Local structure–function coupling. Spatial distribution of the cross-modal differences in structure–function coupling between (a) EEG and HbO, and (b) EEG and HbR, in RS and task conditions, represented as z-values. A higher absolute z-value indicates a more significant difference between the two groups, with dot size indicating the absolute z-value. A positive z-value indicates higher coupling for fNIRS, while a negative z-value indicates higher coupling for EEG. Only significant regions of interest (ROIs) are shown (p < 0.05), FDR corrected.
