Abstract

The anatomical arrangement of the human brain can be considered as a network, where distinct regions on the surface of the cortex (grey matter) are considered as nodes, and the set of white matter bundles in between them are taken as edges. A feature common to all structural brain networks is that of hubs: a small set of highly connected or highly important nodes. The present paper reviews how these structures are defined in neuroscientific studies, as well as the nature of their topological importance. It further examines the notion that hubs do not change through the course of development by contrasting the findings and methodologies of the existing literature.
