  Greedy navigation/routing plays an important role in geometric routing of
networks because of its locality and simplicity. This can operate in
geometrically embedded networks in a distributed manner, distances are
calculated based on coordinates of network nodes for choosing the next hop in
the routing. Based only on node coordinates in any metric space, the Greedy
Navigational Core (GNC) can be identi ?ed as the minimum set of links between
these nodes which provides 100% greedy navigability. In this paper we perform
results on structural greedy navigability as the level of presence of Greedy
Navigational Cores in structural networks of the Human Brain.
