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 identified 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
