Static and Dynamic Cross‐Network Functional Connectivity Shows Elevated Entropy in Schizophrenia Patients [PDF]
Human Brain MappingABSTRACT Schizophrenia (SZ) patients exhibit abnormal static and dynamic functional connectivity across various brain domains. We present a novel approach based on static and dynamic inter‐network connectivity entropy (ICE), which represents the entropy of a given network's connectivity to all the other brain networks.

Differences in dynamic and static functional connectivity between young and elderly healthy adults
Neuroradiology, 2017Brain connectivity is highly dynamic, but functional connectivity (FC) studies using resting-state functional magnetic resonance imaging (rs-fMRI) assume it to be static. This study assessed differences in dynamic FC between young healthy adults (YH) and elderly healthy adults (EH) compared to static FC.Using rs-fMRI data from 12 YH and 31 EH, FC was ...

Altered static brain activity and functional connectivity after heat stroke
NeuroReportThis study aimed to investigate the alteration of brain function based on resting-state functional MRI in patients after heat stroke. This study included 10 cases of patients after heat stroke and 10 cases of healthy controls. Abnormal brain function was calculated using amplitude of low-frequency fluctuations (ALFF) and degree centrality analysis, as ...

Functional Connectivity of the Brain: Reconstruction from Static and Dynamic Data
2006The central nervous system is a single complex network connecting each neuron through a number of synaptic connections. However, only a small fraction of the total connections functionally link neurons together. If the smallest multineuronal architecture within which functional links are established constitutes circuitry, then what are the basic ...

Altered Static and Dynamic Functional Network Connectivity and Combined Machine Learning in Stroke
Brain TopographyStroke is a condition characterized by damage to the cerebral vasculature from various causes, resulting in focal or widespread brain tissue damage. Prior neuroimaging research has demonstrated that individuals with stroke present structural and functional brain abnormalities, evident through disruptions in motor, cognitive, and other vital functions ...

Altered static and dynamic functional network connectivity and combined Machine learning in asthma
NeuroscienceAsthma is a reversible disease characterized by airflow limitation and chronic airway inflammation. Previous neuroimaging studies have shown structural and functional abnormalities in the brains of individuals with asthma. However, earlier research has primarily focused on static changes in brain activity, neglecting the effects of asthma on the ...

Aberrant alterations of static and dynamic functional connectivity in chronic low back pain
NeuroscienceChronic low back pain (CLBP) is a common disease with uncertain pathological mechanisms, resulting in significant social and economic burdens. Despite the identification of abnormal static functional connectivity (sFC) in brain regions related to pain through neuroimaging studies, the dynamic functional connectivity (dFC) in CLBP has not been ...

Connectivity Analysis of Human Functional MRI Data: From Linear to Nonlinear and Static to Dynamic
2006In this paper, we describe approaches for analyzing functional MRI data to assess brain connectivity. Using phase-space embedding, bivariate embedding dimensions and delta-epsilon methods are introduced to characterize nonlinear connectivity in fMRI data.
