Group activations were analyzed using a voxel-wise significance level of p < 0.05, corrected for multiple comparisons with a 3D extension of the cluster-correction method. Significant activation foci are shown in Talairach coordinates (37). Cluster sizes for each contrast: head right > rest = 102; head left > rest = 89. Contrasts that did not reach statistical significance are not shown.
