Fig. 6. Univariate analyses results.

Time-frequency representations of BC (A) and XY (B) encoding, covering the frequencies from 3 to 30 Hz, were transformed into dB representations for visualization purposes. A cluster-based permutation analysis was used to estimate the power differences between BC and XY encoding. The significant clusters were marked in red (for BC > XY) and black (for BC < XY) edges (C). The topographies of the significant clusters of differences between BC and XY are plotted in (D).
