Detection and localization of epileptic seizures using ICA

An effective and simple algorithm for localization of epileptiform sources of the EEG signals within the brain has been developed here. The method includes a constrained blind source separation (CBSS) algorithm, which attempts to separate and localize the epileptifom EEG sources. The significance of the new developed algorithm is the incorporation of a proper constraint into the joint approximate diagonalization formulation. The fixed locations of the electrodes together with the normalized correlations between the estimated sources and the observed EEGs provide a sufficient geometrical information to localize the sources.
