Abstract	Estimation of the electrical cartography on the scalp surface requires a solution to the EEG inverse problem, but, there is no unique solution to this problem. In this paper we present Standardized LOw Resolution brain Electromagnetic TomogrAphy ldquosLORETArdquo, the FOCal Underdetermined System Solver ldquoFOCUSSrdquo, and the new combination solution ldquosLORETA-FOCUSSrdquo methods. The purpose of this paper is to present the technical details of these methods, and give some comparison between them. The results demonstrate that using each method, we obtain different results given the reconstruction in 3D of the cerebral activity in the brain from where we evaluate the efficiency of the sLORETA-FOCUSS method to reconstruct a three dimensional source distribution with smaller localization and a minimum of localization error.
