High resolution 7T MRI allows to investigate the functional and structural organization of human cerebral cortex at an unprecedented level of detail, visualizing myelination patterns over the cortical surface and identifying a large number of cortical areas. In this study we hypothesize that myelin content co-varies with loss of visual input. We used a modified T1-w MPRAGE to enhance myelin visualization within gray matter and acquired data from patients with hemianopsia, a visual field defect consisting of an absolute scotoma limited to a single hemifield, and evaluate whether the clinical symptoms are reflected in gray matter myelination in the occipital cortex.
