Autistic traits and functional EEG connectivity. (a) SRS scores. The SRS score is higher for men than women. Error bars show the SEM. (b) Scatter plot showing that age does not modulate SRS within our population. (c) Cumulative β-value distributions, showing that the entire distributions are shifted to negative values. The dotted red line is a cumulative value of 0.95. (d) Mean and SEM of β-value distributions, obtained from independent multivariate regression between SRS score and SL connectivity (including gender and age as regressors of no interest). See Table 1 for mean and standard deviations of the distributions and the P-values. All frequency bands except alpha show a bias to negative values. Matrices show thresholded β-values; a blue entry in the matrix is a negative β-value, whereas a red entry is a positive β-value. (e) Scalp plot of β-values. A link is traced between two electrodes if that connection is significant (P < 0.05, uncorrected) in all frequency bands whose β-values distribution was proved to be significantly shifted to negative values (that is, delta, theta, beta and gamma).
