Summary: This study investigated the immediate effects of noise electrical stimulation on proprioceptive senses and grip force control, as well as the associated neural activities in the central nervous system. The results showed that optimal intensity noise stimulation could improve both force and joint proprioceptive senses, and individuals with higher gamma coherence demonstrated better force proprioceptive sense improvement with 30-min noise electrical stimulation. These findings suggest the potential clinical benefits of noise stimulation for individuals with impaired proprioceptive senses and indicate the characteristics of individuals who might benefit from noise stimulation.

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: This study aimed to investigate the influence of visual feedback and executing body side on corticomuscular coherence (CMC). The results showed that the absence of visual feedback decreased CMC peak frequency and amplitude, as well as decreased beta band power in the electroencephalogram. Additionally, CMC was not dependent on the executing hand. Modulation of visual information changed corticomuscular synchronizations and cortical involvement.

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: This study developed a novel delay estimation method, RVC, to detect time delay between coupled neurophysiological signals. The results showed that RVC method was superior in estimating different time delays and had better optimization effect on MSC image compared to the CMCTL method. The RVC-based delay compensation also significantly optimized the MSC of specific regions.

Summary: In this study, the corticomuscular mechanisms underlying blood flow occlusion (BFO) were investigated. The results showed that occlusion of non-exercising musculature suppressed electroencephalographic (EEG) alpha activity in the prefrontal cortex. On the other hand, occlusion of exercising musculature suppressed EEG alpha activity in central and posterior cortical regions and impaired brain-muscle communication and neuromuscular activation.

Summary: In this study, the concept of spatial-temporal CMC (STCMC) is proposed to improve the accuracy of corticomuscular coupling analysis. By combining delay compensation and spatial optimization, STCMC enhances the coherence significantly between brain and muscle signals and produces higher classification accuracy. Furthermore, STCMC provides more detailed brain topographical patterns, emphasizing the different roles between the contralateral and ipsilateral hemisphere.

Summary: This study investigated the spread of decisional effects in a lexical decision task across multiple electrophysiological indexes related to motor-response implementation. The results showed lexicality effects only on indexes of motor planning and execution, with no involvement of other measures. This pattern is discussed in relation to the hypothesis of multiple decisional components exerting different influences across the motor-hierarchy.

Summary: The study revealed that sensory tricks can improve cortical function and reduce corticomuscular connectivity in cervical dystonia patients, ultimately alleviating the dystonic symptoms. Differences in corticocortical and corticomuscular coherence were observed between healthy subjects and different patient subgroups during the execution of sensory tricks.

Summary: This study investigates the transmission speeds of cortical beta rhythms to arm and leg muscles during mild contractions in humans. Two improvements for estimating corticomuscular beta transmission delays are proposed, leading to the discovery that descending corticomuscular beta transmission is only slightly slower than expected from the fastest corticospinal pathways. Simulation results suggest two possible scenarios to explain fast corticomuscular transmission, with implications for our understanding of corticomuscular interactions.

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: Attention deficit hyperactivity disorder (ADHD) is a main cause of school failure in children, and visual processing deficits related to ADHD can be identified through changes in electroencephalography (EEG) characteristics. This study found that children with ADHD showed significant differences in global weighted coherence and longer response times when processing inconsistent visual stimuli. Delta and theta EEG bands were important features for classification in both groups.

Summary: Random noise stimulation technique involves applying various forms of energy to the brain or sensory receptors to enhance sensory, motor, or cognitive functions. Recent studies have shown that transcranial random noise stimulation can increase corticospinal excitability, improve cognitive/motor performance, and produce positive effects at the behavioral and psychological levels. Random noise stimulation has potential uses in treating neurological disorders and further research is needed to discover optimal methods of application.

Summary: This study examined the neuroplastic effects of spinal manipulation with an Activator IV instrument on the bilateral H-reflex amplitude in dancers and non-dancers. The results showed that ten sessions of spinal manipulation did not cause significant changes in the H-reflex amplitude in either group. Furthermore, there was no significant difference in the effects of spinal manipulation between the two groups, despite their different baseline H-reflex amplitudes. Further research is needed to understand the mechanisms involved.

Summary: This report details the use of an OPT-101 photodetector and red light LED to detect DC-PPG signals in the spinal cord and brainstem, as well as the successful transmission of these signals wirelessly. By varying the distance between the photodetector and LED, the wireless system was able to detect all transmitted signals, with decreasing output and wireless potential observed at longer distances. Different arrangements of the device have the potential to detect hemodynamic responses in various animal models and human brain wirelessly.
