Probabilistic tracking (green) based on 64 diffusion gradient orientations showed the dentate‐rubro‐thalamic tract (DRTT) along the same path as deterministic tracking with 12 gradient orientations (yellow). However, the probabilistic approach detected the DRTT in more brains than the deterministic approach. Superior to the ventral thalamus the deterministic solution merged with the pyramidal tract, whereas the probabilistic solution diverged into additional tracts such as the ansa lenticularis.
