Reduced post‐exercise muscle microvascular perfusion with compression is offset by increased muscle oxygen extraction: Assessment by contrast‐enhanced ultrasound
The microvasculature is important for both health and exercise tolerance in a range of populations. However, methodological limitations have meant changes in micro- vascular blood flow are rarely assessed in humans during interventions designed to …
A systematic Review of Studies that Used NIRS to Measure Neural Activation During Emotion Processing in Healthy Individuals
Functional neuroimaging provides an avenue for earlier diagnosis and tailored treatment of psychological disorders characterized by emotional impairment. Near-infrared spectroscopy offers ecological advantages compared to other neuroimaging …
A Functional Near-Infrared Spectroscopy Examination of the Neural Correlates of Cognitive Shifting in Dimensional Change Card Sort Task
This study aims to examine the neural correlates of cognitive shifting during the Dimensional Change Card Sort Task (DCCS) task with functional near-infrared spectroscopy. Altogether 49 children completed the DCCS tasks, and 25 children (Mage = …
Circulating biomarkers of nitric oxide bioactivity and impaired muscle vasoreactivity to exercise in adults with uncomplicated type 1 diabetes
Aims/hypothesis: Early compromised endothelial function challenges the ability of individuals with type 1 diabetes to perform normal physical exercise. The exact mechanisms underlying this vascular limitation remain unknown, but may involve either …
Mitochondrial Capacity and Muscle Endurance in Individuals with Parkinson's Disease
Introduction: Parkinson's disease (PD) is associated with loss of motor control and difficulty exercising. This study measured skeletal muscle mitochondrial capacity and endurance in individuals with and without PD using novel non-invasive methods. …
Thirst perception exacerbates objective mental fatigue
Thirst is represented within the anterior cingulate and insular cortices, and may share some common neuroanatomical structures that are implicated with the regulation of mental fatigue. This novel study investigated whether thirst might modulate the …
The Effect of Spinal Manipulation on the Electrophysiological and Metabolic Properties of the Tibialis Anterior Muscle
There is growing evidence showing that spinal manipulation increases muscle strength in healthy individuals as well as in people with some musculoskeletal and neurological disorders. However, the underlying mechanism by which spinal manipulation …
Investigation of Functional Connectivity During Working Memory Task and Hemispheric Lateralization in Left- and Right- Handers Measured by fNIRS
Working memory is regarded as a cognitive system with limited capacity, which is responsible for saving, manipulating, and remembering online information. The cognitive functions of the brain, such as language, understanding, planning, reasoning, and …
Signal quality index: an algorithm for quantitative assessment of functional near infrared spectroscopy signal quality
We propose the signal quality index (SQI) algorithm as a novel tool for quantitatively assessing the functional near infrared spectroscopy (fNIRS) signal quality in a numeric scale from 1 (very low quality) to 5 (very high quality). The algorithm …
Effect of expiratory loaded breathing during moderate exercise on intercostal muscle oxygenation
Background: In patients with obstructive lung disease, maintaining adequate ventilation during exercise may require greater contraction of the respiratory muscles, which may lead to a compression of muscle capillaries. Furthermore, dynamic …
Rehabilitation improves mitochondrial energetics in progressive multiple sclerosis: The significant role of robot-assisted gait training and of the personalized intensity
Abnormal levels of pyruvate and lactate were reported in multiple sclerosis (MS). We studied the response of markers of mitochondrial function to rehabilitation in relation to type, intensity and endurance performance in severely disabled MS …
An fNIRS examination of executive function in bilingual young children
Aims: The present study aims to examine: (1) the relationship between young children's bilingualism and their performance in the Dimensional Card Change Sort (DCCS) task; and (2) whether prefrontal activation was associated with children's …
Discrimination of Two-Class Motor Imagery in a fNIRS Based Brain Computer Interface
The purpose of this study was to discriminate between left- and right-hand motor imagery tasks. We recorded the brain signals from two participants using a fNIRS system and compared different feature extraction (mean, peak, minimum, skewness and …
A novel gravity-induced blood flow restriction model augments ACC phosphorylation and PGC-1$α$ mRNA in human skeletal muscle following aerobic exercise: A randomized crossover study
This study tested the hypothesis that a novel, gravity-induced blood flow restricted (BFR) aerobic exercise (AE) model will result in greater activation of the AMPK–PGC-1$α$ pathway compared with work rate-matched non-BFR. Thirteen healthy males …
A Systematic Review of Cerebral Functional Near-Infrared Spectroscopy in Chronic Neurological Diseases—Actual Applications and Future Perspectives
Background: The management of people affected by age-related neurological disorders requires the adoption of targeted and cost-effective interventions to cope with chronicity. Therapy adaptation and rehabilitation represent major targets requiring …
Age-related prefrontal cortex activation in associative memory: An fNIRS pilot study
Older adults typically perform more poorly than younger adults in free recall memory tests. This age-related deficit has been linked to decline of brain activation and brain prefrontal lateralization, which may be the result of compensatory …
Deep Cerebellar Transcranial Electrical Stimulation: Hypothesis and Theory for Cannabis Use Disorder
DESIGN AND EVALUATION OF A GUI FOR SIGNAL AND DATA ANALYSIS OF MOBILE FUNCTIONAL NEAR-INFRARED SPECTROSCOPY SYSTEMS A Thesis by
Functional near-infrared spectroscopy (fNIRS) is an emerging neuro-imaging modality that can indicate cortical functionality with good temporal resolution (0.5-1 sec). Unlike fMRI, up to now, there is no standard method and a whole package that can …
Effect of acute nitrite infusion on contractile economy and metabolism in isolated skeletal muscle in situ during hypoxia
Key points: Increased plasma nitrite concentrations may have beneficial effects on skeletal muscle function. The physiological basis explaining these observations has not been clearly defined and it may involve positive effects on muscle contraction …
Effects of acute inspiratory loading during treadmill running on cerebral, locomotor and respiratory muscle oxygenation in women soccer players
Respiratory limitation can be a primary mechanism for exercise cessation in female athletes. This study aimed to assess the effects of inspiratory loading (IL) on intercostal muscles (IM), vastus lateralis (VL) and cerebral (Cox) muscles oxygenation …
