Global tractography, sketch of diffusion tensor images, DTI, of the default mode network, DMN: is a set of areas active at rest. The upper C-shaped arch (green-yellow-purple) with widespread projection bundles (green-purple) is the cingulate cortex. The cingulum bundle radiates far-reaching antero-posterior connectivity from medial prefrontal lobe to the precuneus and other areas of the brain, e.g., frontal, parietal. The fornix, a lower and smaller C-Shaped arch is a major output projection tract of the hippocampus.
