MD indirect tracts (MDi) in a axial, b coronal axial, c sagittal views, and d comparison of 3D rendered views of Hb (pink), and ANT nuclei (yellow) overlaid on the MNI brain template (threshold: 0.2–0.5). Note the almost exclusive and left dominant connection between the hippocampus via fornix and ANT nuclei to the mediofrontal cortices.
