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 ...

Lag structure in resting-state fMRI

open access: yesJournal of Neurophysiology, 2014
The discovery that spontaneous fluctuations in blood oxygen level-dependent (BOLD) signals contain information about the functional organization of the brain has caused a paradigm shift in neuroimaging. It is now well established that intrinsic brain activity is organized into spatially segregated resting-state networks (RSNs). Less is known regarding

Temporal dynamics in fMRI resting-state activity [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
In a significant new study, Mitra et al. (1) demonstrate the existence of reproducible temporal patterns of spontaneous activity from human functional magnetic resonance imaging (fMRI) recordings. This finding and the novel methods used to demonstrate it bring the question of the role of temporally patterned activity into the domain of human cognition.

Monkey in the middle: why non-human primates are needed to bridge the gap in resting-state investigations [PDF]

open access: yes, 2012
Resting-state investigations based on the evaluation of intrinsic low-frequency fluctuations of the BOLD fMRI signal have been extensively utilized to map the structure and dynamics of large-scale functional network organization in humans. In addition to

Brain Function in Children with Obstructive Sleep Apnea: A Resting-State fMRI Study.

open access: yesSleep, 2021
OBJECTIVE To explore the neural difference between children with obstructive sleep apnea (OSA) and healthy controls, together with the relation between this difference and cognitive dysfunction of children with OSA.

Resting State fMRI: Going Through the Motions [PDF]

open access: yesFrontiers in Neuroscience, 2019
Resting state functional magnetic resonance imaging (rs-fMRI) has become an indispensable tool in neuroscience research. Despite this, rs-fMRI signals are easily contaminated by artifacts arising from movement of the head during data collection. The artifacts can be problematic even for motions on the millimeter scale, with complex spatiotemporal ...

Resting-State fMRI: A Review of Methods and Clinical Applications

open access: yesAmerican Journal of Neuroradiology, 2013
SUMMARY: Resting-state fMRI measures spontaneous low-frequency fluctuations in the BOLD signal to investigate the functional architecture of the brain.

Multiscale network activity in resting state fMRI [PDF]

open access: yes2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
The brain is inherently multiscalar in both space and time. We argue that this multiscalar nature is reflected in the blood oxygenation level dependent (BOLD) fluctuations used to map functional connectivity. We present evidence that global fluctuations in activity, quasiperiodic spatiotemporal patterns, and aperiodic time-varying activity coexist ...

Visual learning induces changes in resting-state fMRI multivariate pattern of information [PDF]

open access: yes, 2015
When measured with functional magnetic resonance imaging (fMRI) in the resting state (R-fMRI), spontaneous activity is correlated between brain regions that are anatomically and functionally related. Learning and/or task performance can induce modulation
