Electroencephalogram source localization (ESL) attempts to detect the sources of the brain activities by electroencephalography (EEG). ESL has been an important research area for both clinical and basic brain research such as neurology, psychiatry, and psychopharmacology since the 1950s. Current dipoles are used to model the electrical activities in the ESL. These dipoles can be determined by the artificial neural network (ANN) model instead of numerical methods. A genetic algorithm (GA) can be used to reinforce and optimize the architecture of the ANN model and increase the localization accuracy. The purpose of this study is to detect the sources of brain activities using a GA-based ANN model by reviewing recent patents and literature. EEG data was simulated and three concentric spheres (scalp, skull, brain) were used for modeling the head as a volume conductor. The preliminary results indicated that the localization accuracy was 0.01 mm. According to preliminary results, the proposed GA-based ANN model can be used to obtain the sources of equivalent current dipoles.
