Fig. 2
SPM analysis of the four main conditions. (A) Manipulation right and left versus baseline and (B) observation of manipulation by the right and left hand versus baseline at significance level p of delineated clusters < 0.05 (corrected for FWE), and extension threshold 20 voxels. Activations are integrated in axial slices of mean T1-images related to the study cohort. Ventral PMC/posterior Broca area BA 44, a node of the classical mirror network, appears preferentially in the right hemisphere during motor execution of both hands in the transversal slice of MNI z-level 30 (A) but not during action observation of hands (B). For list of activation areas, including specific T-values of the involved brain areas, see Supplementary Material, Tables ST4 and ST5.
