The dynamic properties of resting-state functional connectivity (FC) provide rich information for studying brain-behavior relationships
.
Dynamic mode decomposition (dynamic modes, DMD) is a method used to characterize the dynamic characteristics of FC

To validate the method, the study tested whether each of the 59 behavioral measures could be predicted by multivariate pattern analysis of the Gram matrix using subjects' resting-state fMRI (rs- fMRI) data were calculated to create a specific DM

In this study, DMD successfully predicts behavior and outperforms a traditional data decomposition method for extracting spatial activity patterns, spatiotemporal independent component analysis
.
In a permutation test, most behavioral measures were related to cognition
This study successfully established a method for predicting individual differences in behavioral measures of DM inherent to rs-fMRI activity
.
show that DMD is superior to spatiotemporal ICA
This study successfully established a method for predicting individual differences in behavioral measures of DM inherent to rs-fMRI activity
The findings highlight the superiority of DMD in data decomposition methods for extracting spatiotemporal features from rs-fMRI data
DMD can efficiently extract spatiotemporal features from rs-fMRI data
