Imaging cortical myeloarchitechture in-vivo is valuable
for study brain anatomy and functional organization.
With improved spatial resolution and sensitivity, T1
imaging may allow precise mapping of cortical
myelination distribution and reveal subtle abnormalities
underlying developmental brain disorders. We report here
a high resolution imaging protocol optimized for
anesthetized rhesus monkey studies. The sensitivity and
resolution provided by our implementation afford us to
observe the V2 CO stripes, a known architectonic
features that have been visible in histology but have
not been observed previously using MRI in a living
brain.
