Automatic volumetric segmentation of human retinotopic cortex

€Automatic
€No cortical surface required
€Directly supplies volumes for VOI analysis

Our specific version developed by Dumoulin, requires no cortical surface reconstruction and yields a volume of interest analysis directly. Slide with three vectors, based on rate of change: polar angle, eccentricity and aMRI.  VOI involves collapsing the voxels in each visual area, of each subject, and averaging across subjects.
