Aim: Capture the many facets of human
brain organization in a common framework
                • Multiple scales
                 Link the cellular scale to the
                 macroscopic scale

                • Multiple maps
                 Provide complementary
                 brain parcellations

                • Multimodal features
                 Provide a framework for linking
                 data features to brain regions

Some use cases

                 27
Some usecases
• Experimental neuroscience: Integrate data from
  experiments into a common reference space
• Data analysis: Use atlases and data features to run
  reproducible neuroscience experiments
• Brain simulation and biologically inspired AI:
  Understanding the structure of biological networks
• Hospitals: Planning surgeries, comparing diseased to
  healthy brains, anatomical location assignment
• Education: Studying brain anatomy
