aBoth auditory stimuli and motor output were subtracted out of the brain activity, but activity in the motor cortices and cerebellum remains. MNI coordinates (p < 0.05 FDR-corrected, minimum spatial extent threshold of 5 voxels) are shown as well as the Z score and spatial extent in voxels (see also Fig. 4B).
*Significant after clusterwise FWE correction (p < 0.05).
