Fig. 1. Ground truth fiber pathways for all sub-challenges.

Fig. 1.

The macaque challenge ground truth (A) is derived from tracer studies for both the PCG (red labels) and V4v (yellow labels) pathways, with seed region for PCG shown as a blue label. The squirrel monkey ground truth is derived from histological tracer density maps from the same subject (B), and visualized as a 3D volume rendering (C), with seed/injection regions shown in blue. The phantom (D) ground truth for all bundles is derived from manual tracing on a high resolution T1 weighted image (E).
