Using Graph Theory to Assess the Interaction between Cerebral Function, Brain Hemodynamics, and Systemic Variables in Premature Infants

Figure 3

Physiological network representing the interaction between 5 signal modalities recorded on a neonate after propofol administration. The graph consists of 5 vertices, corresponding to the signal modalities. In addition, an edge is present between every pair of nodes (complete graph). Each edge is defined by a weight value that represents the interaction between the corresponding signal modalities.
