Fig. 2From: Exploring morphological similarity and randomness in Alzheimer’s disease using adjacent grey matter voxel-based structural analysisBrain regions with significant difference in regional structural similarity. We first generated the group average probability of structural pattern indices. Next, we calculated the distances (dissimilarities) for the same region between the CN and AD groups. The nodes represent the brain regions with significant dissimilarity, and the colors illustrate the IBS distances. AD: Alzheimer’s disease; CN: cognitively normal older adults; IBS: information-based similarity; ACG: anterior cingulate and paracingulate gyri; HIP: hippocampus; OLF: olfactory cortex; PCG: posterior cingulate gyrusBack to article page
