Activation evoked by brushing on the palm and back of the left hand. Regions responding to brush > rest in both scans. Peak defined as the voxel in the cluster with the highest Z score. Clusters are displayed above a statistical threshold of Z > 3, whole-brain corrected for multiple comparisons (p < 0.01; N = 17). x, y and z MNI coordinates correspond to the left–right, anterior–posterior and inferior–superior axes, respectively.
