Dominant modes of connectivity in the three cognitive regimes. Depicted are the effective connectivity patterns reconstructed from the dominant singular vectors and thresholded within a matrix at an arbitrary level based on the empirical distribution. Solid lines indicate positively valued connections while dashed lines indicate negatively valued connections. Abbreviations: S/M, primary sensory-motor cortex; PM, premotor cortex; SMA, supplementary motor area; L, left hemisphere.
