NeuroImage, 2014 This technical note introduces a dynamic causal model (DCM) for resting state fMRI time series based upon observed functional connectivity--as measured by the cross spectra among different brain regions. This DCM is based upon a deterministic model that generates predicted crossed spectra from a biophysically plausible model of coupled neuronal ...

Functional Connectivity Hubs and Networks in the Awake Marmoset Brain
Frontiers in Integrative Neuroscience, 2016 In combination with advances in analytical methods, resting-state fMRI is allowing unprecedented access to achieve a better understanding of the network organization of the brain. Increasing evidence suggests that this architecture may incorporate highly

Similarities and differences between intermittent and continuous resting-state fMRI
Frontiers in Human Neuroscience, 2023 IntroductionFunctional Magnetic Resonance Imaging (fMRI) block-design experiments typically include active ON-blocks with presentation of cognitive tasks which are contrasted with OFF- blocks with no tasks presented.

Resting-state Networks in Tinnitus
Clinical Neuroradiology, 2022 AbstractChronic subjective tinnitus is the constant perception of a sound that has no physical source. Brain imaging studies show alterations in tinnitus patients’ resting-state networks (RSNs). This scoping review aims to provide an overview of resting-state fMRI studies in tinnitus, and to evaluate the evidence for changes in different RSNs.

Resting state cortical electroencephalographic rhythms in covert hepatic encephalopathy and Alzheimer's disease [PDF]
, 2013 Patients suffering from prodromal (i.e., amnestic mild cognitive impairment, aMCI) and overt Alzheimer's disease (AD) show abnormal cortical sources of resting state electroencephalographic (EEG) rhythms.

Test–Retest Reliability of Synchrony and Metastability in Resting State fMRI
Brain Sciences, 2021 In recent years, interest has been growing in dynamic characteristic of brain signals from resting-state functional magnetic resonance imaging (rs-fMRI). Synchrony and metastability, as neurodynamic indexes, are considered as one of methods for analyzing

Therapeutic Advances in Psychopharmacology, 2023 Background: Altered resting-state functional connectivity has been found in patients with post-traumatic stress disorder (PTSD). However, the alteration of resting-state functional connectivity at whole-brain level in typhoon-traumatized individuals with

Disruption of brain connectivity in acute stroke patients with early impairment in consciousness
Frontiers in Psychology, 2014 Impairment in consciousness is common in acute stroke patients and is correlated with the clinical outcome after stroke. The underlying mechanism is not completely understood, with little known about brain activity and connectivity changes in acute ...
