Complex brain networks: graph theoretical analysis of structural and functional systems
This article reviews studies investigating complex brain networks in diverse experimental modalities and provides an accessible introduction to the basic principles of graph theory and highlights the technical challenges and key questions to be addressed by future developments in this rapidly moving field.

N‐back working memory paradigm: A meta‐analysis of normative functional neuroimaging studies
One of the most popular experimental paradigms for functional neuroimaging studies of working memory has been the n‐back task, in which subjects are asked to monitor the identity or location of aExpand
A Resilient, Low-Frequency, Small-World Human Brain Functional Network with Highly Connected Association Cortical Hubs
It is concluded that correlated, low-frequency oscillations in human fMRI data have a small-world architecture that probably reflects underlying anatomical connectivity of the cortex, and could provide a physiological substrate for segregated and distributed information processing. Expand
Efficiency and Cost of Economical Brain Functional Networks
Efficiency was reduced disproportionately to cost in older people, and the detrimental effects of age on efficiency were localised to frontal and temporal cortical and subcortical regions. Expand
Network-based statistic: Identifying differences in brain networks
The network-based statistic (NBS) is introduced for the first time and its power is evaluated with the use of receiver operating characteristic (ROC) curves to demonstrate its utility with application to a real case-control study involving a group of people with schizophrenia for which resting-state functional MRI data were acquired. Expand
The economy of brain network organization
It is proposed that brain organization is shaped by an economic trade-off between minimizing costs and allowing the emergence of adaptively valuable topological patterns of anatomical or functional connectivity between multiple neuronal populations. Expand
Integrating evidence from neuroimaging and neuropsychological studies of obsessive-compulsive disorder: The orbitofronto-striatal model revisited
A quantitative, voxel-level meta-analysis of functional MRI findings revealed consistent abnormalities in orbitofronto-striatal and other additional areas in OCD, which is considered a timely assessment of neuroimaging findings to date. Expand
Neurophysiological architecture of functional magnetic resonance images of human brain.
Functional MRI demonstrates a neurophysiological architecture of the normal human brain that is anatomically sensible, strongly symmetrical, disrupted by acute brain injury, subtended predominantly by low frequencies and consistent with a small world network topology. Expand
Stop-signal inhibition disrupted by damage to right inferior frontal gyrus in humans
This work uses a new observer-independent method to relate the degree of damage within a specific prefrontal region to performance on a stop-signal task that is sensitive to the neurodevelopmental aspects of stopping behavior and to attention-deficit/hyperactivity disorder (ADHD) as well as its amelioration by methylphenidate.
