The severity of ScZ is correlated with the strength of mid-γ-band synchronization. Long-range γ-synchronization related to perceptual binding is reduced in ScZ. A, The fractions of significant connections of perceptual (upright-inverted) mid-γ-band (40 − 51 Hz, 325 − 425 ms) synchronization (y-axis) divided into five connection-length bins according to their normalized Euclidian distance distributions (x-axis). The proportion of significant connections in each bin was estimated separately for the 300 of most significant connections and compared to parcel-shuffled surrogates. Black and gray lines indicate the mean and 2 SD of surrogate data. B, The correlation of the GS with the disorganization PANSS and neuropsychological scores estimated for mid-γ-band GS (41 − 50 Hz, 325 − 425 ms) for the difference between upright and inverted stimuli.
