Changes in magnitude of ALFF calculated at different frequency bands.

<p>The mean zALFF maps were calculated from 10 subjects using RS1, RS2 and RS3 datasets at the frequency bands “slow 2 (0.198–0.25 Hz)” (A), “slow 3 (0.073–0.198 Hz)” (B), “slow 4 (0.027–0.073 Hz)” (C) and “slow 5 (0.01–0.027 Hz). No threshold was set to these maps. The negative zALFF is depicted by a blue-to-green color, which represents the brain regions with lower ALFF values than the global mean ALFF (i.e., the whole-brain averaged ALFF value); the positive zALFF is depicted by a red-to-yellow color, representing regions with higher ALFFs than the global mean. The ROI-wise mean zALFF values were also plotted against different frequency bands (E) for the 10 ROIs.
