  1. (Abbreviations: k = cluster size, Z = Z-value; activation significant at p < 0.001 uncorrected, p < 0.05 FWE corrected on cluster level)
  2. Coordinates are reported as given by SPM8 (MNI space) and correspond only approximately to Talairach and Tournoux space (Talairach and Tournoux, 1988, Brett et al., 2001). The label denotes the location of the maximum. Abbrevations: Parietal_Sup - superior parietal lobe, Caudate - caudate nucleus, Frontal_Mid - middle frontal gyrus, Frontal_Sup - superior frontal gyrus, Occipital_Inf - inferior occipital gyrus, Supp_Motor_Area - supplementary motor area, Precentral - precentral gyrus, Lingual - lingual gyrus, Occipital_Mid - middle occipital gyrus, Angular - angular gyrus, Frontal_Inf_Orb - inferior orbital frontal gyrus, Temporal_Inf - inferior temporal gyrus, Cingulum - cingulate gyrus, * this activation is part of a bigger cluster
