 This page describes the definition of the regions of interest for five fiber bundles: the Internal Capsule, the Uncinate Fasciculus, the Fornix, the Arcuate Fasciculus and the Cingulum Bundle.[[Image:ColorPalette.png|thumb|right|300px|Color Palette]]
 Seed points were defined using a two ROIs approach. Each ROI was drawn on FA and color by orientation maps according to the criteria defined below:
