The human brain is a complex dynamic system made up of billions of nerve cells called neurons.  Clusters of neurons in specific brain areas are continuously being activated or deactivated to perform specific functions.  This ongoing activity can be recorded in a non-invasive manner through an electroencephalogram (EEG) which captures the electrical activity in the form of graphs.  This data, read from various electrodes placed on the scalp, can then be processed to localize the brain activity.  This is done through source localization techniques which are comprised of a forward and an inverse problem.  In the forward problem simulated sources are placed within the brain model and the scalp potentials are estimated taking into account the brain physical characteristics.  In the inverse problem we use the information obtained through the forward problem to estimate the location, magnitude and orientation of the sources giving rise to the recorded EEG data.  This is a very complex problem as there exist various solutions yielding the same brain activity.

The department has been working on this problem for several years and it has been one of our main contributions in the BIOPATTERN Network of Excellence partly funded by the EU’s Sixth Framework IST Programme. Within BIOPATTERN, source localization for a 3-layer spherical head model was applied to the analysis of brain activity of subjects suffering from Alzheimer’s disease as compared to normal subjects. Detailed reviews, Monte Carlo studies and biomarker studies of source localization have been performed resulting in a number of publications.
