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: The human foot sole plays a crucial role in balance and walking, and provides important tactile information about contact. This study examined plantar pressure patterns during various daily activities and found that contact area differed across tasks, but was only moderately correlated with overall force. The center of pressure was often located outside the contact area or in regions experiencing low pressure. Non-negative matrix factorization revealed low-dimensional spatial complexity, which increased during interaction with unstable surfaces. These findings offer insights into optimal sensor placements and spatial pressure variations on the foot sole during natural behaviors.

Summary: The use of haptic technologies is becoming the norm in rehabilitation, medical training, and entertainment, but there is still a lack of research on how humans perceive delayed haptic information. In this study, we use EEG to investigate the neural correlates of haptic delay perception. The results suggest that midfrontal theta oscillation and parietal alpha oscillation play important roles in quantifying the amount of haptic delay and encoding its presence.

Summary: This study investigated whether postural tasks involving light fingertip touch would increase attentional demands, and if so, whether it would be reflected in measures of COP regularity. The results showed that postural steadiness and COP regularity were reduced during touch conditions compared to no-touch conditions, suggesting that actively touching an external surface with the fingertip might generate an externally oriented focus of attention, leading to a more automatic control of posture.

Summary: This study investigates the cortical mechanisms underlying visually guided steps and highlights the role of oscillatory communication in the parieto-frontal and corticomuscular network. The findings suggest that the brain utilizes coherence to flexibly fine-tune inter-regional communication during human stepping, contributing to the precision control of large-scale movements.

Summary: The study investigated the motor network connectivity in adult survivors of polio by analyzing the corticomuscular coherence during a pincer grip task. The results showed significant coherence in low gamma frequency bands in the frontal and parietal regions of polio survivors, suggesting a disease-related functional reorganisation of the cortical motor network, which has implications for other LMN conditions like SMA.

Summary: In this study, an automated labeling method was proposed to address the labeling issue in self-paced brain-computer interfaces, and a pseudo-online evaluation suite was developed to facilitate online BCI research. The experimental results showed that the automated labeling method performed well in handling noisy data, and the online model demonstrated different performance compared to the offline model. These findings take a concrete step towards real-world self-paced BCI systems.

Summary: Intelligent poststroke rehabilitation using electromyographic (EMG) signals and electroencephalographic (EEG) signals has attracted great attention worldwide. This article provides an overview of using EMG and EEG signals in rehabilitation, focusing on the changes after stroke and the technological interventions. The feasibility of motor function rehabilitation with these signals is analyzed, showing that the combination of EEG and EMG signals is more favorable for rehabilitation than using a single signal.

Summary: Strength training induces corticomuscular adaptations leading to enhanced strength by altering agonist and antagonist muscle activations, changing motor control for improved force production stability and accuracy. Results suggest that neurophysiological adaptations are noticeable as soon as 1 week post-training, but central motor adaptations may take longer to be translated into corticomuscular coherence alteration.

Summary: The new dry 256-channel HD-EEG electrode cap overcomes the principal limitations of HD-EEG in terms of preparation complexity, allowing rapid application by non-medically trained individuals, and enabling new use cases for HD-EEG. The dry electrodes make recording with state-of-the-art EEG amplifiers easier, while also demonstrating superior performance and wearing comfort.

Summary: This study compares the impact of different EMG pruning methods on EEG signals and finds that EMG contamination exceeds EEG signals as frequencies increase and distance from the central scalp area increases. Researchers should reevaluate conclusions from high-frequency EEG data and be aware of the limitations of current EEG de-contamination methods.

Summary: Impaired blood pressure recovery with orthostatic hypotension is common in older adults and is associated with low cerebral blood flow. This study found that posture-related reductions in cerebral tissue oxygenation can impact stability upon standing, and a brief sit before standing may improve oxygenation and stability. Older adults with lower tissue oxygenation and greater instability might have an increased risk of future falls.

Summary: The study found that in older adults, the ability to inhibit responses is correlated with performance on a reactive balance test, with individuals who perform well in a cognitive stop signal task also showing better control during balance recovery. This suggests a relationship between cognitive abilities and balance control, indicating that a simple cognitive test could potentially be used clinically to predict an individual's capacity for adapting balance reactions and fall risk. Further studies with larger samples are needed to verify this relationship between stop signal reaction time and leg response during balance recovery.

Summary: The study found that bilingualism does not lead to cognitive advantages in Parkinson's disease patients. Bilingual individuals with PD performed worse on attention/working memory and language measures, possibly due to linguistic information being distributed across multiple languages and lower language proficiency in English.
