The activity of the lower alpha band showed stronger connectivity in the right frontal-parietal-occipital midline (t(68) = 2.40, uncorrected p < 0.01), parietal-occipital midline-left occipital (t(68) = 2.53, uncorrected p < 0.01), and right frontal-right parietal-occipital areas (t(68) = 2.59, uncorrected p < 0.01) in the BD group compared with non-BD group. On the other hand, the BD group showed weaker connectivity than that of the non-BD group in the right central-right temporal area (t(68) = −2.54, uncorrected p < 0.01).
