Enhancement in temporal correlation between frontal alpha EEG asymmetry (FAA) and BOLD activity during the rtfMRI-EEG-nf training. Statistical maps of the FAA-based PPI interaction effect for the Happy Memories vs Count condition contrast (H vs C) are shown for the experimental group (EG). The maps are voxel-wise FDR corrected and projected onto the standard TT_N27 anatomical template, with 3 mm separation between axial slices. The number adjacent to each slice indicates the z coordinate in mm. The left hemisphere (L) is to the reader’s right. Peak t-statistics values for the FAA-based PPI interaction effect and the corresponding locations are specified in Table 2.
