials induced by pattern onset stimuli in a human subject. The present results indicate the excellent performance of the newly developed algorithm and its potential for application in imaging brain electrical activity.
