+ The names of the resting-state fMRI files have a prefix which indicates whether the subject is a young adult (leading digits start with "1") or an old adult (leading digts start with a "2"). The rsfMRI were preprocessed using SPM 12 and FSL and were slice-time corrected, unwarped using a field map, coregistered to individual T1-weighted images, normalized to MNI space and spatially smoothed using a 8 mm FWHM Gaussian kernel. Additional head-motion correction was performed using FSL's ICA-AROMA. Preprocessed functional data were detrended and bandpass-filtered below 0.009 Hz and above 0.08 Hz. Voxelwise regression was used to remove the effects of the mean WM signal and the mean CSF signal from the data.
