Synopsis

Keywords: Brain Connectivity, Arterial spin labellingWe evaluated the relationship between attention levels and brain global efficiencies. This relationship was compared with brain global efficiencies measured with dynamic ASL (dASL) and with multi-echo (ME) BOLD fMRI. We found significantly greater correlation between attention levels (reflected by P3 properties when performing an attention task) and brain global efficiencies based on rsFC using dASL than those using ME BOLD fMRI, indicating that dASL can offer more accurate global neural signal fluctuations.
