The reconstruction of the structural brain networks. a First, a whole-brain constrained spherical deconvolution-based tractography was performed for all subjects. b Then, Automated Anatomical Labeling atlas was used to parcellate the brain into 90 regions. c These regions become the nodes in the brain networks. The size and color of the nodes correspond to the volume of the region in the Automated Anatomical Labeling atlas. d Finally, a link was formed in the brain network, if there was at least one tract between two nodes. The thickness of the links corresponds to the density-weight of the connection, i.e., the number of fibers divided by the mean volume of the two nodes. All of the above steps were performed in the individual space of each subject
