A detailed atlas of the human brain that integrates information on brain structure, function, and connectivity across multiple modalities and spatial scales.

  • Probabilistic 3D maps of cytoarchitecture, fiber bundles and functional modules, capturing cross-subject variability.
  • Integration of the microscopic 3D model “BigBrain” with the MNI and freesurfer reference spaces, linking macroanatomy with cellular detail.
  • Measures of molecular, cellular and fiber architecture, characterizing the composition and intrinsic variance of brain regions.
  • Structural and functional connectivity from different neuroimaging cohorts.

The EBRAINS multilevel human brain atlas provides detailed information on anatomy, connectivity, and function. It links macroanatomical concepts and their intersubject variability with measurements of the microstructural composition and intrinsic variance of brain regions.


Explore the different facets of human brain organisation

The multilevel human brain builds on the Julich-Brain cytoarchitectonic maps as a unifying principle of organisation, which are defined at the microscopic scale and well established as a reference for anatomical assignment of neuroimaging signals. The maps reflect intersubject variability in space and localization (“probability maps”).

They are complemented with maps covering complementary aspects of brain organisation, represented by fiber bundles from MRI tractography and maps of functional modes. The atlas supports multiple reference spaces, including the MNI Colin27, ICBM 152 2009c and average spaces which are common in functional imaging and whole-brain connectivity studies. It integrates these with the microscopic resolution BigBrain model as a link from the macroscopic to the cellular scale. Brain regions are characterised by multiple levels of brain connectivity and multimodal regional measurements including neurotransmitter receptor densities, cell densities, fiber orientations, genomics and physiological data.
