Spearman’s correlations between the mean CC, in the seven EEG frequency bands of interest (delta: 2–4 Hz; theta: 4–8 Hz; alpha-1: 8–10.5 Hz; alpha-2: 10.5–13 Hz; beta-1: 13–20 Hz; beta-2: 20–30 Hz; gamma: 30–40 Hz) and the neuropsychological scores (MoCA and social cognition measures). Correlation coefficients and corresponding uncorrected p-values are reported. Significant correlations after FDR correction are reported in bold. [*p < 0.05; **p < 0.01]
