Macroscopic cortical dynamics: Spatially uncorrelated but temporally coherent rich-club organisations in source-space resting-state EEG [PDF]

open access: yesarXiv, 2020
Synchronous oscillations of neuronal populations support resting-state cortical activity. Recent studies indicate that resting-state functional connectivity is not static, but exhibits complex dynamics. The mechanisms underlying the complex dynamics of cortical activity have not been well characterised.

Dynamic reconfiguration of the default mode network during narrative comprehension

open access: yesNature Communications, 2016
Does the default mode network (DMN) reconfigure to encode information about the changing environment? This question has proven difficult, because patterns of functional connectivity reflect a mixture of stimulus-induced neural processes, intrinsic neural

Resting-state networks associated with cognitive processing show more age-related decline than those associated with emotional processing [PDF]

open access: yes, 2017
Correlations in activity across disparate brain regions during rest reveal functional networks in the brain. Although previous studies largely agree that there is an age-related decline in the “default mode network,” how age affects other resting-state ...

Brain default-mode network dysfunction in addiction

open access: yesNeuroImage, 2019
Aberrant patterns of brain functional connectivity in the default mode network (DMN) have been observed across different classes of substance use disorder (SUD) and are associated with craving and relapse. In addicted individuals resting functional connectivity (RSFC) of the anterior DMN, which participates in attribution of personal value and ...

The Default Mode Network in Healthy Aging and Alzheimer′s Disease [PDF]

open access: yesInternational Journal of Alzheimer’s Disease, 2011
In the past decade, a “default mode network” (DMN) has been highlighted in neuroimaging studies as a set of brain regions showing increased activity in task‐free state compared to cognitively demanding task, and synchronized activity at rest. Changes within this network have been described in healthy aging as well as in Alzheimer′s disease (AD) and ...

Pickering Emulsion for Enhanced Viability of Plant Growth Promoting Bacteria and Combined Delivery of Agrochemicals and Biologics

open access: yesAdvanced Functional Materials, EarlyView.
Cellulosic emulsions as multi‐cargo agriculture formulations. Pickering emulsions stabilized by cellulose acetate particles provide an effective platform for delivering a range of agricultural cargoes, including plant growth‐promoting bacteria and agrochemicals.

Functional brain modules reconfigure at multiple scales across the human lifespan [PDF]

open access: yesarXiv, 2015
The human brain is a complex network of interconnected brain regions organized into functional modules with distinct roles in cognition and behavior. An important question concerns the persistence and stability of these modules over the human lifespan.

Using Network Interbank Contagion in Bank Default Prediction [PDF]

open access: yesarXiv, 2020
Interbank contagion can theoretically exacerbate losses in a financial system and lead to additional cascade defaults during downturn. In this paper we produce default analysis using both regression and neural network models to verify whether interbank contagion offers any predictive explanatory power on default events.

Localizing and Assessing Node Significance in Default Mode Network using Sub-Community Detection in Mild Cognitive Impairment [PDF]

open access: yesarXiv, 2023
Our study aims to utilize fMRI to identify the affected brain regions within the Default Mode Network (DMN) in subjects with Mild Cognitive Impairment (MCI), using a novel Node Significance Score (NSS). We construct subject-specific DMN graphs by employing partial correlation of Regions of Interest (ROIs) that make-up the DMN.

Hemodynamic Correlates of Electrophysiological Activity in the Default Mode Network [PDF]

open access: yesFrontiers in Neuroscience, 2019
Hemodynamic fluctuations in the default mode network (DMN), observed through functional magnetic resonance imaging (fMRI), have been linked to electrophysiological oscillations detected by electroencephalography (EEG). It has been reported that, among the electrophysiological oscillations, those in the alpha frequency range (8-13 Hz) are the most ...
