Increasingly, science is concerned with the structure, behavior, andevolution of complex systems ranging from cells to ecosystems. The integrative nature ofbrain function, for example, can be illuminated from a complex network perspective. Astudy published recently illustrates how networks connect levels of organization in thebrain and how they link structure to function. This approach provides a synthesis of thesciences of complex networks and the brain that will be an essential foundation for futureresearch.
