IR-MRI provides enhanced image intensity in the human
cortex that enables its subdivision to laminar shaped
clusters. These clusters reflect cytoarchitectonic
organization in the cortex, which could be further used
for visualizing and quantifying changes due to brain
impairment. In this study, IR-MRI analysis framework was
employed on congenitally blind and sighted control
subjects focusing on the visual cortices (V1 and V2). We
explored the clusters composition on each region, aiming
to expose microstructural differences originating
probably from lack of input to the visual cortex as
occurred in blindness.
