a Average percentage of voxels in each ROI that show significant improvement over baseline in prediction score at the group level (Pearson’s r, TFCE 10 k permutation, p < 0.05, n = 19 subjects for each individual point). Baseline brain prediction is obtained by feeding alternative sequences of images into the model, where no learning happens. FC shows the highest percentage of significant voxels. Each point shows the individual ROI within group. The center line shows the average of that ROI group, error bars show the 95% CI across individual ROIs. b Higher dorsal stream median information strength is associated with lower learning success. The center line shows the estimated parameter value, error bars show 95% CI of parameter estimate. *: significant parameter (logit link Binomial family GEE parameter t-test, p < 0.05, FDR-corrected). c Higher FC median information strength is associated with higher learning reliability. The center line shows the estimated parameter value, error bars show 95% CI of the parameter estimate. *: significant parameter (log link gamma family GEE, parameter t-test, p < 0.05, FDR-corrected). d Information strength connectivity pattern associated with successful perceptual learning effect (Spearman’s rho parameter estimate using GEE, t-test p < 0.05, FDR-corrected).
