s-core decomposition of the connectome. a shows the results of the s-core decomposition (see Materials and Methods) of the NOS-weighted brain network, marking a high core-level of rich-club regions, including bilateral superior frontal cortex, precentral gyri, thalamus, hippocampus, and putamen. b shows s-core decomposition of cortical regions (i.e., excluding all subcortical regions from the analysis), showing a high core level of bilateral precuneus, superior frontal and superior parietal regions, overlapping previous findings of Hagmann et al. (2008). c and d show a network perspective of a and b.
