Basal ganglia structures, globus pallidus internal, globus pallidus external, subthalamic nucleus, substantia nigra, red nucleus and striatum were automatically segmented on 3T and 7T HCP preprocessed diffusion weighted images. Connectivity between each basal ganglia structure was observed using probabilistic tractography generated with FSL's diffusion tools such as BEDPOSTX and PROBTRACKX. Tractography between basal ganglia was compared between 3T and 7T to observe differences that arise from tradeoffs of each acquisition.
