Summary: This study investigates how action experience shapes the processes of perceiving and anticipating others' actions in infants. The research finds a link between action experience and connectivity patterns, particularly during the anticipation period. The study also highlights the role of visual-motor networks in the link between motor skills and action encoding.

Summary: Research indicates that individuals with autism spectrum disorder exhibit increased force variability and reduced entropy during visuomotor behavior, along with greater brain activation and decreased functional connectivity. Additionally, delayed maturation is observed in the functional connectivity between cerebellar-cortical sensorimotor and nonsensorimotor networks.

Summary: Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental disorder that affects normal brain development. This study examined brain connectivity as a potential biomarker for ASD. The findings showed that children with ASD had increased local connectivity in functional connectivity, but decreased effective connectivity between brain hemispheres. These connectivity abnormalities may serve as biomarkers for ASD.

Summary: EEG coherence analysis is a widely used method to evaluate functional connectivity in brain networks, but the variability in study designs has made comparing findings and understanding underlying brain activity challenging. This paper presents a comprehensive hierarchical EEG coherence analysis structure that includes multiple analysis variables for computing EEG coherences.

Summary: Interpersonal coordination is essential in human interaction, and individual and dyadic differences can lead to different synchronization strategies. Brain mechanisms underlying these strategies show that individuals coordinating via mutual adaptation exhibit more frequent phase-locked activity in transient action-perception related brain networks, suggesting a higher degree of action-perception network coupling.

Summary: This study explored the interaction between auditory and motor systems during the perception and imagination of musical meters, using innovative methods to separate motor and auditory activity while controlling for covert movement. The results demonstrated endogenous brain activity reflecting the imagination of meters, with evidence of motor-to-auditory information flow at the beat rate, supporting the idea of a tightly coupled auditory-motor system in rhythmic processing.

Summary: This study proposed a microstate-based method to explore the differences in microstate dynamics between stroke patients and healthy populations. The results showed that each microstate class was associated with a distinct functional connectivity pattern, and stroke patients exhibited significant differences in most microstate parameters compared to healthy controls. Additionally, there were significant negative correlations between microstate-wise functional connectivity and lower limb motor scores.

Summary: This study investigated whether electrically stimulating frontal and parietal regions using dual-site tACS at mu frequency can modulate motor imagery (MI) performance. The results showed that anti-phase stimulation significantly improved event-related desynchronization (ERD) and classification accuracy during complex tasks, while also decreasing event-related functional connectivity within the frontoparietal network. However, no beneficial effects of anti-phase stimulation were found in the simple task.

Summary: This study aimed to comprehensively and quantitatively investigate the changes in brain activity induced by BCI-FES training in patients with chronic stroke. The results showed that BCI-FES rehabilitation training can significantly improve motor function of patients, improve the functional integration and functional separation of brain networks, and boost compensatory activity in the contralesional hemisphere to a certain extent.

Summary: The main objective of this study was to investigate patterns of brain connectivity during exercise in individuals with low and high tolerance levels. The findings revealed that high-tolerant individuals reported lower perceived activation levels during the initial stages of exercise and higher levels of remembered pleasure upon completion. High-tolerant individuals also exhibited increased connectivity of theta and beta waves in different regions of the brain. These results suggest that low- and high-tolerant individuals may utilize distinct neural networks to process and regulate their psychophysiological state during exercise.

Summary: Brain inflammation and apoptosis contribute to neuronal damage and loss following ischaemic stroke, leading to cognitive and functional disability. H2-relaxin, a hormone with anti-inflammatory and anti-apoptotic effects, shows potential as a therapeutic for stroke. This study investigated the effects of post-stroke administration of H2-relaxin and found that it improved motor function and decreased apoptosis in a dose-dependent manner.

Summary: This study investigates the neural processing and functional connectivity in infants during perception of familiar and novel actions. The results show stronger mu suppression in infants during observation of familiar actions compared to novel actions, indicating a motor-specific neural activity. Additionally, selective motor-visual functional connectivity is found during observation of familiar actions, suggesting the involvement of a functional neural network.

Summary: Motor Imagery (MI) involves imagining motor movements without physical action and has potential applications in rehabilitation and education. The most promising approach for implementing MI is the Brain-Computer Interface (BCI). However, decoding brain responses recorded by scalp electrodes is challenging due to limitations in spatial resolution and non-stationarity. This study proposes a Convolutional Neural Network-based framework to distinguish between MI tasks and identify subjects with poor motor performance at the early stages of BCI training. The proposed method achieves an average accuracy enhancement of 10% compared to the baseline approach, reducing the number of subjects with poor skill from 40% to 20%.

Summary: The study investigated functional connectivity in pediatric arterial ischemic stroke patients, finding that patients with hemiparesis had weaker interhemispheric connectivity, while those with good clinical outcome had higher interhemispheric connectivity strength, which was correlated with better motor outcome.

Summary: This study compared the relationship between index scores and factor analysis results in children with autism and typically developing children in the WISC test. The results showed less unique correlations between index scores and factor analysis results in children with autism, especially in working memory. Therefore, the index scores in the WISC test do not have the desired statistical independence in autistic samples.

Summary: We used a multi-trait, multi-method approach to examine method-associated bias in an ASD sample. The results showed that rater-based scores had a higher methodology bias (57% of score variance explained by method), while performance-based scores had a weaker methodology bias (22%). This confirms concerns about using rater measures in ASD.
