More than just statics: Static and temporal dynamic changes in intrinsic brain activity in unilateral temporal lobe epilepsy

Frontiers in Human Neuroscience, 2022
BackgroundTemporal lobe epilepsy (TLE) is the most prevalent refractory focal epilepsy and is more likely accompanied by cognitive impairment. The fully understanding of the neuronal activity underlying TLE is of great significance.ObjectiveThis study ...

High-resolution mapping of substantia nigra in Parkinson’s disease using 7 tesla magnetic resonance imaging

npj Parkinson's Disease
Parkinson’s disease causes a progressive loss of dopaminergic neurons and iron accumulation in the substantia nigra pars compacta. Using ultra-high field magnetic resonance imaging (MRI) at 7 tesla in 43 Parkinson’s patients and 24 healthy controls, we ...

A clinical-radiomics combined model based on carotid atherosclerotic plaque for prediction of ischemic stroke

Frontiers in Neurology
ObjectivesTo accurately predict the risk of ischemic stroke, we established a radiomics model of carotid atherosclerotic plaque-based high-resolution vessel wall magnetic resonance imaging (HR-VWMRI) and combined it with clinical indicators.Materials and

Thalamocortical Connectivity and Microstructural Changes in Congenital and Late Blindness

Neural Plasticity, 2017
There is ample evidence that the occipital cortex of congenitally blind individuals processes nonvisual information. It remains a debate whether the cross-modal activation of the occipital cortex is mediated through the modulation of preexisting ...

Theta Activity in the Left Dorsal Premotor Cortex During Action Re-Evaluation and Motor Reprogramming

Frontiers in Human Neuroscience, 2018
The ability to rapidly adjust our actions to changes in the environment is a key function of human motor control. Previous work implicated the dorsal premotor cortex (dPMC) in the up-dating of action plans based on environmental cues.

Functional nanoparticles for magnetic resonance imaging

WIREs Nanomedicine and Nanobiotechnology, 2016
Nanoparticle‐based magnetic resonance imaging (MRI) contrast agents have received much attention over the past decade. By virtue of a high payload of magnetic moieties, enhanced accumulation at disease sites, and a large surface area for additional modification with targeting ligands, nanoparticle‐based contrast agents offer promising new platforms to ...
