Central and peripheral vision are important for distinct aspects of everyday life. We use central vision to read and peripheral vision to get the gist of a scene. To understand how these differences are reflected in connectivity between V1 and higher-order cognitive areas, we examined the differential connectivity of V1 that represent central and peripheral vision. We used diffusion-weighted-imaging and resting-state blood-oxygen-level-dependent data to examine structural and functional connectivity. The present results demonstrate strong evidence that centrally-representing portions of V1 are more strongly functionally and structurally connected to the fronto-parietal network than are peripherally representing portions of V1. This suggests that these patterns of connections between central V1 and the fronto-parietal network are direct and support attention-demanding visual tasks. Overall, our findings contribute to understanding how the human brain processes visual information and forms a baseline for any modifications in processing that might occur with training or experience.
