Signal and noise correlations. (A) Signal correlation matrix in the gamma band (80–95 Hz) for all V1–V4 site pairs. (B) Distribution of signal correlation values for all interareal site pairs as a function of frequency. (C) Noise correlation matrix in the same band as in A. (D) Distribution of noise correlation values as a function of frequency. (E) Correlation of interareal signal and noise correlation matrices (A and C) across frequencies. Frequency–frequency plane threshold P < 0.05 corrected for multiple comparisons. Significance threshold is denoted on color bar by red line and value.
