White Matter Tractography Analysis of the Connectivity Patterns of the Visual Cortical Areas

White matter tractography with DTI was used to examine the anatomical connectivity patterns of several cortical areas involved in visual processing situated in the occipital (Brodman?s areas 17, 18, 19), parietal (Brodman?s area 39), and temporal (Brodman?s area 37) lobes. Brodman?s areas templates were used to define regions of interest and select the corresponding white matter connectivity patterns. Probabilistic connectivity maps of each Brodman?s area were constructed by averaging the connectivity patterns for 16 subjects in a normalized coordinate space. Patterns of connectivity characteristic to each region were found. These patterns appear to be consistent across subjects.
