Structural network efficiency is associated with cognitive impairment in small-vessel disease. [PDF]

, 2014
To characterize brain network connectivity impairment in cerebral small-vessel disease (SVD) and its relationship with MRI disease markers and cognitive impairment.METHODS: A cross-sectional design applied graph-based efficiency analysis to deterministic

Functional and structural connectivity of the amygdala in obsessive-compulsive disorder

NeuroImage: Clinical, 2017
Background: The amygdala is known to be involved in anxiety processing, but its role in the psychopathology of obsessive-compulsive disorder (OCD) is still unclear.

Neural complexity and structural connectivity [PDF]

Physical Review E, 2009
Tononi [Proc. Natl. Acad. Sci. U.S.A. 91, 5033 (1994)] proposed a measure of neural complexity based on mutual information between complementary subsystems of a given neural network, which has attracted much interest in the neuroscience community and beyond.

Network-level macroscale structural connectivity predicts propagation of transcranial magnetic stimulation

NeuroImage, 2020
Information processing in the brain is mediated by structural white matter pathways and is highly dependent on topological brain properties. Here we combined transcranial magnetic stimulation (TMS) with high-density electroencephalography (EEG) and ...

Volumetric and structural connectivity abnormalities co-localise in TLE

NeuroImage: Clinical, 2022
Patients with temporal lobe epilepsy (TLE) exhibit both volumetric and structural connectivity abnormalities relative to healthy controls. How these abnormalities inter-relate and their mechanisms are unclear.

Mapping Structural Connectivity Using Diffusion MRI: Challenges and Opportunities

Journal of Magnetic Resonance Imaging, 2020
Diffusion MRI‐based tractography is the most commonly‐used technique when inferring the structural brain connectome, i.e., the comprehensive map of the connections in the brain.

Aerobic Exercise Induces Functional and Structural Reorganization of CNS Networks in Multiple Sclerosis: A Randomized Controlled Trial

Frontiers in Human Neuroscience, 2020
Objectives: Evidence from animal studies suggests that aerobic exercise may promote neuroplasticity and could, therefore, provide therapeutic benefits for neurological diseases such as multiple sclerosis (MS).

Multigroup connectivity structures and their implications [PDF]

Network Science, 2019
AbstractWe investigate the implications of different forms of multigroup connectivity. Four multigroup connectivity modalities are considered: co-memberships, edge bundles, bridges, and liaison hierarchies. We propose generative models to generate these four modalities. Our models are variants of planted partition or stochastic block models conditioned

Preterm birth leads to impaired rich-club organization and fronto-paralimbic/limbic structural connectivity in newborns

NeuroImage, 2020
Prematurity disrupts brain development during a critical period of brain growth and organization and is known to be associated with an increased risk of neurodevelopmental impairments.
