We investigated the spatial distribution of both magnetic susceptibility and R2* across the cerebral cortex in vivo. We observed substantial variations of magnetic susceptibility and R2* across the cortical surface. Certain regions of magnetic susceptibility and R2* coincided with the boundaries of the probabilistic Brodmann atlas and other regions exhibited a heterogeneous distribution within the specific Brodmann area. In conclusion, cortical mapping of R2* and magnetic susceptibility reveals insights into tissue composition across the cerebral cortex and may be instrumental for understanding the relationship between tissue composition and functional roles of cortical gray matter.
