The table details the Brodmann area, Talairach co-ordinates (x, y, z) of the peak of the BOLD signal, the maximum t-score and the number of voxels in each region. The italicized numbers denote a significant negative BOLD signal; all other regions show significant positive BOLD signals compared to the baseline.
