Enhanced temporal variability of amygdala-frontal functional connectivity in patients with schizophrenia

NeuroImage: Clinical, 2018
Background: The “dysconnectivity hypothesis” was proposed 20 years ago. It characterized schizophrenia as a disorder with dysfunctional connectivity across a large range of distributed brain areas.

Altered intrinsic functional connectivity in language-related brain regions in association with verbal memory performance in euthymic bipolar patients [PDF]

, 2013
Potential abnormalities in the structure and function of the temporal lobes have been studied much less in bipolar disorder than in schizophrenia. This may not be justified because language-related symptoms, such as pressured speech and flight of ideas ...

Resting State fMRI Reveals Diminished Functional Connectivity in a Mouse Model of Amyloidosis [PDF]

, 2013
Introduction: Functional connectivity (FC) studies have gained immense popularity in the evaluation of several neurological disorders, such as Alzheimer’s disease (AD). AD is a complex disorder, characterised by several pathological features. The problem

Differentiating the functional contributions of resting connectivity networks to memory decision-making : fMRI support for multi-stage control processes [PDF]

, 2015
Neural substrates of memory control are engaged when participants encounter unexpected mnemonic stimuli (e.g., a new word when told to expect an old word).

Neural activation and functional connectivity during motor imagery of bimanual everyday actions [PDF]

, 2012
Bimanual actions impose intermanual coordination demands not present during unimanual actions. We investigated the functional neuroanatomical correlates of these coordination demands in motor imagery (MI) of everyday actions using functional magnetic ...

Changes in functional connectivity within the rat striatopallidal axis during global brain activation in vivo [PDF]

, 2006
The functional organization of the basal ganglia (BG) is often defined according to one of two opposing schemes. The first proposes multiple, essentially independent channels of information processing.

Physiological and motion signatures in static and time-varying functional connectivity and their subject identifiability

eLife, 2021
Human brain connectivity yields significant potential as a noninvasive biomarker. Several studies have used fMRI-based connectivity fingerprinting to characterize individual patterns of brain activity. However, it is not clear whether these patterns mainly reflect neural activity or the effect of physiological and motion processes.

Quasi-periodic patterns of brain activity in individuals with attention-deficit/hyperactivity disorder

NeuroImage: Clinical, 2019
Individuals with attention-deficit/hyperactivity disorder have disrupted functional connectivity in the default mode and task positive networks. Traditional fMRI analysis techniques that focus on ‘static’ changes in functional connectivity have been ...

The integrative functional connectivity analysis between seafarer’s brain networks using functional magnetic resonance imaging data of different states

Frontiers in Neuroscience, 2022
The particularity of seafarers’ occupation makes their brain functional activities vulnerable to the influence of working environments, which leads to abnormal functional connectivities (FCs) between brain networks.

Neuroplastic changes in resting-state functional connectivity after stroke rehabilitation

, 2017
Most neuroimaging research in stroke rehabilitation mainly focuses on the neural mechanisms underlying the natural history of post-stroke recovery. However, connectivity mapping from resting-state fMRI is well suited for different neurological conditions
