Comparing separately the different modality, for the images the ERD AUC was significantly greater for the tools stimuli with respect to the natural stimuli in precentral (t(14) = −3.279, p = 0.005) and postcentral (t(14) = −3.597, p = 0.003) areas and almost significant in IPL (t(14) = −1.971, p = 0.069), whereas for nouns no significance was found ( Figure 3 B,C). 4.
