Depth-dependent high resolution fMRI studies in animals and humans hold promise to reveal the input-output and feedforward-feedback connections across cortical layers. However, our understanding of the underling physiology is limited. In this work, using a cortical vascular model we simulated BOLD and VASO signal changes in human primary motor cortex.
