Table 2.

Connectivity matrix can be subdivided into components defined by shortest possible fiber path connecting voxel pairs. The size, mean DTI and Resting connectivity and the mean correlation between resting and DTI connectivity are presented. Clearly inclusion of voxel pairs that can only be connected by a multi-fiber path is extending the connectivity measures to obtained covareage of substantial part of whole connectivity space. Even the 8th component composed of weakly connected voxel pairs that require 8 consecutive fibers to connect them still shows substantial correlation with resting correlation connectivity estimate.
