Previous research conducted on Myconnectome project (90 resting scan sessions of one subjects) found that systemic low frequency oscillations (sLFOs) extracted from resting-state fMRI data of big arteries to be: 1) negatively correlated with; 2) temporally leading, the fMRI data from the veins. To generalize the finding, the resting state scans from 20 randomly selected subjects of Human Connectome Project (HCP) were analyzed. The findings were validated among around 80% of the data, which also showed that cerebral circulation time between females and males are significantly different.
