Overview of brain activation peaks during the acoustic association control experiment. When experimental conditions were compared to control condition (provided here at , FDR corrected, fixed-effect analysis), only the contrast {acoustic localization minus acoustic control, masked (inclusive) by acoustic localization minus rest} provided results at , uncorrected, in FFX analysis. There was no significant difference in brain activation patterns between experimental conditions, even at this low threshold. Coordinates are reported in MNI space, as given by SPM2, and correspond only approximately to Talairach and Tournoux space [21]. BA: Brodmann area. () belonging to the same voxels cluster.
