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

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

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 ...

Functional Connectivity of the Posteromedial Cortex
PLoS ONE, 2010 As different areas within the PMC have different connectivity patterns with various cortical and subcortical regions, we hypothesized that distinct functional modules may be present within the PMC. Because the PMC appears to be the most active region during resting state, it has been postulated to play a fundamental role in the control of baseline ...

Strengthening Connections: Functional Connectivity and Brain Plasticity [PDF]
Neuropsychology Review, 2014 The ascendancy of functional neuroimaging has facilitated the addition of network-based approaches to the neuropsychologist's toolbox for evaluating the sequelae of brain insult. In particular, intrinsic functional connectivity (iFC) mapping of resting state fMRI (R-fMRI) data constitutes an ideal approach to measuring macro-scale networks in the human

Functional Connectivity of the Chemosenses: A Review
Frontiers in Systems Neuroscience, 2022 Functional connectivity approaches have long been used in cognitive neuroscience to establish pathways of communication between and among brain regions. However, the use of these analyses to better understand how the brain processes chemosensory information remains nascent.

Mapping functional connectivity
Ecological Indicators, 2009 An objective and reliable assessment of wildlife movement is important in theoretical and applied ecology. The identification and mapping of landscape elements that may enhance functional connectivity is usually a subjective process based on visual interpretations of species movement patterns.

Disambiguating brain functional connectivity
NeuroImage, 2018 Functional connectivity (FC) analyses of correlations of neural activity are used extensively in neuroimaging and electrophysiology to gain insights into neural interactions. However, analyses assessing changes in correlation fail to distinguish effects produced by sources as different as changes in neural signal amplitudes or noise levels.
