Little2024_HBM Release - Mapping caudolenticular gray matter bridges in the human brain striatum through diffusion magnetic resonance imaging and tractography

Accompanying dataset for Little 2024 - Human Brain Mapping.

Dataset includes, derived maps and tractograms for the 760um (3 sessions, same subject) and HCP Test-Retest cohort (44 subjects, scanned twice each) datasets used in the associated experiments.

Within each subject/scan folder:

• DTI_maps - derived dti maps calculated from the b0 and b1000 images
• meanDWI - average diffusion weighted and non-diffusion weighted images
• T2 - whole brain structural T2 weighted images useful for anatomical reference
• CLGB_trk - tractogram reconstructions for the left/right caudolenticular gray matter bridges reconstructed using the proposed seeding/filtering strategy

Note: to reduce the overal file size, T2 images from the HCP dataset were only included for subject #103818. The entire datset can be found here (https://www.humanconnectome.org/study/hcp-young-adult/data-releases)
