Local Immediate Versus Long-Range Delayed Changes in Functional Connectivity Following rTMS on the Visual Attention Network

• Offline inhibitory rTMS over the left intraparietal sulcus has a local, immediate and brief impact on the network integrity to functionally connected cortical regions in the dorsal attention network• Those individuals with more disruptions in local functional connectivity are most impaired on sustained visual attention tasks, which dovetails with the hypothesized role of interhemispheric balance for bilateral visual sustained attention• rTMS over left intraparietal sulcus creates remote and delayed increases in interregional functional connectivity in distal brain sites, which may have implications for models of compensatory mechanisms that may be stabilized in chronic stroke
