Figure 6. Signal decomposition into anatomy.

Figure 6

BOLD signals are decomposed into aligned and liberal signal components. Left of equation: a schematic BOLD signal on a simple anatomical network. Here, two signals are stronger in the high direction than the low direction. Right of equation: the signals across the network are decomposed into an aligned and liberal component. The original signals can be reconstructed from a basis set including a weighted part of the signal that is aligned with the anatomical network and another part that is liberal with respect to the anatomical network.
