Functional connectivity in the resting brain: A network analysis of the default mode hypothesis
Proceedings of the National Academy of Sciences of the United States of America, 2002 Functional imaging studies have shown that certain brain regions, including posterior cingulate cortex (PCC) and ventral anterior cingulate cortex (vACC), consistently show greater activity during resting states than during cognitive tasks.

Frontiers in Neuroanatomy, 2018 The heterogeneity and complexity of white matter (WM) pathways of the human brain were discretely described by pioneers such as Willis, Stenon, Malpighi, Vieussens and Vicq d’Azyr up to the beginning of the 19th century. Subsequently, novel approaches to

State-dependent changes of connectivity patterns and functional brain network topology in Autism Spectrum Disorder [PDF]
, 2012 Anatomical and functional brain studies have converged to the hypothesis that Autism Spectrum Disorders (ASD) are associated with atypical connectivity.

Structural Brain Connectivity Constrains within-a-Day Variability of Direct Functional Connectivity
Frontiers in Human Neuroscience, 2017 The idea that structural white matter connectivity constrains functional connectivity (interactions among brain regions) has widely been explored in studies of brain networks; studies have mostly focused on the “average” strength of functional ...

Independent contributions of structural and functional connectivity: Evidence from a stroke model
Network Neuroscience, 2021 Altered functional connectivity is related to severity of language impairment in poststroke aphasia. However, it is not clear whether this finding specifically reflects loss of functional coherence, or more generally, is related to decreased structural ...

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 This paper relates the connectivity of submodular functions \(f\) to that of certain submodular functions which are derived from \(f\). Here the function \(f\) on \(S\) is submodular if \(f(A)+f(B)\geq f(A\cup B)+f(A\cap B)\) for all subsets \(A\) and \(B\) of \(S\).

Regularized Functional Connectivity in Schizophrenia
Frontiers in Human Neuroscience, 2022 Regularization may be used as an alternative to dimensionality reduction when the number of variables in a model is much larger than the number of available observations. In a recent study from our group regularized regression was employed to quantify brain functional connectivity in a sample of healthy controls using a brain parcellation and resting ...

Frontiers in Neuroscience, 2021 Major depressive disorder (MDD) is a severe mental disorder and is lacking in biomarkers for clinical diagnosis. Previous studies have demonstrated that functional abnormalities of the unifying triple networks are the underlying basis of the ...
