Abstract
⺠Map individual vessel fMRI responses in deep cortical layers. ⺠Penetrating macro vessels dominate the deep-layer peak BOLD responses. ⺠Decouple the time-dependent macro/micro-vascular contribution to BOLD signals. ⺠BOLD signal at 0.8 s after stimulation is less contributed by macrovasculature.
