1/6: Excited to share final version of our new hierarchical SUBCORTEX ATLAS in @NatureNeuro

27 new functional regions organize across 4 scales and adapt to changing cognitive demands

Well done @yetianmed

2/6: Scales I-IV of our atlas are freely available in CIFTI & NIFTI formats.

We have also integrated our atlas into existing cortex-only atlases (e.g. Gordon, Glasser) to enable whole-brain connectome mapping:

3/6: We used model selection to reconcile two complementary models of brain topography: continuous GRADIENTS and discrete BOUNDARIES.

Boundaries are only drawn if local gradients are sharper than expected under a null model (gray curves in the image).
4/6: Using machine learning techniques, we personalized the group-consensus atlas to account for individual differences in connectivity. All regions were detected in unseen individuals.
5/6: Connectivity gradients varied dynamically in response to changing cognitive demands. For example, the anterior hippocampus became more integrated with the amygdala during task engagement, compared to rest.
