WebFeb 12, 2024 · Theta-band coherence was estimated by the average coherence across±3 frequency points around the peak of the single-dyad’s coherence spectrum in the range of 3–8 Hz in the cooperation task. We found that theta-band coherence was significantly negatively correlated with balance index (Spearman’s rho = -0.537, p = 0.016, Fig. 4c). WebDifferences in coherence between groups were analyzed using analysis of variance. Results Theta coherence between the F7 and T3 electrodes was lower in the SSD group than the MDD and HC groups (F(2,42) = 6.67, p = .0030). Theta coherence between the T5 and P3 electrodes was lower in the SSD and MDD groups than the HC group (F(2,42) = 5.65, p ...
