From these functional brain networks, a number of key characteristics that describe the overall organization of a network were computed, including the clustering coefficient C and characteristic path length L (Watts and Strogatz, 1998).

Neuroimaging studies have linked intelligence to the developmental course of specific high - order brain regions (Shaw et al., 2006), total brain volume and focal brain structure (Thompson et al., 2001; Haier et al., 2004; Colom et al., 2006; Hulshoff Pol et al., 2006; Choi et al., 2008), microstructural organization of white matter (Chiang et al., 2009), and the functional dynamics of specific high cognitive brain regions (Duncan et al., 2000; Gray et al., 2003; Choi et al., 2008; Song et al., 2008).

The functional brain networks showed a clear small - world organization, expressed by λ ≈ 1 (c) and γ ≫ 1 (d) for T ≥ 0.3 (1 - sample t test, df = 18, all p < α of 0.01, Bonferroni corrected for multiple comparisons of T).

The organization of the functional brain network was examined using graph theory (Achard et al., 2006; Stam and Reijneveld, 2007; Bullmore and Sporns, 2009), as validated earlier (van den Heuvel et al., 2008b)(supplemental material, available at www.jneurosci.org).

The functional brain networks showed a clear small - world organization for 0.3 ≤ T ≤ 0.5 (Fig. 1a — d), expressed by L ≈ Lrandom and λ ≈ 1 for T ≤ 0.5 and C ≫ Crandom and γ ≫ 1 for T ≥ 0.3 (one - sample t test, all p < α of 0.01, Bonferroni corrected for multiple comparisons of T, df = 18), indicating a small - world organization (Sporns et al., 2004; Stam, 2004; Achard et al., 2006; van den Heuvel et al., 2008b).

Therefore future studies are needed to examine whether common genes mediate the association between functional and structural brain network organization and intelligence.

Such an efficient organization of our brain network raises the question of a possible relationship between how efficiently the functional connections of our brain are placed and individual differences in intelligence.

Our data reflects the level of efficient organization of the functional brain network during a resting state and not the efficiency of functional connectivity between brain regions during the performance of specific cognitive tasks that enter into the IQ score.

Recently, functional network connectivity (FNC, defined as the temporal correlation among spatially distant brain networks) has been used to examine the functional organization of brain networks in

It investigates the human brain, from the functional organization of large scale cerebral systems to microscopic neurochemical processes.

Altered functional and structural brain network organization in autism.

Our study provides new evidence that there is disrupted organization of functional brain networks in AD.
