Fig. 6: Strength of the RBP difference and timing of crossover between externally and internally oriented attention.

a The strength of neural representation during attention switching. The strength of the RBP difference (in dB) between external-to-internal and internal-to-external attention switching was computed across all significant channels in a given frequency band as a log-transformed mean across the entire time interval from −2.3 s to 2.3 s. The width of the violin-like plots represent the data distribution across channels (colored dots), mean is denoted by red line, median by white circle and gray boxes represent the interquartile range. In both networks, the largest strength of difference was observed in the power of the low-frequency bands (<30 Hz), but also in the HGB (52–120 Hz). A small strength of the RBP difference was observed in the low-gamma band (LGB, 31–48 Hz). The insets above error bars represent significance of difference (black: P < 0.001; white: P > 0.001, FDR corrected) between the different bands assessed by a Wilcoxon rank sum test of the trial-averaged channel RBP activities. b The distribution of crossover points of neural activity between external-to-internal and internal-to-external attention switching for the DAN (green) and the DMN (cyan). Same notation for the violin-like plots as in a, each dot represents a single-channel cross-over time of RBP between the task conditions. The switching occurred significantly faster (P < 0.001, FDR corrected) in the DAN than in the DMN, but only in the HGB.
