Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

open access: yesMovement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

Electroencephalography‐Based Clustering Reveals Robust Neurophysiological Subtypes in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is clinically heterogeneous, with substantial variability in motor and cognitive features. Conventional clinical scales provide limited insight into underlying neural mechanisms and show poor longitudinal stability.

Altered spontaneous brain activity in chronic smokers revealed by fractional ramplitude of low-frequency fluctuation analysis: a preliminary study

open access: yesScientific Reports, 2017
Although a substantial body of previous functional magnetic resonance imaging (fMRI) studies have revealed different brain responses to external stimuli in chronic cigarette smokers compared with nonsmokers, only a few studies assessed brain spontaneous ...

A spatially constrained low-rank matrix factorization for the functional parcellation of the brain

open access: yes, 2014
We propose a new matrix recovery framework to partition brain activity using time series of resting-state functional Magnetic Resonance Imaging (fMRI). Spatial clusters are obtained with a new low-rank factorization algorithm that offers the ability to ...

Transcranial Pulse Stimulation Enhances Dexterity in Parkinson's Disease: A Randomized Sham‐Controlled Trial

open access: yesMovement Disorders, EarlyView.
Abstract Background Ultrasound‐based neuromodulation, capable of reaching deep brain areas with high precision, represents cutting‐edge technology in non‐invasive brain stimulation and is investigated as a novel treatment for neurological and psychiatric disorders, including Parkinson's disease (PD).

PANAS, oxytocin and resting-state fMRI

open access: yes, 2020
This study will investigate the effect of intranasal oxytocin (OT) administration on the relationship between affect state and resting-state connectivity on the salience network by using resting-state fMRI data in both young and old adult ...

A Hybrid RF Coil for Whole‐Brain Imaging in Non‐Human Primates at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high field MRI (≥ 7 T) offers unprecedented potential for mapping non‐human primate (NHP) brain function. However, complex electromagnetic systems are required to meet the challenges of UHF imaging and the mechanical demands of awake NHP studies.

Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.
