Increased structural connectivity in high schizotypy [PDF]

, 2023
The link between brain structural connectivity and schizotypy was explored in two healthy participant cohorts, collected at two different neuroimaging centres, comprising 140 and 115 participants, respectively.

The structural connectivity mapping of the intralaminar thalamic nuclei

Scientific Reports, 2023
The intralaminar nuclei of the thalamus play a pivotal role in awareness, conscious experience, arousal, sleep, vigilance, as well as in cognitive, sensory, and sexual processing.

Insomnia subtypes have differentiating deviations in brain structural connectivity

bioRxiv, 2023
Objective Insomnia disorder is the most common sleep disorder. A better understanding of insomnia-related deviations in the brain could inspire better treatment.

Structured Connectivity Augmentation [PDF]

SIAM Journal on Discrete Mathematics, 2018
We initiate the algorithmic study of the following "structured augmentation" question: is it possible to increase the connectivity of a given graph G by superposing it with another given graph H? More precisely, graph F is the superposition of G and H with respect to injective mapping ϕ: V(H)->V(G) if every edge uv of F is either an edge of G, or ϕ^{

A Mutual Multi-Scale Triplet Graph Convolutional Network for Classification of Brain Disorders Using Functional or Structural Connectivity

IEEE Transactions on Medical Imaging, 2021
Brain connectivity alterations associated with mental disorders have been widely reported in both functional MRI (fMRI) and diffusion MRI (dMRI). However, extracting useful information from the vast amount of information afforded by brain networks ...

Cortical Surfaces Integration with Tractography for Structural Connectivity Analysis.

, 2021
Background: Mapping diffusion MRI tractography streamlines to the cortical surface facilitates the integration of white matter features onto gray matter, especially for connectivity analysis. Method: In this work, we present methods that combine cortical

Human brain structural connectivity matrices–ready for modelling

Scientific Data, 2022
The human brain represents a complex computational system, the function and structure of which may be measured using various neuroimaging techniques focusing on separate properties of the brain tissue and activity.

Multiscale gradients of corticopontine structural connectivity. [PDF]

Sci Rep
The cerebellum’s involvement in a range of cognitive, emotional, and motor processes has become increasingly evident. Given the uniformity of the cerebellar cortex’s cellular architecture its contributions to varied processes are thought be partially ...

An integrated resource for functional and structural connectivity of the marmoset brain

Nature Communications, 2022
Comprehensive integration of structural and functional connectivity data is required to model brain functions accurately. While resources for studying the structural connectivity of non-human primate brains already exist, their integration with ...

A structural connectivity atlas of limbic brainstem nuclei

bioRxiv, 2022
Background Understanding the structural connectivity of key brainstem nuclei with limbic cortical regions is essential to the development of therapeutic neuromodulation for depression, chronic pain, addiction, anxiety and movement disorders.
