In this work, we investigated the oscillations on the flow cerebrospinal fluid in the human brain using ultra-high field magnetic resonance imaging with a homogeneous head coil. Acquisition and analysis of images from 5 human volunteers results in identification of different frequency bands around 0.3, 0.8, 1.2, 2.3 and 3.4Hz. The analysis of the frequency spectrum and spatial localization of the signal yield results that could be correlated with physiological processes and CSF clearances.
