Closely Spaced MEG Source Localization and Functional Connectivity Analysis Using a New Prewhitening Invariance of Noise Space Algorithm

Figure 2

True source locations overlaid on T1 anatomical images. Two closely spaced simulated sources (indicated by white crosses) are located at (−5, 45, 40) mm and (5, 45, 40) mm, respectively. PW-INN-based source imaging result (obtained in the condition: real MEG noise; SNR = 18; = 0) was also shown as color-coded spatial patterns, where the color denotes the imaging index from (9). The dotted red line in the sagittal view indicates the plane of  mm.
