ROIs with significant difference between TCS and ICS are listed. Activations are characterized by the corresponding t and p values. Talairach coordinates (x, y, z) denotes the center of gravity of the clusters. The sides that are not listed showed no activation. The left part of the table lists those regions that had a significantly higher BOLD contrast during TCS compared with ICS. The right part of the table lists regions with the reverse effects. In case of multiple activations within the same brain region but with different coordinates of TCS and ICS, both are listed. Note that the contrast was TCS versus ICS. Therefore, t values are negative when the BOLD changes were higher during ICS than during TCS. l, Left; r, right.
