Like the power analyses above, we first assessed the effect of State (S-RS vs M-RS) on α-frequency connectivity (collapsed across the groups). We observed reduced bidirectional α connectivity from the S-RS to the M-RS within the DMN: PCC→mPFC (M-RS minus S-RS; t = −3.49, p = 0.001, FDR p < 0.05, d = 0.85) and mPFC→PCC (t = −3.14, p = 0.003, FDR p < 0.05, d = 0.76), suggesting disrupted DMN connectivity in general by salient visual input (at M-RS).
