Imaging of electroencephalographic potentials using distributed source models in psychiatric research
2005
Abstract
The article provides a review of methods of corical mapping of brain electric activity. The first part of the article explains the neurophysiological background of functional localization using source dipole modelling of EEG potentials, and some methodological problems of source localization.
Three steps in source localization (construction of head models, solving of the forward and inverse problem) are described. Finally, results obtained with low resolution electromagnetic tomography (LORETA) method in psychiatric research are reviewed
