The correlational analysis between the delayed recall scores on the RCFT and connectivity, in which significant differences between the BD and non-BD groups were observed, was conducted to investigate the visual memory deficit observed in the BD group concerning FC. A significant positive correlation between upper alpha band connectivity in the left prefrontal-parietal-occipital midline area and delayed recall scores on the RCFT was observed in the BD group, but no significant correlation was observed in the non-BD group. The BD group showed better performance on the delayed recall of the RCFT, as the upper alpha band connectivity in the left prefrontal-parietal-occipital midline area was stronger.
