The ICA-based analysis of fMRI data provided a number of independent spatio-temporal patterns. We identified five fMRI networks, which were consistently found across all subjects (Figure 2). Their spatial maps were essentially coextensive with the dorsal attention, the ventral attention, the core, the visual and the sensory-motor networks, as previously defined in neuroimaging studies on active and passive behavioral tasks [Corbetta and Shulman, 2002; Dosenbach et al., 2006; Fox et al., 2006; Nir et al., 2006]. The ventral attention network is typically related to target detection processes and mainly includes the right temporo-parietal junction, inferior and middle frontal gyrus, and anterior cingulate. The dorsal attention network is associated with orienting of attention, and primarily includes the intraparietal sulcus, the frontal eye field (FEF), and the middle frontal gyrus. The core network is dedicated to task control and includes the anterior 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
