Table 2. Edge weight, w(e), for edges, e, in major white matter regions (CC, corpus callosum; Cing, cingulum).
Calculated average w(e) value from the ten human datasets at 1 and 8 mm3 isotropic resolution, along with the associated coefficient of variation, cv, of the edge weight. The results are presented for the complete edge, CC long and Cing long, as well as two subdivisions (short 1 and short 2, see text) of these long edges (see Fig 6). The calculations were performed without restriction to the streamlines connecting the nodes (Without Streamline Restriction), and with the inclusion of streamlines fibers restricted (With Streamline Restriction) to originate from the connecting edge, R.
