Alterations of resting-state EEG microstates have been associated with various neurological disorders and behavioral states. Interestingly, age-related differences in microstate organization also reported, it has suggested that activity may predict cognitive capacities healthy individuals across the lifespan. In this exploratory study, we performed a analysis brain tested allocentric spatial working memory performance adult individuals: twenty 25-30-year-olds twenty-five 64-75-year-olds. We...
During normal aging resting-state brain activity changes and working memory performance declines as compared to young adulthood. Interestingly, previous studies reported that different electroencephalographic (EEG) measures of may correlate with at ages. Here, we recorded EEG tested allocentric spatial in healthy (20-30 years) older (65-75 adults. We adapted standard methods record mobile participants a non-shielded environment, both eyes closed open conditions. Our study revealed some...
Abstract Contextual interference (CI)—the practice of tasks in a random rather than blocked order—is known to impair immediate performance while enhancing long-term learning and transfer. In simple aiming tasks, CI has been shown improve movement accuracy. However, whether these greater improvements extend unpracticed parameters, such as novel distances or the contralateral hand—a relationship informed by schema theory—remains unexplored. Additionally, non-sequential affect processes that...

However, no performing an intense complete with adequate level of performance. The aim this study was to assess subjective, behavioral and brain activity responses on until failure. Methods In pre-registered, randomized, within-participant design experiment, 29 physically active participants completed failure after running at 90%...

ABSTRACT Introduction The relationship between cognitive tasks and physical performance has garnered significant attention, with evidence suggesting that effort before exercise may impair performance. However, recent findings challenge the robustness of this effect, necessitating a reassessment mechanisms linking load to This study introduces novel approach address methodological limitations, emphasizing individualized task difficulty duration. Using techniques such as Temporal Experience...

Background: The current sports context appears to place adolescent athletes at risk for developing disordered eating behaviors, particularly in lean such as synchronized swimming. However, an athlete’s behavior changes over the course of a season and is influenced by various factors (e.g., pressures related weight appearance, body dissatisfaction, self-esteem), well stress levels. To date, only few studies have examined these variations or explored effects on during season, but understanding...
Abstract The conflict monitoring model predicting higher anterior cingulate cortex (ACC) neuronal activity on incongruent trials has been recently challenged by a longer in characterized RTs. To clarify this issue, brain dynamics were explored through event-related-potential (ERP) recordings during Stroop task. We assessed differences between experimental conditions combining complementary methods sensitive to the temporality of events including microstate, TANOVA and source localization...
Abstract Associative learning abilities vary considerably among individuals, with attentional processes suggested to play a role in these variations. However, the relationship between and individual differences associative remains unclear, whether variations reflect event-related potentials (ERPs) is unknown. This study aimed investigate by recording electrocortical activity of 38 young adults (18–32 years) during an task. Learning performance was assessed using signal detection index d’ ....
Significant progress has been made with regard to the quantitative integration of geophysical and hydrological data at local scale for purpose improving predictions groundwater flow solute transport. However, extending corresponding approaches regional still represents one major challenges in domain hydrogeophysics. To address this problem, we have developed a regional-scale methodology based on two-step Bayesian sequential simulation approach. Our objective is generate high-resolution...
We critically examine the performance of sequential geostatistical resampling (SGR) as a model proposal mechanism for Bayesian Markov-chain-Monte-Carlo (MCMC) solutions to near-surface geophysical inverse problems. Focusing on series simple yet realistic synthetic crosshole georadar tomographic examples characterized by different numbers data, levels data error and degrees parameter spatial correlation, we investigate efficiency three strategies with regard their ability generate...
Abstract Inhibitory control (IC), the ability to suppress inappropriate actions, can be improved by regularly facing complex and dynamic situations requiring flexible behaviors, such as in context of intensive sport practice. However, researchers have not clearly determined whether how this improvement IC transfers ecological nonecological computer-based tasks. We explored spatiotemporal dynamics changes brain activity three groups athletes performing sport-nonspecific sport-specific Go/NoGo...
Abstract Contextual interference (CI) enhances learning by practicing motor tasks in a random order rather than blocked order. One hypothesis suggests that the benefits arise from enhanced early perceptual/attentional processes, while another posits better is due to highly activated mnemonic processes. We propose harness high-density electroencephalography multi-scale analysis approach, including topographic analyses, source estimations, and functional connectivity, examine intertwined...
ABSTRACT Contextual interference (CI) enhances motor learning by practicing skill variations in a random rather than blocked order. It has been demonstrated that performing aiming distances order increased electrophysiological (EEG) markers of perceptual, attentional, and working memory processes. However, only the effect CI on these before training was assessed, without evaluating whether they would decrease with participants trained under compared to condition, indicating enhanced neural...

Abstract Interindividual variations in the ability to perform visuospatial mental transformations have been investigated extensively, particular through rotation tasks. However, impact of early visual processes on performance has largely ignored. To clarify this issue, we explored time‐course processing (from 0 450 ms poststimulus) using event‐related potentials topographic analyses. The main findings demonstrated a significant link between attentional and accuracy scores occurring more than...

Williams (WS) and Down (DS) syndromes are neurodevelopmental disorders with distinct genetic origins different spatial memory profiles. In real-world tasks, where information derived from all sensory modalities is available, individuals DS demonstrate low-resolution learning capacities consistent their mental age, whereas WS severely impaired. However, because associated severe visuo-constructive processing deficits, it unclear whether impairment due to abnormal visual or reflects an...
Higher cardiorespiratory fitness is associated with an increased ability to perform sustained attention tasks and detect rare unpredictable signals over prolonged periods. The electrocortical dynamics underlying this relationship were mainly investigated after visual stimulus onset in tasks. Prestimulus activity supporting differences performance according the level of have yet be examined. Consequently, study aimed investigate EEG microstates 2 seconds before 65 healthy individuals aged...
Human learning is an active and complex process. However, the brain mechanisms underlying human skill effect of on communication between regions, at different frequency bands, are still largely unknown. Here, we tracked changes in large-scale electrophysiological networks over a 6-week training period during which participants practiced series motor sequences 30 home sessions. Our findings showed that become more flexible with all bands from theta to gamma ranges. We found consistent...
