graph theory metrics
Mathematical measures characterizing network topology and organization properties.
Full Definition
Graph theory metrics are mathematical measures used to characterize the topological properties of brain networks represented as graphs, where nodes represent brain regions and edges represent connections between them. Common metrics include clustering coefficient (measuring local connectivity), path length (measuring integration), betweenness centrality (identifying hub regions), and modularity (detecting community structure). These metrics provide quantitative frameworks for understanding brain network organization in health and disease. Graph theory analysis has revealed fundamental principles of brain network architecture, including small-world properties, rich-club organization, and hierarchical modularity that support efficient neural communication.
Usage
Usage note: Use plural form 'metrics' when referring to multiple measures; be specific about which metrics are computed.
