Pair-wise correlation analyses. Group-level correlation values are between FEFs (left and right), PPC (left and right), CV, and Broca's region (left and right) for BNCs (A); CI subjects before vergence training (B); and the same CI subjects after vergence training (C). Group-level statistical comparisons reporting p-values are shown for BNC versus CI before vergence training (D), BNC versus CI after vergence training (E), and CI before versus CI after vergence training (F).
