The conundrum of functional brain networks: Small-world efficiency or fractal modularity
(Frontiers Editorial, 2012-05)
The human brain has been studied at multiple scales, from neurons, circuits, areas with well-defined anatomical and functional boundaries, to large-scale functional networks which mediate coherent cognition. In a recent ...
Ising-like dynamics in large-scale functional brain networks
(American Physical Society, 2009-12)
Brain "rest" is defined-more or less unsuccessfully-as the state in which there is no explicit brain input or output. This work focuses on the question of whether such state can be comparable to any known dynamical state. ...
Default Mode, Executive Function, and Language Functional Connectivity Networks are Compromised in Mild Alzheimer's Disease
(Bentham Science Publ LtdSharjahEmirados Árabes Unidos, 2014)
Brain Organization into Resting State Networks Emerges at Criticality on a Model of the Human Connectome
(Amer Physical Soc, 2013-04-26)
The relation between large-scale brain structure and function is an outstanding open problem in neuroscience. We approach this problem by studying the dynamical regime under which realistic spatiotemporal patterns of brain ...
From brain-body function to conscious interactions
In this review, we discuss empirical results inspiring the introduction of a formal mathematical multilayer model for the biological neuroscience of conscious experience. First, we motivate the discussion through evidence ...
Avoiding catastrophic failure in correlated network of networks
(Nature Publishing Group, 2014-09)
Networks in nature do not act in isolation, but instead exchange information and depend on one another to function properly1–3 . Theory has shown that connecting random networks may very easily result in abrupt failures3–6. ...
Variability in functional brain networks predicts expertise during action observation
(Academic Press Inc Elsevier Science, 2016-09)
Observing an action performed by another individual activates, in the observer, similar circuits as those involved in the actual execution of that action. This activation is modulated by prior experience; indeed, sustained ...
Learning about brain physiology and complexity from the study of the epilepsies
(Associação Brasileira de Divulgação Científica, 2009)
The brain is a complex system, which produces emergent properties such as those associated with activity-dependent plasticity in processes of learning and memory. Therefore, understanding the integrated structures and ...
Large-scale Brain Networks Are Distinctly Affected In Right And Left Mesial Temporal Lobe Epilepsy
