Graph signal processing extends the notion of frequency from signals in the time domain to signals defined on graphs. Graph signals arise in many applications including brain signals defined on functional connectivity networks. Most of the current work on graph signal processing focuses on static graphs. However, functional connectivity networks are dynamic and the signals on these networks change...
The functional connectivity of the human brain may be described by modeling interactions among its neural assemblies as a graph composed of vertices and edges. It has recently been shown that functional brain networks belong to a class of scale-free complex networks for which graphs have helped define an association between function and topology. These networks have been shown to possess a heterogenous...
Determining the functional relationships between nodes in complex networks such as the neuronal networks is important. In recent years, graph theory has been employed to characterize the functional network structure of the brain from neurophysiological data such as the electroencephalogram (EEG). Current work on graph theoretic analysis of brain networks focuses on global characteristics of the network...
