Stability of resting fMRI interregional correlations analyzed in subject-native space: A one-year longitudinal study in healthy adults and premanifest Huntington's disease

► Test-retest resting fMRI scans one year apart in healthy adults and pre-HD. ► Resting BOLD correlations show good longitudinal stability over one year. ► Analysis in native space to avoid confounds from misregistration to standard space. ► Pre-HD has only modest effects on resting BOLD correlations.
