DPARSF: a MATLAB toolbox for pipeline data analysis of resting-state fMRI

open access: yesFrontiers in Systems Neuroscience, 2010
Resting-state functional magnetic resonance imaging (fMRI) has attracted more and more attention because of its effectiveness, simplicity and non-invasiveness in exploration of the intrinsic functional architecture of the human brain.

An information-theoretic analysis of resting-state versus task fMRI

open access: yesNetwork Neuroscience, 2023
Resting-state fMRI is an increasingly popular alternative to task-based fMRI. However, a formal quantification of the amount of information provided by resting-state fMRI as opposed to active task conditions about neural responses is lacking.

Compressed Online Dictionary Learning for Fast fMRI Decomposition [PDF]

open access: yes, 2016
We present a method for fast resting-state fMRI spatial decomposi-tions of very large datasets, based on the reduction of the temporal dimension before applying dictionary learning on concatenated individual records from groups of subjects. Introducing a

A Resting-State fMRI Study [PDF]

open access: yes, 2017
Mirror visual feedback (MVF) is a promising approach to enhance motor performance without training in healthy adults as well as in patients with focal brain lesions.

Arousal Contributions to Resting-State fMRI Connectivity and Dynamics

open access: yesFrontiers in Neuroscience, 2019
Resting-state functional magnetic resonance imaging (rsfMRI) is being widely used for charting brain connectivity and dynamics in healthy and diseased brains. However, the resting state paradigm allows an unconstrained fluctuation of brain arousal, which

3T vs. 7T fMRI: capturing early human memory consolidation after motor task utilizing the observed higher functional specificity of 7T

open access: yesFrontiers in Neuroscience, 2023
ObjectiveFunctional magnetic resonance imaging (fMRI) visualizes brain structures at increasingly higher resolution and better signal-to-noise ratio (SNR) as field strength increases.

Hemodynamic and electrophysiological evidence of resting-state network activity in the primate [PDF]

open access: yes, 2008
An expanding body of literature describes the existence of concerted brain activations in the absence of any external stimuli. Resting-state networks have been identified and demonstrated to be modulated during the performance of specific cognitive ...

Group analysis data representing the effects of frontopolar transcranial direct current stimulation on the default mode network

open access: yesData in Brief, 2018
The current data provide information about altered activities of the default mode network (DMN) after applying transcranial direct current stimulation (tDCS) over the frontopolar prefrontal cortex. To explore whether frontopolar tDCS with a small current

fMRI biomarkers of social cognitive skills training in psychosis: Extrinsic and intrinsic functional connectivity. [PDF]

open access: yes, 2019
Social cognitive skills training interventions for psychotic disorders have shown improvement in social cognitive performance tasks, but little was known about brain-based biomarkers linked to treatment effects.

Optimizing Stimulation and Analysis Protocols for Neonatal fMRI [PDF]

open access: yes, 2014
The development of brain function in young infants is poorly understood. The core challenge is that infants have a limited behavioral repertoire through which brain function can be expressed.
