Figure 4.

Results of diffusion tensor tractography of the fornix (right – red, left – yellow) of patients with mild traumatic brain injury.

Abundant unusual neural tracts (green arrows) are observed. These unusual neural tracts can be classified as follows: (1) the neural branch originating from the fornical column to the ipsilateral medial temporal lobe, (2) the neural branch originating from the fornical column to the contralateral medial temporal lobe via the splenium of the corpus callosum and (3) the neural branch originating from the fornical body to the ipsilateral medial temporal lobe via the splenium of the corpus callosum.
