Insula Functional Connectivity in Schizophrenia [PDF]

Schizophrenia Research, 2019
AbstractThe insula is structurally abnormal in schizophrenia, demonstrating robust reductions in gray matter volume, cortical thickness, and altered gyrification during prodromal, early and chronic stages of the illness. Despite compelling structural alterations, less is known about its functional connectivity, limited by studies considering the insula

Functional connectivity patterns in parosmia

Behavioral and Brain Functions, 2023
Abstract Objective Parosmia is a qualitative olfactory dysfunction presenting as “distorted odor perception” in presence of an odor source. Aim of this study was to use resting state functional connectivity to gain more information on the alteration of olfactory processing at the level of the central nervous system level.

Reproducibility of EEG functional connectivity in Alzheimer’s disease

Alzheimer's Research & Therapy, 2020
Background Although numerous electroencephalogram (EEG) studies have described differences in functional connectivity in Alzheimer’s disease (AD) compared to healthy subjects, there is no general consensus on the methodology of estimating functional ...

Compositions of continuous functions and connected functions [PDF]

Proceedings of the American Mathematical Society, 1992
Suppose f : X → Y f:X \to Y is continuous and onto and g : Y → Z g:Y \to Z is such that g ∘ f : X → Z g \circ f:X \to Z has a property we are interested in. For which properties of

Reduced default mode network functional connectivity in patients with recurrent major depressive disorder

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Functional connectivity within the default mode network in patients with major depressive disorder has been frequently reported to be abnormal but with contradicting directions in previous studies with small sample sizes.

Rethinking Measures of Functional Connectivity via Feature Extraction

Scientific Reports, 2020
Functional magnetic resonance imaging (fMRI)-based functional connectivity (FC) commonly characterizes the functional connections in the brain. Conventional quantification of FC by Pearson's correlation captures linear, time-domain dependencies among ...

The effect of the GLP-1 analogue Exenatide on functional connectivity within an NTS-based network in women with and without obesity. [PDF]

, 2017
ObjectiveThe differential effect of GLP-1 agonist Exenatide on functional connectivity of the nucleus tractus solitaries (NTS), a key region associated with homeostasis, and on appetite-related behaviours was investigated in women with normal weight ...

Connectivity of submodular functions

Discrete Mathematics, 1992
AbstractThe notion of connectivity for submodular functions was introduced by Cunningham. This paper relates the connectivity of such a function f to that of certain submodular functions which are derived from f. In particular, we prove a generalisation of the well-known matroid result that, for every element x of a connected matroid M, either the ...

Dynamic Functional Connectivity

, 2023
Most generally, dynamic functional connectivity (FC) refers to the non-instantaneous couplings across timeseries from a set of brain areas, here as measured by fMRI. This is in contrast to static FC, which is defined as purely instantaneous relations. In this chapter, we provide a hands-on description of a non-exhaustive selection of different methods ...

Large-Scale Network Dysfunction in Major Depressive Disorder: A Meta-analysis of Resting-State Functional Connectivity.

JAMA psychiatry, 2015
IMPORTANCE Major depressive disorder (MDD) has been linked to imbalanced communication among large-scale brain networks, as reflected by abnormal resting-state functional connectivity (rsFC).
