ABSTRACT
The brain is first and foremost a network of interacting biological elements. This simple observation motivates the use of network analytical methods in neuroimaging. Specifically, brain activity is assumed to originate with the interactions of a very large number of individual neurons. Moreover, other patterns of interaction have also generated some interest
of
in the literature, including the network formed by neuroglial cells. These microscale networks are naturally of critical importance to aid our understanding of motor and cognitive brain functions. Neuroimaging and neuroanatomy have shown that such microscale networks are integrated into larger-scale networks of cortical and subcortical regions. It is these macroscale networks that will be discussed in the chapter at hand.
