Summarized are the sLORETA results of significant differences in brain electrical activity in different comparisons and for different frequency bands. Coordinates are defined in the standard stereotaxic space of Talairach and correspond to the observed activation maxima. The row “Cluster including” describes the extent of the activated brain region. The results were considered significant in case of p < 0.05, corrected for multiple comparisons.
