Abstract

The cortical imaging approach shows great promise in enhancing the spatial resolution of the electroencephalography (EEG) by deconvolving the low-pass spatial filtering effect of head volume conduction. In cortical imaging, an explicit biophysical model of the passive conducting properties of the head is used to deconvolve a measured scalp-potential distribution into a spatial image of potential or current source distribution over the cortical surface. Together with other approaches, the method offers promising means of probing spatially distributed brain electrical activity associated with physiological and pathophysiological processes of the brain.
