For all significant contrasts calculated on the cortical sources of the SPP and N400 time intervals, the table displays the MNI coordinates of the voxel with highest t value, its t value, the number of significant voxels per each significant cluster, P values, and the Brodmann area labels where the “peak voxel” was found, along with a description of the cortical area where the active cluster was located.
