all modes (Fig. 3C). In contrast to the DMN subregions, we found a high degree of spatial overlap between the brain networks that were subject to connectivity changes. The concurrent network coupling changes included the somatomotor cortex, thalamus, frontal eye field (FEF), dorsolateral prefrontal cortex (dlPFC), anterior insula (AI), intraparietal sulcus (IPS), anterior cingulate cortex (ACC) and posterior cingulate cortex (PCC), as well as secondary associative visual (e.g., MT/V5) and auditory areas. These regions are often described as “task-positive” brain networks (23).
