The electrophysiological basis of resting-state fMRI hyperconnectivity in early Alzheimer’s disease [PDF]

open access: yesAlzheimer’s Research & Therapy
Objective One of the most intriguing findings in Alzheimer’s disease connectivity studies is resting-state fMRI hyperconnectivity in the preclinical and prodromal phase.

An information-theoretic analysis of resting-state versus task fMRI [PDF]

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.

Resting State fMRI: Going Through the Motions

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.

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 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 ...

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.

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.

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.

Searching multiregression dynamic models of resting-state fMRI networks using integer programming [PDF]

open access: yes, 2015
A Multiregression Dynamic Model (MDM) is a class of multivariate time series that represents various dynamic causal processes in a graphical way. One of the advantages of this class is that, in contrast to many other Dynamic Bayesian Networks, the ...
