In this study, we explored the vascular effect of a fed-caffeinated condition versus a fasted-uncaffeinated condition in resting-state fMRI dataset from the Myconnectome project. We extracted the low frequency oscillation signal from the superior sagittal sinus (SSS) as a vascular seed to evaluate the propagation of these signals through the brain in these two conditions.
