(Abbreviations: k = cluster size, Z = Z-value; activation significant at p < 0.001 uncorrected, p < 0.05 FWE corrected on cluster level)
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: Calcarine - calcarine gyrus, Frontal_Inf_Oper - inferior frontal gyrus, Temporal_Mid - middle temporal gyrus, Frontal_Inf_Orb - inferior orbital frontal gyrus, Angular - angular gyrus, Cingulum_Post - posterior cingulum, Frontal_Sup - superior frontal gyrus
