Results of the standardized low-resolution brain electrotomography (sLORETA) source localization analysis in the ‘passive’ and ‘active’ pure tone oddball paradigm. Images have been obtained after statistical non-parametric mapping (SnPM) and co-registration to the stereotaxic Talairach space based on the Co-Planar Stereotaxic Atlas of the Human Brain [72] and the probabilistic MNI-152 template [70]. Activated voxels are indicated by yellowish and reddish colors [after correction for multiple comparisons (p < 0.01 and p < 0.05, respectively)]. a In the averaged time windows of the ‘unattended’ MMN component (80–123 ms), the peak of highest cortical activity has been found in the right LG (BAs 17/18/19) and right STG (BAs 13/22/39/42). b In the averaged time windows of the ‘attended’ MMN component (83–95 ms), the peak of highest cortical activity has been found in the right IPL (BAs 7/39/40). c In the averaged time windows of the ‘unattended’ P3 component (269–322 ms), the peak of highest cortical activity has been found in both insulae bilaterally (BA 13) and the right LG (BA 18). d In the averaged time windows of the ‘attended’ P3 component (253–351 ms), the peak of highest cortical activity has been found in the precuneus/SPL bilaterally (BAs 7/19/23/21).
