FIGURE 1

Schematic illustrations of working memory (WM) manipulation of the visual representations. The external visual information is stored in the modality-specific posterior region by the α2 rhythm. For manipulation of the stored representations, the cross-frequency phase coupling (CFPC) between θ–α2 connect the frontal (F) executive regions with parieto-occipital (PO) regions where the visual and number related information is stored. Moreover, θ–α2 interact within both F and PO regions.
