ABSTRACT
The macroscopic or network level reflects the combined role of all the connections

number of highly connected nodes or hubs, to a much greater extent than would be
expected of a random graph. In network terms, these hubs exhibit a degree (i.e. num-
ber of connected nodes) that is much higher than other nodes. More generally, the
connectivity of the network has a characteristic distribution, in which the degree of
all nodes in the network follows a truncated power-distribution (Morais et al., 2013).
properties such as small-world organization produce networks that are robust against
damage and allow efficient information distribution (Borge-Holthoefer, Moreno, &
Arenas, 2012). Moreover, small world organization often emerges when a network
forms via growth process, as is the case for other dynamic networks such as networks
Tenenbaum, 2005).
