Significant differences resulting from the interaction contrasts Intensity (Painful>Non-painful)>Unpleasantness (Painful>Non-painful) and vice versa.

Notes: Voxel threshold P = 0.001 (uncorrected), cluster size threshold k = 5. * P = 0.005, k = 5; stereotactic coordinates and t-values are provided for the local voxel maximum of the respective cluster. x = sub-peaks of a cluster, L = left hemisphere, R = right hemisphere, M = medial activation, k = number of activated voxels in cluster; areas (in brackets, e.g. OP4) determined based upon cytoarchitectonic maps provided in the Anatomy Toolbox.
