Reproducibility and agreement of pulse wave velocity and augmentation index over repeated assessments using two different devices in adolescents

Clinical Physiology and Functional Imaging, Volume 46, Issue 2, March 2026.
Abstract Objectives We investigated the agreement between pulse wave velocity (PWV) and augmentation index (AIx%) obtained in a controlled fasted condition versus a non‐fasted, uncontrolled, “real‐world” condition. Thereafter, we assessed the reproducibility of PWV and AIx% over three repeated visits under controlled fasted conditions.

Wireless optically pumped magnetometer MEG

NeuroImage
The current magnetoencephalography (MEG) systems, which rely on cables for control and signal transmission, do not fully realize the potential of wearable optically pumped magnetometers (OPM). This study presents a significant advancement in wireless OPM-

Amyloid‐related default mode network hyperconnectivity and longitudinal decline in network distinctiveness in preclinical Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION We investigated stage‐specific alterations in functional connectivity (FC) of the default mode network (DMN) across the Alzheimer's disease (AD) continuum and tested whether early amyloid beta (Aβ)–related changes in within‐DMN FC (DMN‐FCwithin) predicted longitudinal alterations in DMN between‐network connectivity (DMN‐FCbetween).

A thalamocortical pathway for fast rerouting of tactile information to occipital cortex in congenital blindness

Nature Communications, 2019
In congenitally blind people, tactile stimuli can activate the occipital (visual) cortex. Here, the authors show using magnetoencephalography (MEG) that occipital activation can occur within 35 ms following tactile stimulation, suggesting the existence ...

Intranasal Seletracetam in a Patient with Reading Epilepsy: First‐in‐Human Use to Prevent Reflex Seizures

Annals of Neurology, Volume 99, Issue 2, Page 535-539, February 2026.
We report the first human use of intranasal seletracetam (SEL) to prevent reflex seizures. A patient with epilepsy with reading‐induced seizures on levetiracetam (3,000 mg/day) continued to experience reading‐induced focal seizures with preserved consciousness.

Multimodal brain imaging with magnetoencephalography: A method for measuring blood pressure and cardiorespiratory oscillations

Scientific Reports, 2017
Studies with magnetoencephalography (MEG) are still quite rarely combined simultaneously with methods that can provide a metabolic dimension to MEG investigations.

Executive Impairment in Huntington's Disease: Insights From a Systematic Review of the Literature

Brain and Behavior, Volume 16, Issue 2, February 2026.
Executive dysfunction in Huntington's disease follows a selective, stage‐dependent pattern, with early deficits in psychomotor speed, cognitive flexibility, inhibition, and working‐memory updating. Progression is associated with broader impairments in planning and attention.

The Role of MRI in Debunking the Fallacy of “Mild” Traumatic Brain Injury

Journal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 297-309, February 2026.
ABSTRACT Mild traumatic brain injury (mTBI) is a prevalent yet often overlooked public health concern due to the absence of detectable abnormalities on CT or conventional MRI scans. Approximately 18.3%–31.3% of mTBI patients experience persistent symptoms 3–6 months post‐injury, despite normal imaging results, making diagnosis and treatment challenging.

Pharmacological MRI: Utility in Understanding Drug Mechanisms in Psychiatric Disorders

Journal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 346-363, February 2026.
ABSTRACT Pharmacological MRI (pharmaMRI) has emerged as a powerful tool to study how psychoactive drugs affect brain function and to uncover mechanisms of drug action in psychiatric disorders. This review provides an overview of key techniques used in pharmaMRI, including BOLD‐fMRI, arterial spin labeling (ASL), and cerebral blood volume (CBV) mapping,
