Dynamic reconfiguration of human brain networks during learning
TLDR
This work investigates the role of modularity in human learning by identifying dynamic changes of modular organization spanning multiple temporal scales and develops a general statistical framework for the identification of modular architectures in evolving systems.
Hierarchical Organization of Human Cortical Networks in Health and Schizophrenia
TLDR
It is proposed that the topological differences between divisions of normal cortex may represent the outcome of different growth processes for multimodal and transmodal networks and that neurodevelopmental abnormalities in schizophrenia specifically impact multi-modal cortical organization.
Small-World Brain Networks
TLDR
The authors consider the relevance of small-world models for understanding the emergence of complex behaviors and the resilience of brain systems to pathological attack by disease or aberrant development and conclude that small- world models provide a powerful and versatile approach to understanding the structure and function of human brain systems.
Functional Connectivity and Brain Networks in Schizophrenia
TLDR
It is concluded that people with schizophrenia tend to have a less strongly integrated, more diverse profile of brain functional connectivity, associated with a less hub-dominated configuration of complex brain functional networks.
Brain graphs: graphical models of the human brain connectome.
TLDR
A conceptual review and methodological guide to graphical analysis of human neuroimaging data, with an emphasis on some of the key assumptions, issues, and trade-offs facing the investigator.
Learning-induced autonomy of sensorimotor systems
TLDR
The results show that learning induces an autonomy of sensorimotor systems and that the release of cognitive control hubs in frontal and cingulate cortices predicts individual differences in the rate of learning on other days of practice.
Adaptive reconfiguration of fractal small-world human brain functional networks
TLDR
Human brain functional networks demonstrate a fractal small-world architecture that supports critical dynamics and task-related spatial reconfiguration while preserving global topological parameters.
Dynamic reconfiguration of frontal brain networks during executive cognition in humans
TLDR
The results characterize dynamic reconfiguration of large-scale distributed neural circuits during executive cognition in humans and have implications for understanding impaired cognitive function in disorders affecting connectivity, such as schizophrenia or dementia.
