Brain electric source imaging: scalp Laplacian mapping and cortical imaging.
This article reviews recent progress in high-resolution EEG methodologies, in particular two widely studied approaches: scalp Laplacian mapping and cortical imaging. The common theoretical background behind these two high-resolution EEG approaches is discussed. The state of the art of the two methodologies are reviewed with examples illustrating their applications in imaging brain electrical activity. The emphasis is placed on the treatment of the mathematical and engineering methods of high-resolution EEG techniques, and reviews of our recent research in both scalp Laplacian mapping and cortical potential imaging.
