Vascular origins of low-frequency oscillations in the cerebrospinal fluid signal in resting-state fMRI: Interpretation using photoplethysmography
A. Attarpour, J. Ward, J. J. Chen
This study investigates the relationship between low-frequency cerebrospinal fluid (CSF) oscillations and vascular signals using resting-state fMRI and photoplethysmography, finding that vascular contributions vary across CSF regions and that PIR is more strongly associated with CSF signals than PPG.
