Human brain connectivity networks with graph theory 

Noninvasive neuroimaging of the brain while functioning is providing very promising data sets to study the complex organisation of brain areas. It is not only possible to identify responses of brain areas to a cognitive stimulus but also to model the interactions between brain areas. The human brain can be modelled as a network or graph where brain areas are nodes of the graph and interactions of pairs are the edges of the graph. The brain connectivity networks is small-world with a combination of segregation and integration characteritics. In this talk, I will present a description of the brain connectivity network using graph theory. Examples on various pathologies will highlight the possible alterations and resilience of the brain network. A particular focus will be provided on brain connectivity networks for patients with consciousness disorders.
