Abstract :
In this paper, we investigate relationship between the condition number of a leadfield matrix of magnetoencephalography (MEG) and source reconstruction accuracy. We found from simulation studies that if the leadfield matrix has the higher condition number, reconstructed source distribution has the wider region and contains the more spurious sources
