Modular structure of complex brain networks

Modularity seems to be a key element of complex biological systems to achieve stability and robustness to changing environments. I analyze the modular structure of anatomical and functional brain networks by means of a random walk-based method. The modules of brain-webs present a spatial distribution fitting well anatomical structures with functional significance. Results from neurological patients and healthy subjects suggest that brain modularity constitutes the structural basis for the functional integration of distant and specialized brain areas during both normal and pathological brain activities.
