A technique to identify myelination in order to map the layout of cortical areas in the human brain has been developed by researchers led by David van Essen at the Washington University School of Medicine in St. Louis. It is generally known that myelination levels are different throughout the cerebral cortex. The best way to assess it is to investigate the brain post mortem. Using the new technique of myelination mapping, it will be possible to accurately map individual cortical areas in vivo. The researchers used their method on a group of control subjects and found an excellent agreement between the spatial gradients of the myelin maps and already published anatomical and functional information about cortical areas, mostly based on post-mortem histology.
Using data from T1 and T2-weighted MRIs, the team has been able to Read more »
