Divergent topological networks in Alzheimer’s disease: a diffusion kurtosis imaging analysis

Table 3 Regions showing high betweenness centrality in DKN of control subjects

Regions	Class	Normalized betweenness, bi
Left inferior frontal gyrus, opercular part	Paralimbic	4.69
Right precuneus	Paralimbic	4.40
Left hippocampus	Paralimbic	4.26
Right inferior frontal gyrus, opercular part	Paralimbic	4.05
Left superior frontal gyrus, orbital part	Paralimbic	3.40
Left fusiform gyrus	Association	3.30
Left superior temporal gyrus	Association	2.79
Right fusiform gyrus	Association	2.67
Left thalamus	Paralimbic	2.24
Right inferior frontal gyrus, triangular part	Association	2.20

The hub regions (bi>1.5) in the GM network of the control group for the MK metric were listed in a descending order of their normalized betweenness, bi. The regions were classified as primary, association and paralimibic as described by Mesulam (1998)
