Figure 4

Group analysis on the Fourier spectral decomposition of the correlation between areas 3b and 1 in resting state BOLD signals and LFPs in seven frequency bands. (A) Normalized percentage of spectral analysis of sliding window coherence, comparing LFP delta (black) and gamma high (red) bands. (B–F) Cumulative percentage of variation in correlations from different frequency bands; (B) over 0.02 Hz; (C) between 0.01 and 0.02 Hz; (D) between 0.005 and 0.01 Hz; (E) between 0.0025 and 0.005 Hz; (F) less than 0.0025 Hz. *Wilcoxon signed-rank test at p < 0.05. A total of 9 runs from three monkeys were analyzed for BOLD and LFP measurements, respectively. Error bars indicate standard deviations.
