Manual annotation of the Nucleus accumbens in balanced demographic data

We utilized data from the Human Connectome Project (HCP) Young Adult dataset. The T1-weighted MRIs have a resolution of \( 260 \times 311 \times 260 \) voxels with an isotropic voxel spacing of \( 0.7 \). The subjects' ages ranged from 22 to 35. Reporting race and ethnicity in this study was mandated by the NIH, consistent with the Inclusion of Women, Minorities, and Children policy. Sex, race and ethnicity were self-reported by participants. We utilized the manual segmentations of two subcortical structures, the right and left nucleus accumbens (NAc), provided by neuroanatomist Dr. Jarrett Rushmore. This structure was selected due to previously reported sex differences in microstructure and its role in the human reward system.
