a Data analysis pipeline for implementing the Connectome Harmonic Decomposition. b Brain plots showing examples of harmonics. c Group-level searchlight classification across the harmonic space between all pairs of conditions. Performance is computed as the difference between the classification accuracy and empirical chance level (50% as the expected value). Horizontal lines indicate statistical significance. d Group-level searchlight regression across the harmonic space for both behavioral features. Performance is computed as the difference between the model \({R}^{2}\) scores and model’s performance with permuted features. Horizontal lines indicate statistical significance. Brain plots across the x-axis depict the median harmonic inside each bin.
