Clusters that exhibited the effect of speed in voxelwise analysis at whole-brain cluster-level corrected alpha of 0.05 (peak MNI coordinates, t(84) values, and cluster size [k] refers to number of 2.0 × 2.0 × 2.0 mm³ voxels). Peak coordinates are presented for completeness and potential meta-analysis; with cluster-based thresholding, it is not possible to conclude that all the reported peaks were activated [see Woo et al., 2014]
