MGH–USC Human Connectome Project datasets with ultra-high b-value diffusion MRI [PDF]

NeuroImage, 2016
The MGH-USC CONNECTOM MRI scanner housed at the Massachusetts General Hospital (MGH) is a major hardware innovation of the Human Connectome Project (HCP). The 3T CONNECTOM scanner is capable of producing a magnetic field gradient of up to 300 mT/m strength for in vivo human brain imaging, which greatly shortens the time spent on diffusion encoding, and

Preoperative Functional Connectivity Predicts Antiparkinson Drug Change after Deep Brain Stimulation

Movement Disorders, EarlyView.
Abstract Background Deep brain stimulation (DBS) can effectively ameliorate motor symptoms in Parkinson's disease (PD), but patient outcomes remain variable. Clinical predictors lack reliability and only explain a small proportion of outcome variance, outlining a need for biomarkers that can enhance prediction accuracy.

Human Connectome Project (Hcp)

, 2016
This project deals with the nervous system and its function in brain. Here connectome means the microscopic neural connectivity and its mapping between all the neurons present in the brain which further represents their graphical representation on the visual screen also which will further help us to zoom into a region to explore the cells and the ...

Task-related edge density (TED) - a new method for revealing large-scale network formation in fMRI data of the human brain

, 2015
The formation of transient networks in response to external stimuli or as a reflection of internal cognitive processes is a hallmark of human brain function. However, its identification in fMRI data of the human brain is notoriously difficult.

Functional Connectivity to the Cerebellum and Resting‐State Networks Predict Earlier Improvement of Dystonia Following Globus Pallidus Internus‐Deep Brain Stimulation (GPi‐DBS)

Movement Disorders, EarlyView.
Early improvement of dystonia after globus pallidus internus‐deep brain stimulation (GPi‐DBS) is associated with stimulation of the globus pallidus externus‐subthalamic nucleus (GPe‐STN) fibers and the lenticular fasciculus. Functional connectivity to the cerebellar cortex and the limbic and default mode networks predict early improvement of symptoms ...

Recreational marijuana use impacts white matter integrity and subcortical (but not cortical) morphometry

NeuroImage: Clinical, 2016
A recent shift in legal and social attitudes toward marijuana use has also spawned a surge of interest in understanding the effects of marijuana use on the brain. There is considerable evidence that an adolescent onset of marijuana use negatively impacts

The Advantage is at the Ladies: Brain Size Bias-Compensated Graph-Theoretical Parameters are Also Better in Women's Connectomes [PDF]

, 2015
In our previous study we have shown that the female connectomes have significantly better, deep graph-theoretical parameters, related to superior "connectivity", than the connectome of the males. Since the average female brain is smaller than the average

Info-Clustering: A Mathematical Theory for Data Clustering

, 2016
We formulate an info-clustering paradigm based on a multivariate information measure, called multivariate mutual information, that naturally extends Shannon's mutual information between two random variables to the multivariate case involving more than ...

Monoaminergic Networks of Cognitive and Behavioral Symptoms in Early Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is associated with several behavioral and cognitive symptoms, the neurobiological background of which is not yet fully understood. Objectives The aim was to investigate the association between monoamine function and four specific nonmotor symptoms in early PD using the Parkinson's Progression Markers ...

The adverse effect of gradient nonlinearities on diffusion MRI: From voxels to group studies

NeuroImage, 2020
Nonlinearities of gradient magnetic fields in diffusion MRI (dMRI) can introduce systematic errors in estimates of diffusion measures. While there are correction methods that can compensate for these errors, as presented in the Human Connectome Project ...
