An fMRI acquisition of 10 Hz sampling rate was achieved
by using MR-Encephalography with a three-dimensional
single-shot stack of spirals trajectory which provides
the possibility to inspect brain network structures in
spatial, temporal and frequency domains. In this study
we used ICA and partial correlation analysis to
construct the brain networks and found hub regions and
compare network characteristics in the resting-state
functional structure at frequencies as high as 5 Hz.
