Topography of functional connectivity in human multichannel EEG during second language processing [PDF]
We analyze the topography of nonlinear interdependence in the EEG of two group German-native speakers, divided according to their English proficiency level (high or low), when listening to one text in German and one in English.

Nonequilibrium Green’s Functions for Functional Connectivity in the Brain [PDF]
Physical Review Letters, 2021 A theoretical framework describing the set of interactions between neurons in the brain, or functional connectivity, should include dynamical functions representing the propagation of signal from one neuron to another. Green's functions and response functions are natural candidates for this but, while they are conceptually very useful, they are usually

Dynamic BOLD functional connectivity in humans and its electrophysiological correlates [PDF]
, 2012 Neural oscillations subserve many human perceptual and cognitive operations. Accordingly, brain functional connectivity is not static in time, but fluctuates dynamically following the synchronization and desynchronization of neural populations.

Task Residual Functional Connectivity in Language and Attention Networks [PDF]
, 2018 The present study compared network specificity between task-residual and resting state data types. Task-residual data capitalizes on the remaining variance after the mean task-related signal is removed from the time series.

Connectivity functions and polymatroids
Advances in Applied Mathematics, 2016 A {\em connectivity function on} a set $E$ is a function $λ:2^E\rightarrow \mathbb R$ such that $λ(\emptyset)=0$, that $λ(X)=λ(E-X)$ for all $X\subseteq E$ and that $λ(X\cap Y)+λ(X\cup Y)\leq λ(X)+λ(Y)$ for all $X,Y \subseteq E$. Graphs, matroids and, more generally, polymatroids have associated connectivity functions.

Functional Connectivity in Aging [PDF]
, 2019 A large body of research shows that aging is accompanied by localized changes in brain structure and function. However, over the past decade the neuroimaging community has begun to recognize the importance of investigating the brain as a network.

Functional connectivity during a social emotion task in adolescents and in adults [PDF]
, 2009 In this fMRI study we investigated functional connectivity between components of the mentalising system during a social emotion task, using psychophysiological interaction (PPI) analysis.

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
