Diffusion Tensor Imaging (DTI) tractography used for the visualization of cranial nerves has mostly focused on tracts inside the brain. This work focuses on tracking trigeminal nerve branches using DTI outside the brain. Trigeminal nerve efferents in the face can be stimulated using transdermal electrical neuromodulation. Locations of subcutaneous tracts of the ophthalmic and maxillary branches of the trigeminal nerve may assist with electrode placement in these studies. Here, we describe use of HARDI-derived DTI to determine locations of trigeminal nerve projections in the face.
