Nonlinear changes in delayed functional network topology in Alzheimer’s disease: relationship with amyloid and tau pathology

Alzheimer’s Research & Therapy, 2023
Background Alzheimer’s disease is a neurodegenerative disorder associated with the abnormal deposition of pathological processes, such as amyloid-ß and tau, which produces nonlinear changes in the functional connectivity patterns between different brain ...

On connected Boolean functions

Discrete Applied Mathematics, 1999
Various classes of Boolean functions are introduced: connected, strongly connected, geodetic, convex, strongly convex and concordant. They are characterized by some properties of the subgraph of the Boolean hypercube induced by the (false) true points of a function.

Cerebrovascular disease influences functional and structural network connectivity in patients with amnestic mild cognitive impairment and Alzheimer’s disease

Alzheimer’s Research & Therapy, 2018
Background Patients with amnestic mild cognitive impairment (aMCI) and Alzheimer’s disease (AD) show functional and structural connectivity alterations in the default mode network (DMN) while cerebrovascular disease (CeVD) shows functional and structural

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 ...

Pattern classification of large-scale functional brain networks : identification of informative neuroimaging markers for epilepsy [PDF]

, 2012
The accurate prediction of general neuropsychiatric disorders, on an individual basis, using resting-state functional magnetic resonance imaging (fMRI) is a challenging task of great clinical significance.

Vascular risk factors are associated with a decline in resting-state functional connectivity in cognitively unimpaired individuals at risk for Alzheimer's disease

NeuroImage, 2021
Resting-state functional connectivity is suggested to be cross-sectionally associated with both vascular burden and Alzheimer's disease (AD) pathology. However, evidence is lacking regarding longitudinal changes in functional connectivity.

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

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

A reversal coarse-grained analysis with application to an altered functional circuit in depression [PDF]

, 2013
Introduction: When studying brain function using functional magnetic resonance imaging (fMRI) data containing tens of thousands of voxels, a coarse-grained approach – dividing the whole brain into regions of interest – is applied frequently to ...
