MNI coordinates of peaks of relative activation within regions from the body-only contrasts demonstrating repetition suppression for novel, compared to repeated postural configurations, collapsed across contorted and ordinary postures, and novel and repeated viewpoints (a); repetition suppression for novel compared to repeated viewpoints, collapsed across contorted and ordinary postures, and novel and repeated postural configurations (b); and the interactions between repetition suppression for postural configuration and viewing angle (c and d)
