Before revision:  A common approach to modeling dynamic connectivity in resting-state whole-brain  fMRI is to compute (across moving temporal windows) the Pearson-correlation between anatomical regions derived from predefined brain parcellation.
After revision: Background: Recent studies have indicated that functional connectivity is dynamic even during rest. A common approach to modeling dynamic connectivity in resting-state whole-brain fMRI is to compute (across moving temporal windows) the Pearson-correlation between anatomical regions derived from predefined brain parcellation.
