Figure 6. Reliable Rank Ordering for Anatomical Parcellation.

Figure 6

Given that each participant had 3 scans, standardized Amplitude of Low Frequency Fluctuations (ALFF) and fractional ALFF (fALFF) measures (i.e., Z-scores) were obtained for each parcellation region separately for each scan. The parcellation regions were then ranked based upon their standardized ALFF and fALFF. For each scan, the mean rank for a parcellation region was obtained by averaging all individual ranks for the region. (A) The reliability of mean ranks. (B) The reliability of subject-level ranks. Overall these panels illustrate the consistency of ALFF- and fALFF-based rank orderings for the parcellation regions over the short- and long-term (intra-session and inter-session, respectively).
