Functional connectivity of visual regions predicts performance. Individual differences in pretraining resting-state functional connectivity predicted task fitness. Colored regions projected onto the lateral and medial cortical surfaces approximate visual (yellow, dorsal; green, ventral) and control (dark blue, prefrontal cortex; light blue, insula) regions. Task fitness was positively correlated with pretraining functional connectivity (red arrows) between heterotopic (i.e., dorsal to ventral within and across hemispheres) but not homotopic (ventral to ventral and dorsal to dorsal across hemispheres) or local (within visual quadrant) visual regions. Conversely, task fitness was negatively correlated with pretraining functional connectivity (blue arrow) between visual regions and both prefrontal and insular areas involved in cognitive control.
