What's the relationship between the blood flow and energy use? I know fMRI uses BOLD which then has an IIRC ~6s expected pattern that you apply as a convolution on the data, as it's looking at the oxygenation of the blood. Here it's energy use -> vasodilation -> change in blood flow - what's the relationship like between those?
