rsHRF: A toolbox for resting-state HRF estimation and deconvolution

NeuroImage, 2021
The hemodynamic response function (HRF) greatly influences the intra- and inter-subject variability of brain activation and connectivity, and might confound the estimation of temporal precedence in connectivity analyses, making its estimation necessary ...

Network connectivity in epilepsy: Resting state-fMRI and EEG-fMRI contributions

Frontiers in Neurology, 2014
There is a growing body of evidence pointing towards large scale networks underlying the core phenomena in epilepsy, from seizure generation to cognitive dysfunction or response to treatment.

State-Dependent Effective Connectivity in Resting-State fMRI

Frontiers in Neural Circuits, 2021
The human brain at rest exhibits intrinsic dynamics transitioning among the multiple metastable states of the inter-regional functional connectivity. Accordingly, the demand for exploring the state-specific functional connectivity increases for a deeper ...

Resting State fMRI Reveals Diminished Functional Connectivity in a Mouse Model of Amyloidosis [PDF]

, 2013
Introduction: Functional connectivity (FC) studies have gained immense popularity in the evaluation of several neurological disorders, such as Alzheimer’s disease (AD). AD is a complex disorder, characterised by several pathological features. The problem

The VWFA: It’s Not Just for Words Anymore

Frontiers in Human Neuroscience, 2014
Reading is an important but phylogenetically new skill. While neuroimaging studies have identified brain regions used in reading, it is unclear to what extent these regions become specialized for use predominantly in reading versus other tasks.

Noncoding transcripts are linked to brain resting-state activity in non-human primates

Cell Reports, 2023
Summary: Brain-derived transcriptomes are known to correlate with resting-state brain activity in humans. Whether this association holds in nonhuman primates remains uncertain.

Cortical sources of resting state EEG rhythms are sensitive to the progression of early stage Alzheimer's disease [PDF]

, 2013
Cortical sources of resting state electroencephalographic (EEG) rhythms are abnormal in subjects with Alzheimer's disease (AD). Here we tested the hypothesis that these sources are also sensitive to the progression of early stage AD over the course of ...

A DCM for resting state fMRI

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.
