cingulate, the bilateral insular and dorso-lateral prefrontal cortices. The visual network includes the retinotopic occipital cortex and temporal-occipital regions dedicated to visual processing. The sensory-motor network includes the precentral, postcentral, and medial frontal gyri, the primary sensory-motor cortices, and the supplementary motor area. Among these five networks, we detected the visual, the core and the ventral attention networks to be time-locked to the rare event presentation, and therefore to be related to the oddball task execution (Figure 2).
