Alpha rhythm is correlated with cortical myelination (T1w/T2w) (VIDEO)

Caption

This video illustrates the lifespan trajectory of the alpha process and its relationship with cortical myelination (T1w/T2w). Both the predicted myelination measure (derived from conduction efficiency, 1/τ²) and the cortical alpha source maps are estimated using the ξ Xi–αNET generative model applied to resting-state EEG across the lifespan. The left panel displays model-derived cortical maps highlighting posterior alpha dominance, while the right panel shows the age-dependent association between predicted myelination  and empirical cortical myelin indices. The visualization demonstrates structural–functional coupling between alpha rhythm dynamics and cortical myelination from childhood to old age.
