Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Acute exercise‐induced improvements in cognition: Role of cerebral blood flow and metabolism

Experimental Physiology, EarlyView.
Abstract Physical activity is widely recognized for its ability to promote brain health, with acute exercise transiently enhancing cognition and long‐term training attenuating cognitive decline. However, the mechanisms underlying these benefits remain incompletely understood.

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Analyzing the resting state functional connectivity in the human language system using near infrared spectroscopy

Frontiers in Human Neuroscience, 2014
We have evaluated the use of phase synchronization to identify resting state functional connectivity (RSFC) in the language system in infants using functional near infrared spectroscopy (fNIRS).

Functional Near-Infrared Spectroscopy (fNIRS): Principles and Neuroscientific Applications

, 2012
fNIRS is a device designed to detect changes in the concentration of oxygenated (oxyHb) and deoxygenated (deoxyHb) haemoglobin molecules in the blood, a method commonly used to assess cerebral activity. Over the last decade, functional near-infrared spectroscopy (fNIRS) has widely extended its applications due to its capacity to quantify oxygenation in

MRI Goes Mobile: Assessing the Reliability and Repeatability of a Mobile vs. Stationary 1.5 T MRI for Functional Neuroscience Studies

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
We present a technical feasibility study validating two mobile 1.5 T MRI scanners against a stationary system using a five‐subject test‐retest protocol (N = 50 datasets). Following relocation, hardware performance remained stable, with no systematic bias in B0 homogeneity or B1+ maps.

rTMS Over Dorsolateral Prefrontal Cortex Augments Dual‐Task Training for Mobility, Balance and Cognition in Sub‐Acute Stroke: A Randomized Controlled Trial

Physiotherapy Research International, Volume 31, Issue 3, July 2026.
ABSTRACT Objective To evaluate the effects of adding repetitive transcranial magnetic stimulation (rTMS) to dorsolateral prefrontal cortex (DLPFC) with dual‐task (DT) exercise on DT mobility, balance and cognitive performance in individuals with sub‐acute stroke. Methods Thirty sub‐acute stroke patients [age, mean (SD) = 59.2 (7.9) years] were randomly

Validation of the fNIRS Pioneer™, a Portable, Durable, Rugged functional Near-Infrared Spectroscopy (fNIRS) Device

Proceedings of the 12th International Joint Conference on Biomedical Engineering Systems and Technologies, 2019
Assessing cognitive workload using functional near-infrared spectroscopy (fNIRS) in labs is well established. However, fNIRS sensors useful during normal activities in real-world environments are only recently emerging. We validated a small, portable fNIRS sensor (the fNIRS Pioneer TM) against a larger sensor with coverage of a larger cortical area ...
