A Cortical surface map showing the regional significance (paired t-tests: trained vs. untrained) of semantic encoding accuracy. B A box plot showing the semantic encoding accuracy estimated for different brain regions defined in the Yeo-17 networks atlas101,113. Each dot represents an individual participant. The significance of encoding accuracy was assessed by comparing the trained model to untrained model, similar to the analysis in Fig. 2F. Asterisks denote the levels of statistical significance (two-sided paired t-test, N = 8): *, 0.01 < p < 0.05; **, 0.001 < p < 0.01; ***, p < 0.001. Exact p values are listed in Table S3. Box plots show the interquartile range (boxes), minima and maxima (whiskers), and the median (center line). C Semantic encoding accuracy (solid line) is consistently modulated over the SM-to-DMN wave cycle in six brain regions exhibiting the most significant encoding accuracy. There is no significant variation in the phase of peak encoding accuracy among these regions (p = 0.64, one way ANOVA, N = 48, 6 groups). For comparison, the average activation for each region is marked with a dashed line, which is shifted ahead of time by 6 s to account for the hemodynamic response delay. These regions are distinctly color-coded and their locations are indicated on a flattened cortical surface. Time series data are provided as the mean ± SEM for eight participants (N = 8). Source data are provided as a Source Data file.
