FIG. 5.

Pathway estimate comparison. Examples of the streamlines associated with different axonal pathways, as simulated by different modeling methods from a single representative subject. All of the methods generated reasonable approximations of the CST (red: face, green: arm, blue: leg streamlines). Whole-brain tractography was not effective at reconstructing the CBT (orange streamlines) or PT (blue streamlines) pathways. Manual tractography generated reasonable approximations of the CBT pathway, but failed to capture the anatomical trajectory of the PT pathway. Yellow volume: thalamus, red volume: red nucleus, blue volume: pallidum.
