FIG. 1.

The framework utilizes a set of GM nodal regions and a FOD image to determine three features related to the structural connectivity of the subject: (1) a structural connectivity matrix (only left hemisphere is shown) describing the number of connections between each pair of nodes, (2) the nCD, describing the proportion of connections terminating in each node, and (3) a connection density image describing the density of connections as they traverse the WM. GM, gray matter; FOD, fiber orientation distribution; nCD, nodal connection distribution; WM, white matter.
