Frequency-Dependent Amplitude Alterations of Resting-State Spontaneous Fluctuations in Late-Onset Depression

Figure 2

The bar graph showed the significant clusters of abnormal ALFF between LOD and NC groups with different frequency bands (slow-6: 0–0.01 Hz, slow-5: 0.01–0.027 Hz, slow-4: 0.027–0.073 Hz, slow-3: 0.073–0.167 Hz, and slow-2: 0.167–0.25 Hz). Cluster 1 mainly includes left cerebellum anterior lobe, cluster 2 includes left cerebellum posterior lobe, cluster 3 includes left middle orbitofrontal gyrus, cluster 4 mainly includes left superior occipital gyrus and left precuneus, and cluster 5 mainly includes right superior parietal gyrus and right precuneus. : the interaction of group and frequency was distributed over right superior frontal gyrus.
