Assessment of Functional Characteristics of Amnestic Mild Cognitive Impairment and Alzheimer’s Disease Using Various Methods of Resting-State FMRI Analysis

Figure 1

The mean images of each resting-state FMRI analysis approach: (a) regional homogeneity (ReHo), (b) amplitude of low-frequency fluctuation (ALFF), (c) fractional ALFF, and (d) global brain connectivity (GBC). The first row of each approach is the map for the healthy subjects, the second row of each approach is the map for the patients with aMCI, and the third row of each approach is the map for the patients with AD. The images are oriented with the anterior side placed at the top and the left side placed to the right. The red and blue colors represent positive and negative functional connectivity, respectively.
