a Vector-of-ROIs action-effector index (right) and grasp index (left). Statistical significance was assessed using two-sided one-sample t-tests, and color-coded lines at the top of each plot indicate spheres along the vectors where each index reached significance, Bonferroni corrected for the number of spheres (n = 34; p = 0.0014). The shaded area around the line indicates ± 1 SEM across participants (n = 18). PHC Parahippocampal Cortex, mFG medial Fusiform Gyrus, lFG lateral Fusiform Gyrus, OTS Occipitotemporal Sulcus, aITG anterior Inferior Temporal Gyrus, pITG posterior Inferior Temporal Gyrus, LOS Lateral Occipital Sulcus, TOS Transverse Occipital Sulcus. b Action-effector index (top) and grasp index (bottom) for the three artificial networks tested. Statistical significance was assessed using permutation tests (10,000 random shuffles of category labels), and color-coded lines at the top of each plot indicate layers where each index reached significance (p < 0.001). In all panels, red = face indices; orange = body indices; yellow = hand indices. Source data are provided as a Source Data file.
