information flow or network integrity, which parts of functional networks are better structured for local versus global processes, and what types of processes could give rise to observed network structures. Recent graph theoretic studies have begun to explore such issues in adult brain networks (for review, see Bullmore & Sporns, 2009 (Bullmore and Sporns, 2009)), and here we focus on studies that examine functional networks in children (often in comparison with adults). This review will introduce several aspects of graph theory in the following section, but interested readers are referred to Newman, 2010 (Newman, 2010) for a fuller introduction to the field, and to Rubinov, 2009 (Rubinov and Sporns, 2009) for a discussion of graph theoretic measures in the context of MRI data.
