“…A non-invasive method for CBV imaging is vascular-space-occupancy (VASO) (Lu et al, 2003), which takes advantage of the difference in blood and tissue 𝑇𝑇 1 to image the tissue signal while the blood signal is nulled (Huber et al, 2014b;Lu et al, 2003). Since the development of this contrast and its translation to 7 Tesla (T), several studies in animals and humans have been conducted in the areas of method development (Beckett et al, 2019;Chai et al, 2019;Huber et al, 2015;Huber et al, 2016;Yu et al, 2014), analysis strategies (Huber et al, 2021;Polimeni et al, 2018), and applications to cognitive neuroscience (Finn et al, 2019;Huber et al, 2014a;Huber et al, 2017a;Kashyap et al, 2018;Oliveira et al, 2021b;Van Kerkoerle et al, 2017). However, to interpret the experimental results and account for both neural and vascular contributions to the fMRI signal, detailed models are required (Buxton et al, 2004).…”
