Mapping vascular network architecture in primate brain using ferumoxytol-weighted laminar MRI.

⮚ Cortical layer vascular mapping using ferumoxytol-weighted R2* MRI⮚ Vascular volume is high in primary sensory areas and low in association areas⮚ Correlation between R2* and vascular volume with neuron and receptor densities⮚ Vascularization co-varies with densities of specific interneuron types.
