Abstract

The author considers the enhancement of spatial resolution with cortical imaging. The following topics are considered: cortical-potential imaging from scalp potentials; cortical-potential imaging from scalp Laplacians; equivalent surface-source imaging; cortical-potential imaging in a realistically shaped, inhomogeneous head model; inverse-imaging algorithms; other EEG-based cortical-imaging approaches.
