From: Stability of graph theoretical measures in structural brain networks in Alzheimer’s disease
The average binary adjacency matrices of 1000 connectivity matrices binarized at a threshold corresponding to 15% network density when randomly subsampling 100 subjects (left) and 200 subjects (right) respectively. In each subfigure, the top row are the results from the control group (CTR) and the bottom row from Alzheimer’s disease group (AD). These connectivity matrices were constructed from different combinations of anatomical atlas and cortical measures (a–d). Each matrix element represents to the probability of two nodes being connected, ranging from 0–1 as shown by the colorbar.
