By increasing the acquisition frequency of resting-state fMRI data from 0.5Hz to 2Hz, we found that the resting-state default mode network still exists in the higher frequency band of the BOLD signal. Including the higher frequency band functional connectivity can increase the individual resting-state functional connectivity repeatability within and between sessions.
