A Network Centered on the Visual‐Motor Cortex Is Critically Involved in Postural Abnormality in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Postural abnormality (PA) is a key motor symptom in Parkinson's disease (PD) that leads to disability and death. However, the pathophysiology underlying PA is still unknown. Objective The objective of this study was to explore the neural patterns behind PAs and measures toward functional restoration using repetitive transcranial ...

Constipation Is Linked to Neuroinflammation in Early Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Constipation is a risk factor for the onset and accelerated progression of Parkinson's disease (PD), but the mechanisms underlying this association are unknown. Neuroinflammation in PD has been demonstrated in postmortem and neuroimaging studies; however, its relationship with constipation has not been investigated.

Modulation of Non‐Rhythmic Temporal Prediction by Subthalamic Nucleus Deep Brain Stimulation (STN‐DBS) in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Background Accurate temporal prediction, essential for adaptive motor behavior, relies on corticobasal ganglia circuits. In Parkinson's disease (PD), both motor and non‐motor functions are impaired. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) effectively alleviates motor symptoms, but its effects on non‐motor domains, like temporal ...

CEST MRI Processing Pipeline in Pilot Study of Alzheimer's Disease Patients

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a processing pipeline combining neuroimaging analysis tools with CEST postprocessing and utilize it in a pilot study probing differences between cognitively impaired (CI) Alzheimer's disease (AD) patients and cognitively normal (CN) individuals.

Next Generation 7 Tesla Arterial Spin Labeling With Rotated Spiral Acquisition Enables Mesoscale Resolution in 3D Brain Perfusion and Functional MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To achieve high resolution (≤ 1 mm isotropic) whole‐brain perfusion imaging at 7 T with next generation ASL pulse sequence, reconstruction algorithm, and MRI hardware. Methods We capitalized on three major innovations: (1) FLASH‐based pseudo‐Continuous ASL (pCASL) sequence with rotated golden‐angle stack‐of‐spirals (rGA‐SoS) sampling; (
