Source localization of the main effects. (A) Awareness-related sources were obtained by contrasting seen and unseen trials in the 190–350 ms time-window. Three sources were observed, in the left and right lateral occipital cortices (lLO and rLO respectively), and in the right posterior infero-temporal cortex (rIT). The bar graphs depict activation strength in those three regions in each condition. Activation in those three regions was by definition significantly larger in seen trials than in unseen trials (main effect of awareness, p < 0.002). There was neither main effect of congruency (p > 0.2) nor interaction (p > 0.3) between congruency and awareness. (B) Congruency-related sources were obtained by contrasting congruent and incongruent trials in the 150–250 ms time-window. A single significant source was found in the left anterior intraparietal sulcus (aIPS). The bar graph presents aIPS activation strength in each condition. Note that the congruency effect corresponds to greater activation in incongruent trials (main effect of congruency, p < 0.01). Neither main effect of awareness (p > 0.8) nor interaction between awareness and congruency (p > 0.8) could be observed. Error bars indicate standard error of the mean.
