Correlation Matrix Map

Correlation matrix between the time series of the regions detected as part of a large-scale network. The matrix has been organized to reveal the organization of the regions into sub-networks, ie the matrix has a block-structure, each block corresponding to a group of regions whose temporal activities are highly correlated (bright red diagonal square), and smally or negatively correlated with the activity of other regions (dark or blue off-diagonal rectangles). The diagonal square corresponding to the first sub-network is outlined in light grey.
