Figure 2From: Separation of phase-locked sources in pseudo-real MEG data The three sources estimated by IPA (left), PLFs between them (middle), and the gain matrix W T A(right). Black squares represent negative values of the gain matrix, while white squares represent positive values. Since the gain matrix is very close to a permutated diagonal matrix, we can conclude that IPA successfully recovered the sources, up to permutation, scaling, and sign change.Back to article page
