Abstract :
In this article, we conclude that singular value decomposition (SVD) analysis, having different frequency ranges, is useful for separating the secondary somatosensory activity from the primary somatosensory activity overlapping in time. We carried out 3D MEG measurement of somatosensory evoked field (SEF) with the electric stimulus to the right thumb.
