Efficiency and Cost of Economical Brain Functional Networks
Brain anatomical networks are sparse, complex, and have economical small-world properties. We investigated the efficiency and cost of human brain functional networks measured using functional magnetic resonance imaging (fMRI) in a factorial design: two groups of healthy old (N = 11; mean age = 66.5 years) and healthy young (N = 15; mean age = 24.7 years) volunteers were each scanned twice in a ...
متن کاملIncreased Cost Efficiency of Economical Brain Structural Networks in the Early Developing Brain
Introduction: Brain networks are the graph representation of brain regional connectivity which is typically estimated as the correlation between regional measures of brain structure and function using imaging analysis techniques [1]. Recent studies have shown that brain anatomical and functional networks as studied with MRI, EEG, MEG, and functional MRI often exhibit so called small-world netwo...
متن کاملMaterial of Efficiency of functional brain networks and intellectual performance
Supplemental Materials and Methods Data acquisition Resting state fMRI. Our brain is a complex dynamic system in which information is continuously processed and transferred between brain regions with highly correlated functional dynamics (Sporns et al., 2000; Sporns et al., 2004). These coherent dynamics are believed to reflect the existence of functional connections between these regions. Func...
متن کاملEfficiency of functional brain networks and intellectual performance.
Our brain is a complex network in which information is continuously processed and transported between spatially distributed but functionally linked regions. Recent studies have shown that the functional connections of the brain network are organized in a highly efficient small-world manner, indicating a high level of local neighborhood clustering, together with the existence of more long-distan...
متن کاملCognitive fitness of cost-efficient brain functional networks.
The human brain's capacity for cognitive function is thought to depend on coordinated activity in sparsely connected, complex networks organized over many scales of space and time. Recent work has demonstrated that human brain networks constructed from neuroimaging data have economical small-world properties that confer high efficiency of information processing at relatively low connection cost...
