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 …
Effects of Drop-Set and Pyramidal Resistance Training Systems on Microvascular Oxygenation: A Near-Infrared Spectroscopy Approach.
Metabolic stress is a primary mechanism of muscle hypertrophy and is associated with microvascular oxygenation and muscle activation. Considering that drop-set (DS) and crescent pyramid (CP) resistance training systems are recommended to modulate …
Fat Oxidation Kinetics Is Related to Muscle Deoxygenation Kinetics During Exercise
Purpose: The present study aimed to determine whether whole-body fat oxidation and muscle deoxygenation kinetics parameters during exercise were related in individuals with different aerobic fitness levels. Methods: Eleven cyclists [peak oxygen …
Frontal Brain Activity and Subjective Arousal During Emotional Picture Viewing in Nightmare Sufferers
Nightmares are intensely negative dreams that awaken the dreamer. Frequent nightmares are thought to reflect an executive deficit in regulating arousal. Within a diathesis-stress framework, this arousal is specific to negative contexts, though a …
Identification of the cognitive interference effect related to stroop stimulation: Using dynamic causal modeling of effective connectivity in functional near-infrared spectroscopy (fnirs)
Background: The Stroop test is a well-known model to denote the decline in performance under the incongruent condition, which requires selective attention and control of competitive responses. Functional near-infrared spectroscopy can identify …
Thesis The Voice of Primates : Neuro-evolutionary Aspects of Emotions NEURO-EVOLUTIONARY ASPECTS OF EMOTIONS
Rightly emphasized by Pascal Belin “Voices are everywhere”. From music to social conversation, the human voice has indeed the extraordinary power to communicate our everyday emotions. Shaped by millions of years of evolution, the vocal recognition of …
Walking endurance, muscle oxygen extraction, and perceived fatigability after overground locomotor training in incomplete spinal cord injury: A pilot study
Objective: The purpose of this study was to examine the effects of overground locomotor training (OLT) on walking endurance and gastrocnemius oxygen extraction in people with chronic cervical motor-incomplete spinal cord injury (SCI). Design: …
The Impact of Cycling Cadence on Respiratory and Hemodynamic Responses to Exercise
Purpose The physiological consequences of freely chosen cadence during cycling remains poorly understood. We sought to determine the effect of cadence on the respiratory and hemodynamic response to cycling exercise. Methods Eleven cyclists (10 males, …
Plasma asymmetric dimethylarginine concentrations are not related to differences in maximal oxygen uptake in endurance trained and untrained men
New Findings: What is the central question of this study? Is there an association of plasma concentration of asymmetric dimethylarginine, which is related to exercise capacity in patients with cardiovascular diseases, with oxygen delivery and …
Aging effects on prefrontal cortex oxygenation in a posture-cognition dual-task: an fNIRS pilot study
Background: The aging process alters upright posture and locomotion control from an automatically processed to a more cortically controlled one. The present study investigated a postural-cognitive dual-task paradigm in young and older adults using …
Chronic high-dose beetroot juice supplementation improves time trial performance of well-trained cyclists in normoxia and hypoxia
Dietary nitrate (NO 3− ) supplementation via beetroot juice (BR) is known to improve endurance performance in untrained and moderately trained individuals. However, conflicting results exist in well-trained individuals. Evidence suggests that the …
Concurrent anodal transcranial direct-current stimulation and motor task to influence sensorimotor cortex activation
Functional targeting with anodal high-definition transcranial direct current stimulation (HD-atDCS) of involved brain areas during performance of a motor task (online) may facilitate sensorimotor cortex neuroplasticity compared to performing the …
Oxygenation of the Prefrontal Cortex during Memory Interference
Background: Memory interference occurs when information (or memory) to be retrieved is interrupted by competing stimuli. Proactive interference (PI) occurs when previously acquired information interferes with newly acquired information, whereas …
Pre-frontal cortical activity during walking and turning is reliable and differentiates across young, older adults and people with Parkinson's disease
Introduction: Mobility declines with age and further with neurodegenerative disorders, such as Parkinson's disease (PD). Walking and turning ability, in particular, are vital aspects of mobility that deteriorate with age and are further impaired in …
Prefrontal cortical activation measured by fNIRS during walking: effects of age, disease and secondary task
Background: Cognitive processes are required during walking to appropriately respond to environmental and task demands. There are now many studies that have used functional Near-Infrared Spectroscopy (fNIRS) to record brain activation to investigate …
