Reliability modelling of resting-state functional connectivity

open access: yesNeuroImage, 2021
Resting-state functional magnetic resonance imaging (rs-fMRI) has an inherently low signal-to-noise ratio largely due to thermal and physiological noise that attenuates the functional connectivity (FC) estimates.

Aging relates to a disproportionately weaker functional architecture of brain networks during rest and task states

open access: yesNeuroImage, 2020
Functional connectivity – the co-activation of brain regions – forms the basis of the brain’s functional architecture. Often measured during resting-state (i.e., in a task-free setting), patterns of functional connectivity within and between brain ...

Resting-State Functional Connectivity in Mathematical Expertise

open access: yesBrain Sciences, 2021
To what extent are different levels of expertise reflected in the functional connectivity of the brain? We addressed this question by using resting-state functional magnetic resonance imaging (fMRI) in mathematicians versus non-mathematicians.

Large-scale intrinsic connectivity is consistent across varying task demands.

open access: yesPLoS ONE, 2019
Measuring whole-brain functional connectivity patterns based on task-free ('resting-state') spontaneous fluctuations in the functional MRI (fMRI) signal is a standard approach to probing habitual brain states, independent of task-specific context.

Functional connectivity in the brain estimated by analysis of gamma events. [PDF]

open access: yesPLoS ONE, 2014
It is known that gamma activity is generated by local networks. In this paper we introduced a new approach for estimation of functional connectivity between neuronal networks by measuring temporal relations between peaks of gamma event amplitudes.

Clinical applications of resting state functional connectivity

open access: yesFrontiers in Systems Neuroscience, 2010
During resting conditions the brain remains functionally and metabolically active. One manifestation of this activity that has become an important research tool is spontaneous fluctuations in the blood oxygen level dependent (BOLD) signal of fMRI.

Resting state functional connectivity predicts neurofeedback response

open access: yesFrontiers in Behavioral Neuroscience, 2014
Tailoring treatments to the specific needs and biology of individual patients – personalized medicine – requires delineation of reliable predictors of response. Unfortunately, these have been slow to emerge, especially in neuropsychiatric disorders.

Modulation of brain resting-state networks by sad mood induction. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: There is growing interest in the nature of slow variations of the blood oxygen level-dependent (BOLD) signal observed in functional MRI resting-state studies.

Disruption of brain connectivity in acute stroke patients with early impairment in consciousness

open access: yesFrontiers in Psychology, 2014
Impairment in consciousness is common in acute stroke patients and is correlated with the clinical outcome after stroke. The underlying mechanism is not completely understood, with little known about brain activity and connectivity changes in acute ...
