Results are derived from a mixed-effect analysis (11 subjects), and the clusters correspond to the voxels whose activity correlates with the listening-in-silence period (0, 1.5, 4.5, 7.5 s). The analysis is performed separately when listening to the right or the left side. x, y, and z correspond to the stereotaxic coordinates (in millimeters) in the Montreal Neurological Institute (MNI) reference brain provided with SPM2. The statistical map is thresholded at t = 3.17, which corresponds to p < 0.01. All tmax values (the maximum value of t among the voxels of the cluster) correspond to p < 0.005. Cluster size represents the number of contiguous voxels showing significant activation (2 × 2 × 2 mm voxels). Local maxima are detected within the temporal clusters. R, Right; L, left.
