A mechanistic model of connector hubs, modularity, and cognition

, 2018
The human brain network is modular--comprised of communities of tightly interconnected nodes. This network contains local hubs, which have many connections within their own communities, and connector hubs, which have connections diversely distributed ...

Changes in structural network topology correlate with severity of hallucinatory behavior in Parkinson's disease [PDF]

, 2019
Inefficient integration between bottom-up visual input and higher order visual processing regions is implicated in visual hallucinations in Parkinson's disease (PD). Here, we investigated white matter contributions to this perceptual imbalance hypothesis.

High-accuracy individual identification using a “thin slice” of the functional connectome [PDF]

Network Neuroscience, 2019
Connectome fingerprinting—a method that uses many thousands of functional connections in aggregate to identify individuals—holds promise for individualized neuroimaging.

Mapping the subcortical connectome using in vivo diffusion MRI: Feasibility and reliability

NeuroImage, 2022
Tractography combined with regions of interest (ROIs) has been used to non-invasively study the structural connectivity of the cortex as well as to assess the reliability of these connections.

A large normative connectome for exploring the tractographic correlates of focal brain interventions

Scientific Data
Diffusion-weighted MRI (dMRI) is a widely used neuroimaging modality that permits the in vivo exploration of white matter connections in the human brain.

The Superior Fronto-Occipital Fasciculus in the Human Brain Revealed by Diffusion Spectrum Imaging Tractography: An Anatomical Reality or a Methodological Artifact?

Frontiers in Neuroanatomy, 2017
The existence of the superior fronto-occipital fasciculus (SFOF) in the human brain remains controversial. The aim of the present study was to clarify the existence, course, and terminations of the SFOF.

Connectome 2.0: Developing the next-generation ultra-high gradient strength human MRI scanner for bridging studies of the micro-, meso- and macro-connectome

NeuroImage, 2021
The first phase of the Human Connectome Project pioneered advances in MRI technology for mapping the macroscopic structural connections of the living human brain through the engineering of a whole-body human MRI scanner equipped with maximum gradient ...

Simultaneous Matrix Diagonalization for Structural Brain Networks Classification

, 2017
This paper considers the problem of brain disease classification based on connectome data. A connectome is a network representation of a human brain. The typical connectome classification problem is very challenging because of the small sample size and ...
