Resting states are resting traits--an FMRI study of sex differences and menstrual cycle effects in resting state cognitive control networks. [PDF]

open access: yesPLoS ONE, 2014
To what degree resting state fMRI is stable or susceptible to internal mind states of the individual is currently an issue of debate. To address this issue, the present study focuses on sex differences and investigates whether resting state fMRI is ...

A comparison of resting state functional magnetic resonance imaging to invasive electrocortical stimulation for sensorimotor mapping in pediatric patients [PDF]

open access: yesNeuroImage: Clinical, 2019
Localizing neurologic function within the brain remains a significant challenge in clinical neurosurgery. Invasive mapping with direct electrocortical stimulation currently is the clinical gold standard but is impractical in young or cognitively delayed ...

Caffeine-Induced Global Reductions in Resting-state BOLD Connectivity reflect Widespread Decreases in MEG Connectivity [PDF]

open access: yesFrontiers in Human Neuroscience, 2013
In resting-state functional magnetic resonance imaging (fMRI), the temporal correlation between spontaneous fluctuations of the blood oxygenation level dependent (BOLD) signal from different brain regions is used to assess functional connectivity ...

Resting state network connectivity is attenuated by fMRI acoustic noise

open access: yesNeuroImage, 2022
Introduction: During the past decades there has been an increasing interest in tracking brain network fluctuations in health and disease by means of resting state functional magnetic resonance imaging (rs-fMRI). Rs-fMRI however does not provide the ideal

Neural representations of self-generated thought during think-aloud fMRI

open access: yesNeuroImage, 2023
Is the brain at rest during the so-called resting state? Ongoing experiences in the resting state vary in unobserved and uncontrolled ways across time, individuals, and populations.

Resting-state brain activity can predict target-independent aptitude in fMRI-neurofeedback training

open access: yesNeuroImage, 2021
Neurofeedback (NF) aptitude, which refers to an individual's ability to change brain activity through NF training, has been reported to vary significantly from person to person.

An approach for identifying brainstem dopaminergic pathways using resting state functional MRI. [PDF]

open access: yes, 2014
Here, we present an approach for identifying brainstem dopaminergic pathways using resting state functional MRI. In a group of healthy individuals, we searched for significant functional connectivity between dopamine-rich midbrain areas (substantia nigra;

Propagated infra-slow intrinsic brain activity reorganizes across wake and slow wave sleep [PDF]

open access: yes, 2015
Propagation of slow intrinsic brain activity has been widely observed in electrophysiogical studies of slow wave sleep (SWS). However, in human resting state fMRI (rs-fMRI), intrinsic activity has been understood predominantly in terms of zero-lag ...

Resting-state fMRI signals contain spectral signatures of local hemodynamic response timing

open access: yeseLife, 2023
Functional magnetic resonance imaging (fMRI) has proven to be a powerful tool for noninvasively measuring human brain activity; yet, thus far, fMRI has been relatively limited in its temporal resolution.

FMRI resting slow fluctuations correlate with the activity of fast cortico-cortical physiological connections. [PDF]

open access: yesPLoS ONE, 2012
Recording of slow spontaneous fluctuations at rest using functional magnetic resonance imaging (fMRI) allows distinct long-range cortical networks to be identified.
