Interest in brain network studies has increased strongly with the advent of modern network theory and increasingly powerful investigative techniques such as "highdensity EEG", MEG, functional and structural ...
In addition to the already established network models, we suggest a heuristic model including hierarchical modularity. a b s t r a c t One of the central questions in neuroscience is how communication ...
To a large extent, structural and functional studies reveal the same complex and in particular hierarchical network structure of the brain at multiple levels (Bassett et al., 2008) . ...

Connectomic neural analyses, informed by social network theory, may be helpful in understanding underlying fundamental principles of brain organization. ...
In Figure 8 , we have placed in the southeast the diffuse networks that Lieberman et al. (2005) identify with drift and in the northeast the hierarchical networks they associate with selection. ...
