Brain regions show significant correlations between the amplitude of low-frequency fluctuations (ALFFs) and AX (the left picture). Color bars represent t-values. L = left, R = right. The scatter plot pictures on the right indicate significant correlations between AX and mean ALFFs in the right posterior cingulate cortex. The threshold of the corrected cluster was set at p < 0.01 [single voxel p < 0.01, cluster size ≥ 40 (1084 mm3)
