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.
