We present a novel intra-cortical boundary estimated
from high-resolution T1 images where cortical layer
structure is visible. The boundary between deeper
myelinated cortical layers and more superficial ones can
be used to derive two morphometric measures of local
myeloarchitecture: myelinated cortical thickness and
myelinated thickness ratio. We compare group averages of
these two contrasts to T1 and total cortical thickness,
and discuss their relevance to brain mapping and
plasticity studies.
