Abstract
In this chapter we propose a solution to the Electroencephalography (EEG) inverse problem combining two techniques, which are the Sequential Monte Carlo (SMC) method for estimating the coordinates of the first two non-correlated dominative brain zones (represented by their respective current dipoles) and spatial filtering which is done by beamforming based on EEG data. Beamforming (BF) gives estimates of the respective source moments. In order to validate this novel approach for brain source localization, EEG data from dipoles with known locations and known moments are generated and artificially corrupted with noise. The noise represents the overall influence of other brain sources but they are not brain disturbances. When the power of the EEG signal due to the main brain sources is higher than the summed effect of all other secondary sources, the estimation of the localization of the leading sources is reliable and repetitive over a number of Monte Carlo runs.
