Functional network connectivity alterations in schizophrenia and depression [PDF]

Psychiatry Research - Neuroimaging, 2017
There is a high degree of overlap between the symptoms of major depressive disorder (MDD) and schizophrenia, but it remains unclear whether the similar symptoms are derived from convergent alterations in functional network connectivity. In this study, we performed a group independent component analysis on resting-state functional MRI data from 20 MDD ...

Abnormal functional connectivity of the salience network in insomnia

Brain Imaging and Behavior, 2021
The salience network plays an important role in detecting stimuli related to behavior and integrating neural processes. The aim of this study was to investigate changes in functional connectivity of the salience network in insomnia patients. Independent component analysis combined with a dual regression approach was used to examine functional ...

NATURAL TOLERANCE AS A FUNCTION OF NETWORK CONNECTIVITY

International Journal of Bifurcation and Chaos, 1996
This article investigates the following basic question: in the relatively stable molecular environment of a vertebrate body, can a dynamic idiotypic immune network develop a natural tolerance to endogenous components? Our approach is based on stability analysis and computer simulation using a model that takes into account the dynamics of two agents of

Construction of Functional Brain Connectivity Networks

2015
Graph theory and the study of complex networks have, over the last decade, received increasing attention from the neuroscience research community. It allows for the description of the brain as a full network of connections, a connectome, as well as for the quantitative characterization of its topological properties.

Functional network connectivity in early-stage schizophrenia

Schizophrenia Research, 2020
Schizophrenia is a disorder of altered neural connections resulting in impaired information integration. Whole brain assessment of within- and between-network connections may determine how information processing is disrupted in schizophrenia. Patients with early-stage schizophrenia (n = 56) and a matched control sample (n = 32) underwent resting-state ...

Fitting networks models for functional brain connectivity

2017 IEEE 14th International Symposium on Biomedical Imaging (ISBI 2017), 2017
Functional connectivity of the human brain and the hierarchical modular architecture of functional networks can be investigated using functional magnetic resonance imaging (fMRI). Various network models, such as power-law networks and modular networks have been explored before to study brain networks.

Dynamic functional network connectivity alterations in obesity

Diabetes, Obesity and Metabolism
Abstract Aims Obesity involves both metabolic and neural dysfunction, yet the temporal dynamics of brain connectivity remain unclear. This study applied dynamic functional network connectivity (dFNC) analysis to reveal time‐varying brain network patterns in obesity.

Blinking Long-Range Connections Increase the Functionality of Locally Connected Networks

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2005
Information processing with only locally connected networks such as cellular neural networks is advantageous for integrated circuit implementations. Adding long range connections can often enhance considerably their performance. It is sufficient to activate these connections randomly from time to time (blinking connections).

Functional network connectivity in the behavioral variant of frontotemporal dementia

Cortex, 2013
The aim of this study was to investigate, using resting state (RS) functional magnetic resonance imaging (fMRI), the functional connectivity within and among brain networks in patients with the behavioral variant of frontotemporal dementia (bvFTD), compared with healthy controls and patients with probable Alzheimer's disease (pAD).Twelve bvFTD patients

Brain Network Functional Connectivity in Children With a Concussion

Neurology
Pediatric concussion can disrupt functional brain network connectivity, but prospective longitudinal research is needed to clarify recovery and identify moderators of change. This study investigated network functional connectivity (FC) up to 6 months after pediatric concussion.This prospective longitudinal concurrent cohort observational study ...
