Attention and speech-processing related functional brain networks activated in a multi-speaker environment - Fig 5

FC networks significantly affected by ATTENTION: stronger for focused than for divided attention (Focused Attention Specific Networks: EEG delta, low alpha, and beta bands; left: A) and stronger for divided than for focused attention (Divided Attention Specific Networks: EEG delta and beta bands; right: B). The left column of panels A) and B), separately shows the regional distribution of the functional connections (color scale right from each panel). 100% refers to the sum of the connections comprising the significant network. The relative distributions of the connections are calculated for frontal, cingular, temporal and parietal cortices pooling the two hemispheres’ data. For the sake of simplicity, the values are plotted only above the diagonal. The right column of panels A) and B), separately shows a visualization of the significant networks on a plot of the cortical surface (top, left, and right view). Dots represent the spatial locations of the EEG sources reconstructed for cortical regions (nodes) in MNI space. The colors of the nodes indicate the cortical lobe: red–frontal, yellow–cingular, green–temporal, blue–parietal cortex. The size of the node represents the degree (number of connections within the network) of each node (see S5 Table).
