From: Testing covariance models for MEG source reconstruction of hippocampal activity
Spatial distributions of the reconstructed source power for unilateral, dual-uncorrelated and dual-correlated simulation scenarios (SNR = − 10 dB). When sources were uncorrelated, EBB and cEBB inversion models gave similar results, whereas in the presence of correlated sources, EBB power fell back onto a topography akin to IID. Although qualitatively cEBB reconstructs all three scenarios it is only objectively the best model (see model evidence scores in Fig. 1) for the dual-correlated sources. Results have been transformed into MNI space for visualisation purposes.
