Application of Graph Theory for Identifying Connectivity Patterns in Human Brain Networks: A Systematic Review

Frontiers in Neuroscience, Journal Year: 2019, Volume and Issue: 13

Published: June 6, 2019

Background: Analysis of the human connectome using functional magnetic resonance imaging (fMRI) started in mid-1990s and attracted increasing attention attempts to discover neural underpinnings cognition neurological disorders. In general, brain connectivity patterns from fMRI data are classified as statistical dependencies (functional connectivity) or causal interactions (effective among various units. Computational methods, especially graph theory-based have recently played a significant role understanding architecture. Objectives: Thanks emergence theoretical analysis, main purpose current paper is systematically review how properties can emerge through distinct neuronal units cognitive applications fMRI. Moreover, this article provides an overview existing effective methods used construct network, along with their advantages pitfalls. Methods: systematic review, databases Science Direct, Scopus, arXiv, Google Scholar, IEEE Xplore, PsycINFO, PubMed, SpringerLink employed for exploring evolution computational 1990 present, focusing on theory. The Cochrane Collaboration's tool was assess risk bias individual studies. Results: Our results show that theory its implications neuroscience researchers since 2009 (as Human Connectome Project launched), because prominent capability characterizing behavior complex systems. Although approach be generally applied either during rest task performance, date, most articles focused resting-state connectivity. Conclusions: This insight into utilize measures make neurobiological inferences regarding mechanisms underlying well different

Childhood socio-economic status (SES), a measure of the availability material and social resources, is one strongest predictors lifelong well-being. Here we review evidence that experiences associated with childhood SES affect not only outcome but also pace brain development. We argue higher protracted structural development prolonged trajectory functional network segregation, ultimately leading to more efficient cortical networks in adulthood. hypothesize greater exposure chronic stress accelerates maturation, whereas access novel positive decelerates maturation. discuss impact variation on plasticity learning. provide generative theoretical framework catalyse future basic science translational research environmental influences Evidence suggests can its rate.

Movies in the magnet: Naturalistic paradigms in developmental functional neuroimaging

Published: Nov. 20, 2018

The use of movie-watching as an acquisition state for functional connectivity (FC) MRI has recently enabled multiple groups to obtain rich data sets in younger children with both substantial sample sizes and scan durations. Using naturalistic paradigms such movies also provided analytic flexibility these developmental studies that extends beyond conventional resting approaches. This review highlights the advantages challenges using neuroimaging explores some methodological issues involved designing pediatric movies. Emerging themes from are discussed, including emphasis on intersubject correlations, changes network interactions under complex conditions, dynamic age-related sensory higher-order FC even narrow age ranges. Converging evidence suggests enhanced ability identify brain-behavior correlations when relative tasks. Future directions cautionary notes highlight potential limitations study populations.

The development of brain network hubs

Developmental Cognitive Neuroscience, Journal Year: 2018, Volume and Issue: 36, P. 100607 - 100607

Published: Dec. 13, 2018

Some brain regions have a central role in supporting integrated function, marking them as network hubs. Given the functional importance of hubs, it is natural to ask how they emerge during development and consider shape function maturing brain. Here, we review evidence examining both structural connectivity networks, develop over prenatal, neonate, childhood, adolescent periods. The available suggests that hubs arise prenatal period show consistent spatial topography through development, but undergo protracted consolidation extends into late adolescence. In contrast, networks more variable topography, being predominantly located primary cortical areas early before moving association by childhood. These findings suggest while basic anatomical infrastructure may be established early, viability integrative capacity these undergoes extensive postnatal maturation. Not all are with this view however. We methodological factors might drive inconsistencies, which should addressed promote rigorous investigation development.
