Summary: This study examined the effect of reduced-dimensionality ICA in cleaning EEG data and found that PCA-based rdICA had a significant impact on the mean amplitude of early sensory components under certain conditions, but the impact on other aspects was inconsistent between datasets.

Summary: This study examined intersubject variation in human balance, finding that these differences may arise from variances in central sensorimotor processing. Similar sensorimotor feedback mechanisms were found to be used for sagittal and frontal balance. Sensory weight and integral gain exhibited the highest correlations between planes of motion.

Summary: This study aimed to determine the contributions of two postural balance mechanisms in postures with different areas of the base of support. The results showed that the contribution of M1 decreased with decreased base of support. In the mediolateral direction, the contribution of M2 was significant in certain postures, particularly in the most challenging unipedal posture where it accounted for nearly 90%.

Summary: This study examined the cortical response to sensory and mechanical perturbations in older adults while standing and investigated the relationship between cortical activation and postural control. The results showed that older adults had significantly higher relative beta power at cortical areas related to postural control under sensory and mechanical perturbations. Additionally, as task difficulty increased, young adults had increased relative beta band power while older adults demonstrated decreased relative beta power.

Summary: This study aims to analyze the changes in cortical and muscle connections in healthy subjects during different standing balance tasks. The results show significant changes in the topology of both EEG brain networks and muscle networks as the task difficulty increases. The connection analysis of muscle networks reveals that antagonistic muscle pairs play a major role in the task. The analysis of EEG brain networks based on graph theory shows a significant increase in clustering coefficient and a significant decrease in characteristic path length with increasing task difficulty. It is also found that cortex-to-muscle connections increase with task difficulty and are significantly stronger than muscle-to-cortex connections.

Summary: This study examines the learning process of lower limb control on a hoverboard, specifically focusing on the balance and control strategies adopted by first-time users. The results indicate that these users learn to maintain their balance and control the hoverboard using an ankle strategy, which remains robust despite changes in muscle group activation patterns.

Summary: This review examines the impact of hypoxia on standing balance control, revealing that hypoxia, especially hypobaric, impairs standing balance. This impairment may be due to alterations in the processing and integration of sensorimotor signals, affecting visual, vestibular, and proprioceptive pathways, as well as motor commands for postural adjustments. Further research is needed to identify sensorimotor factors influencing balance control in hypoxic conditions.

Summary: In this study, young tennis players underwent pre- and post-competition testing after a simulated tennis match. The results suggest that an 80-minute match is insufficient to elicit significant changes in postural control and muscle characteristics in these players. Physiological responses triggered by match-play were closer to those seen after moderate activity.

Summary: This study found that performing standing reaching exercises to the nonparetic side on an inclined surface can improve lateral weight-shifting capacity and gait ability in participants in the early poststroke phase.

Summary: The evidence suggests that individuals with psychopathy have difficulty adjusting their behavior according to environmental demands and display altered performance monitoring. Studies have shown contradictory results in electrophysiological markers of error monitoring for this population, and it is hypothesized that different dimensions of psychopathy may influence these outcomes. Individuals with impulsive antisocial features tend to have abnormal ERN responses compared to those with interpersonal-affective features.

Summary: This article investigates the reason why horses tend to stand with vertical legs and provides an explanation through modeling and stability testing. The research finds that a vertical or slightly splayed-out leg posture is more stable, while a canted-in posture requires more neuromuscular effort to maintain balance.

Summary: This study examined the emotional components of event-related potentials in individuals with contamination OCD and revealed that they exhibited larger amplitudes in response to contaminated pictures compared to neutral pictures. These findings have implications for developing targeted and effective treatments for contamination OCD.

Summary: Through a systematic search and analysis of relevant literature, it was found that there is a relationship between psychopathy traits and CNV amplitude. Larger tCNV amplitudes were found in participants with higher psychopathy traits. These findings contribute to a better understanding of the construct of psychopathy and differences in adaptive adjustment patterns.

Summary: This study investigated the cortical mechanisms associated with improvement of postural balance using error amplification (EA). The results showed that EA altered postural strategies and improved stability. This study provides supporting neural correlates for the use of virtual reality with EA during balance training.

Summary: Long-term physical and mental exercise has positive effects on executive functions, possibly through more efficient early attentional processing, according to the study. Practicing both physical and mental exercise together showed better performance in executing attention switching tasks than solely engaging in physical exercise.
