The analysis is performed by first using motion correction, then correlating each voxel's time course with the stimulus schedule convolved with an assumed HRF shape. WebWell functional MRI is based on very similar principles but it focuses on a slightly different aspect. In its basic resting state, the brain has, obviously capillaries and arteries and veins that manage the blood supply to the brain as we have discussed extensively in one of our previous modules. irene nagy obituary
