Abstract :
In this paper, a new hybrid approach to reconstruct more accurate brain functional source images from electroencephalography is proposed. The proposed approach combines extended source model and focal underdetermined system solution algorithm. Feasibility studies with realistic simulation data and the epilepsy patient´s data demonstrate that continuous, as well as focalized, brain electrical source images can be reconstructed utilizing the proposed approach
