Physical exercise has beneficial effects on neurocognitive function, including hippocampus-dependent episodic memory. Exercise intensity level can be assessed according to whether it induces a stress response; the most effective for improving hippocampal function remains unclear. Our prior work using special treadmill running model in animals shown that stress-free mild increases neuronal activity and promotes adult neurogenesis dentate gyrus (DG) of hippocampus, spatial memory performance....
Increasing evidence suggests that regular moderate exercise increases neurogenesis in the dentate gyrus (DG) of hippocampus and improves memory functions both humans animals. The DG is known to play a role pattern separation, which ability discriminate among similar experiences, fundamental component episodic memory. While long-term voluntary there little alterations function after an acute session. Our previous studies showing exercise-enhanced activation rats, prefrontal executive humans,...
Running, compared to pedaling is a whole-body locomotive movement that may confer more mental health via strongly stimulating brains, although running impacts on but their underlying brain mechanisms have yet be determined; since almost the mechanistic studies been done with pedaling. We thus aimed at determining acute effect of single bout moderate-intensity, most popular condition, mood and executive function as well neural substrates in prefrontal cortex (PFC). Twenty-six healthy...
Abstract A physically active lifestyle has beneficial effects on hippocampal memory function. potential mechanism for this effect is exercise-enhanced plasticity, particularly in the dentate gyrus (DG). Within formation, DG plays a crucial role pattern separation, which ability to discriminate among similar experiences. Computational models propose theoretical hypothesis that enhanced DG-mediated separation leads “memory flexibility”–a selective improvement overcome moderate levels of...
Although it has been traditionally thought that decreasing SpO2 with ascent to high altitudes not only induces acute mountain sickness but also can decrease executive function, the relationship between decreased levels and hypoxia-induced lowered function is still unclear. Here we aimed clarify whether was associated arterial oxygen desaturation, using 21 participants performing color–word Stroop task under normoxic three hypoxic conditions (FIO2 = 0.165, 0.135, 0.105; corresponding of 2000,...
Virtual reality (VR) exergaming is a new intervention strategy to help humans engage in physical activity enhance mood. VR may improve both mood and executive function by acting on the prefrontal cortex, expanding potential benefits. However, impact of has not been fully investigated, associated strategies have yet established.This study aims investigate effects 10 minutes function.A total 12 participants played exergame "FitXR" under 3 conditions: (1) condition (ie, exercise with...
Hearing a groove rhythm (GR), which creates the sensation of wanting to move music, can also create feelings pleasure and arousal in people, it may enhance cognitive performance, as does exercise, by stimulating prefrontal cortex. Here, we examined hypothesis that GR enhances executive function (EF) acting on left dorsolateral cortex (l-DLPFC) while considering individual differences psychological responses. Fifty-one participants underwent two conditions: 3 min listening or white-noise...
Although it has been hypothesized that moderate to vigorous exercise immediately modulates cognition via ascending arousal system activation, such activation during very-light light remained uncertain. Here, we aimed uncover the exact intensity necessary for using pupillometry. The pupil diameter, psychological arousal, and ventilation graded of 26 young males were analyzed based on %[Formula: see text]. Pupils dilated with compared rest, stabilized, then drastically increased again above....
Cognitive fatigue, a transient cognitive decline stemming from extended mental and physical activity, is well established in conventional contexts. However, its manifestation self-awareness during digital pursuits, as an integrated style of notably electronic sports (esports), remain underexplored. Here we show that, using virtual football representative model for esports, prolonged esports cause fatigue with pupil constriction, independent subjective across player expertise. Casual hardcore...
ABSTRACT Purpose Higher aerobic fitness, a physiological marker of habitual physical activity, is likely to predict higher executive function based on the prefrontal cortex (PFC), according current cross-sectional studies. The exact biological link between brain and brawn remains unclear, but dopaminergic system, which acts as driving force for activity exercise, can be hypothesized connect missing above. Recently, spontaneous eye blink rate (sEBR) was proposed has been used potential,...
Abstract The effect of the menstrual cycle on fine motor skills is unclear. This study determined whether affected and related neural activities. Nineteen women with regular cycles were tested for using two types tasks: grooved pegboard task (GPT), which evaluates control high freedom movements, force modulation (FMT), more complex low movements. We also assessed primary cortex intracortical circuits sensorimotor integration paired-pulse transcranial magnetic stimulation to reveal why...
Abstract We previously found that a 10-min bout of moderate-intensity exercise (50% maximal oxygen uptake) under normobaric and hypoxic conditions (fraction inspired [ $${{\text{F}}_\text{IO}}_{_{2}}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mrow><mml:msub><mml:mtext>F</mml:mtext><mml:mtext>IO</mml:mtext></mml:msub></mml:mrow><mml:msub><mml:mrow/><mml:mn>2</mml:mn></mml:msub></mml:msub></mml:math> ] = 0.135) reduced executive performance neural activity in the...
Abstract Transcranial random noise stimulation (tRNS) of the primary sensory or motor cortex can improve sensorimotor functions by enhancing circuit excitability and processing fidelity. However, tRNS is reported to have little effect on higher brain functions, such as response inhibition when applied associated supramodal regions. These discrepancies suggest differential effects cortex, although this has not been directly demonstrated. This study examined regions somatosensory auditory...
Abstract Purpose The effects foam rolling (FR) intervention on lactate clearance and the impaired executive function associated with fatigue after high-intensity exercise remain unclear. This study examined whether FR is an effective tool for recovery. Methods Eighteen healthy adults (10 males, 8 females; 21.8±1.7 years) without consistent habits participated. participants performed exercises using ergometer a progressive load. Post-exercise was compared control condition. Measurements...
Abstract Although virtual reality (VR) exercise has attracted attention as a factor in habituation due to its mood-enhancing effects, impact on brain function remains unclear. This study, involving 23 healthy university students, used functional magnetic resonance imaging (fMRI) explore how VR affects working memory, key executive function, and underlying neural mechanisms. Our findings indicate that 10-min session improved mood (arousal vitality level) memory task performance (3-back task)...
Introduction Repetitive somatosensory stimulation (RSS) is a conventional approach to modulate the neural states of both primary cortex (S1) and motor (M1). However, impact RSS on skill acquisition retention in sensorimotor adaptation remains debated. This study aimed investigate whether whole-hand water flow (WF), unique RSS-induced M1 disinhibition, influences by examining hypothesis that WF leads disinhibition; thereby, enhancing memory retention. Methods Sixty-eight young healthy...
