Impact of two different periodized aerobic training on acute cerebrovascular response and cognitive performance in coronary heart disease patients
The aim of this study was to measure the effects of chronic and acute aerobic exercise at two different intensities on cognitive performance and cerebrovascular response in coronary heart disease (CHD) patients. Thirty‐five CHD patients completed two …
Improvement of classification accuracy of functional near-infrared spectroscopy signals for hand motion and motor imagery using a common spatial pattern algorithm
Objective Classifying motor imagery tasks via functional near-infrared spectroscopy (fNIRS) poses a significant challenge in Brain-Computer Interface (BCI) research due to the high-dimensional nature of the signals. This study aims to address this …
Syntactic development and its interplay with word processing and working memory in preschoolers’ brain: An fNIRS longitudinal study
Understanding how children acquire syntactic structures from a limited set of grammatical rules and use them creatively to convey meaning has been a longstanding interest for scientific communities. Previous studies on syntactic development have …
Deciphering brain activation during wrist movements: comparative fMRI and fNIRS analysis of active, passive, and imagery states
Understanding the complex activation patterns of brain regions during motor tasks is crucial. Integrated functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS) offers advanced insights into how brain activity …
High-intensity interval training with blood-flow restriction enhances sprint and maximal aerobic power in male endurance athletes
High-intensity interval training (HIIT) can improve endurance performance. Purpose: We investigated the concurrent impact of HIIT and blood-flow restriction (BFR) as a novel approach to further enhance maximal aerobic and anaerobic physiology and …
Individual muscle hypertrophy in high-load resistance training with and without blood flow restriction: A near-infrared spectroscopy approach
We aimed to compare individual hypertrophic responses to high-load resistance training (HL-RT) or high-load with blood flow restriction (HL-BFR). Furthermore, we investigated whether greater responsiveness to one of the protocols could be explained …
The Use of Functional Near-Infrared Spectroscopy (fNIRS) for Monitoring Brain Function, Predicting Outcomes, and Evaluating Rehabilitative Interventional Responses in Poststroke Patients with Upper Limb Hemiplegia: A Systematic Review
Functional near-infrared spectroscopy (fNIRS) has been increasingly applied in poststroke research. The accumulated evidence in this area warrants a comprehensive review systematically investigating the utility of fNIRS in poststroke rehabilitation, …
Boys vs men differences in muscular fatigue, muscle and cerebral oxygenation during maximal effort isometric contractions: the effect of muscle blood flow restriction
Purpose To examine whether the children’s superiority, over adults, to resist fatigue during repeated maximal-efforts depends on their often-cited oxidative advantage, attributed to greater muscle blood flow and O2-delivery. We also investigated the …
Lights on music cognition: A systematic and critical review of fNIRS applications and future perspectives
Research investigating the neural processes related to music perception and production constitutes a well-established field within the cognitive neurosciences. While most neuroimaging tools have limitations in studying the complexity of musical …
Increased fatigability and impaired skeletal muscle microvascular reactivity in adults with obstructive sleep apnea: a cross-sectional study
Background Sympathetic nervous system hyperactivity and chronic intermittent nocturnal hypoxia in individuals with obstructive sleep apnea (OSA) predispose them to microvascular impairment, which may contribute to increased daytime muscle fatigue. …
Using mindfulness-based intervention to promote executive function in young children: a multivariable and multiscale sample entropy study
Early childhood marks a pivotal period in the maturation of executive function, the cognitive ability to consciously regulate actions and thoughts. Mindfulness-based interventions have shown promise in bolstering executive function in children. This …
Connecting the dots: Sensory cueing enhances functional connectivity between pre‐motor and supplementary motor areas in Parkinson's disease
People with Parkinson's disease often exhibit improvements in motor tasks when exposed to external sensory cues. While the effects of different types of sensory cues on motor functions in Parkinson's disease have been widely studied, the underlying …
Low frequency oscillations reflect neurovascular coupling and disappear after cerebral death
Spectrum power analysis in the low frequency oscillations (LFO) region of functional near infrared spectroscopy (fNIRS) is a promising method to deliver information about brain activation and therefore might be used for prognostication in patients …
Comparison of LED- and LASER-based fNIRS technologies to record the human peri‑spinal cord neurovascular response
Recently, functional Near-Infrared Spectroscopy (fNIRS) was applied to obtain, non-invasively, the human peri‑spinal Neuro-Vascular Response (NVR) under a non-noxious electrical stimulation of a peripheral nerve. This method allowed the measurements …
Reproducibility and sex differences in muscle oxygenation during brachial artery occlusion in healthy participants
Significance: Near‐infrared spectroscopy (NIRS) measurement is a widely used technique to measure muscle oxygenation. A knowledge of the reproducibility of NIRS measurements is essential for the correct interpretation of data. Aim: Our aim was to …
Impaired muscle oxygenation despite normal pulmonary function in uncomplicated type 2 diabetes
Long-term hyperglycemia in individuals with type 2 diabetes can detrimentally impact pulmonary function and muscle oxygenation. As a result, these factors can impede the body's adaptation to physical exertion. We aimed to evaluate the oxygen pathway …
Tracking the Recovery of a Mild Traumatic Brain Injury Patient utilizing a 60 s Combined Functional Near-Infrared Spectroscopy and Psychomotor Testing Approach A Case Study
