Not exact matches

A new study by University of Illinois researchers found that monounsaturated fatty acids — a class of nutrients found in olive oils, nuts and avocados — are linked to general intelligence, and that this relationship is driven by the correlation between MUFAs and the organization of the brain's attention network.

The researchers used imaging technology that tracks both brain blood flow — as a measure of energy use — and the organization and strength of connections within intrinsic neural networks.

Their findings: activity dropped in the prefrontal cortex — which is implicated in planning as well as in the organization of functions performed by other brain regions — but it jumped in a cluster of brain regions implicated in daydreaming known as the «default mode network.»

To point out which specific brain regions have the strongest association between global network organization and IQ, an exploratory analysis was conducted, in which the normalized path length of each individual node (i.e., voxel) was correlated with IQ separately (supplemental material, available at www.jneurosci.org).

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).

To examine the relationship between the organization of the brain network and intelligence, the computed λ and γ values of the individual brain networks were correlated with the measured full - scale IQ scores of the participants.

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).

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.

To further probe which specific brain regions have the strongest association between global network organization and IQ, the normalized path length of each individual node (i.e., voxel) was correlated with the full - scale IQ scores separately.

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.

Examining the overall organization of the brain network using graph analysis, we show a strong negative association between the normalized characteristic path length λ of the resting - state brain network and intelligence quotient (IQ).

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

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

Small - world metrics can characterize the functional organization of the brain in AD, and our findings further suggest that these network measures may be useful as an imaging - based biomarker to distinguish AD from healthy aging.

Therefore, when functional brain networks are constructed at the voxel - level, a resolution similar to ICA, a network based approach offers distinct advantages over ICA in understanding the overall organization of the brain network.

Even though both ICA and graph theory - based network approach can find similar organization structure in the brain, a network approach offers two advantages.
