Query: Geometric renormalization unravels self-similarity of the multiscale
  human connectome   Structural connectivity in the brain is typically studied by reducing its
observation to a single spatial resolution. However, the brain possesses a rich
architecture organized over multiple scales linked to one another. We explored
the multiscale organization of human connectomes using datasets of healthy
subjects reconstructed at five different resolutions. We found that the
structure of the human brain remains self-similar when the resolution of
observation is progressively decreased by hierarchical coarse-graining of the
anatomical regions. Strikingly, a geometric network model, where distances are
not Euclidean, predicts the multiscale properties of connectomes, including
self-similarity. The model relies on the application of a geometric
renormalization protocol which decreases the resolution by coarse-graining and
averaging over short similarity distances. Our results suggest that simple
organizing principles underlie the multiscale architecture of human structural
brain networks, where the same connectivity law dictates short- and long-range
connections between different brain regions over many resolutions. The
implications are varied and can be substantial for fundamental debates, such as
whether the brain is working near a critical point, as well as for applications
including advanced tools to simplify the digital reconstruction and simulation
of the brain.
