DESCRIPTION:I will review recent results on the topology and spatial organ
 ization of brain networks\, mainly based on human neuroimaging data in hea
 lth and disease. It turns out that brain networks consistently express non
 -random topological features\, such as small-worldness\, hubs\, modules an
 d rich clubs. Some of these features entail disproportionate biological co
 st but may be "worth it" by supporting integrative information processing 
 and adaptive behaviours. Highly connected hub nodes are high cost / high v
 alue\nnetwork components that likely also represent special points of vuln
 erability for diverse brain disorders. These economical principles of brai
 n network organization are expressed at microscopic scale\, e.g.\, in the 
 nervous system of the nematode worm C. elegans\, and may therefore provide
  a new axis for translation between macro and micro systems\nneuroscience.
