Localizing True Brain Interactions from EEG and MEG Data with Subspace Methods and Modified Beamformers
Figure 3
Estimation error in RAP-MUSIC based on the real and imaginary part of the cross-spectrum. (a), (b), and (c) show the simulations of two interacting sources in 200 independent simulation cases in random locations. (d), (e), and (f) represent four sources containing two couples of interacting sources simulated in 200 independent simulation cases in random locations. The simulations were done for three different noise levels as explained in the text and as indicated in the figure.
