Summary: A novel distributed-force-feedback-based reflex with online learning (DFRL) is proposed in this study for achieving adaptive motor control and fast postural adaptation. The DFRL integrates force-sensory feedback, reflexes, and learning to cooperate with CPGs in producing adaptive motor commands.

Summary: The existence of mirror neurons in the human brain is largely inferred from indirect non-invasive measurements like functional MRI, based on previous findings in several monkey brain regions. However, the overall usefulness of fMRI adaptation to demonstrate mirror neuron activity in the human brain remains unclear. Therefore, further research is needed to validate the activity of mirror neurons in the human brain.

Summary: Learning from errors is a fundamental mechanism for motor adaptation. Long-term mismatches in motor actions can lead to changes in brain processing that optimize motor learning potential. This study investigates whether short-term mismatches can induce similar effects and suggests that short-term mismatch interventions may be used as a therapeutic strategy to enhance motor learning potential.

Summary: Skilled arm movements require adaptation based on sensory errors, and studies in mice show that forelimb motor adaptation is regulated by the hypothalamic orexin/hypocretin neurons (HONs). By studying goal-oriented mouse-robot interactions, distinct HON signals were found during forelimb movements and motor adaptation. Temporally-delimited optosilencing of these movement-associated HON signals impaired sensory error-based motor adaptation.

Summary: Integrated visual information for motor output is crucial for visually-guided motor control, with the brainstem and midbrain playing a key role in this process. While previous knowledge about brainstem function was mainly based on non-human animal studies, recent fMRI studies in humans have shown activity related to visually-guided motor tasks.

Summary: This study investigated the effects of unilateral cathodal transcranial direct current stimulation (C-tDCS) on static postural stability. The results suggest that the right parietal region contributes to static standing balance through visual information processing, while the left parietal region relies on somatosensory information for static standing balance.

Summary: Vocal flexibility, particularly in speaking and singing, is a key feature of the human species thanks to the neural pathways and coordination in the brain. Two larynx motor areas have been identified in the human brain, with their functional roles in speech motor control still under investigation. The integration of laryngeal and respiratory systems in these areas plays a crucial role in vocalization and may have implications for the evolution of speech.

Summary: The study found that aging may not necessarily lead to a decline in action planning and action adaptation, challenging the notion that healthy aging is associated with a general deficit in motor functioning.

Summary: Conflict adaptation exists not only within the same domain, but also across different domains with shared cognitive control mechanisms. A study used a cross-task adaptive design to explore the relationship between bilingual language control and cognitive control, finding that conflict settings from previous tasks changed neural connectivity levels and influenced the activation of control networks.

Summary: This study focused on two characteristics of human motor control regarding an acquired skill. It found that our movement is corrected based on errors even without the intention to correct them, and our movement outcomes vary even when attempting to perform the same movement repeatedly. The study also investigated the relationship between motor variability and motor adaptation, and found that larger motor variability leads to a greater correction of movement when a large error occurs.

Summary: In this study, the gait imagery-specific networks in ALS patients were assessed using dynamic causal modeling (DCM) and parametric empirical Bayes (PEB) framework. The results showed that UMNp patients had a significant increase in imagery time compared to healthy controls and LMNp patients. During precision gait, the connectivity in UMNp group decreased while the LMNp group showed enhanced bilateral connectivity. The findings highlight the differences in network connectivity patterns in different ALS patient phenotypes.

Summary: This article presents a novel method for reference trajectory adaptation in lower limb rehabilitation exoskeletons during walking. The proposed method utilizes a cost function to restrict the boundaries of the reference trajectory adaptation and has been analytically studied for convergence and optimality. Simulation results demonstrate the effectiveness of the proposed method in enhancing gait stability and spatiotemporal parameters.

Summary: This narrative review aims to establish a framework for understanding age-related changes in neural control of human locomotor adaptation, focusing on reactive feedback and predictive feedforward control driven by sensory feedback during locomotion. The effects of aging on different locomotor adaptation paradigms will be discussed in light of the neural mechanisms underlying locomotion.

Summary: This study proposes a multi-penalized state-space model for analyzing unobserved dynamics, using a data-driven regularization method. Novel algorithms are developed to solve the model, and a cross-validation method is introduced to evaluate regularization parameters. The effectiveness of this method is validated through simulations and real data analysis, enabling a more accurate exploration of cognitive brain functions.
