Summary: During upper-limb casting, disused motor regions showed increased connectivity to the cingulo-opercular network, primarily mediated by large, spontaneous activity pulses. This led to a standby mode characterized by spontaneous activity pulses in the disused motor circuits.

Summary: This paper explores a neural control architecture that is both biologically plausible and capable of autonomous learning. It uses feedback controllers that learn to achieve a desired state by selecting the errors that drive them, employing a family of differential Hebbian learning rules. The architecture can control systems with monotonically or non-monotonically changing error responses through reinforcement learning. The use of feedback control simplifies the learning problem and allows for learning of more complex actions.

Summary: This study aimed to investigate the learning-relative hemodynamic modulation of cortical plasticity induced by long-term motor training. The results showed that cortical hemodynamic activations exhibited an expansion-renormalization trend during continuous motor training, and the enhancement of functional connectivity may be maintained after amplitude renormalization. TMS findings suggested neural facilitations on the descending motor pathway after certain level of learning stages, and the learning could transfer to enhance performance in similar tasks.

Summary: The study found that action video game players had higher performance scores, stronger SICI, and higher MEP amplitudes. There were differences in the relation between reaction time and corticospinal excitability between players and controls, but no differences were found in motor map topography and IO curves. Action video game players demonstrated an increased efficiency in motor cortical inhibitory and excitatory neural networks.

Summary: The study found that short-duration stimulation applied to the cerebellum enhanced movements performed simultaneously with stimulation, while M1 stimulation did not improve adaptation. This suggests that the coupling of cerebellar stimulation and movement plays a crucial role in facilitating enhanced learning in the stimulated context.

Summary: This study examined the activation patterns and coactivation changes in different muscles of older and young participants before and after bed rest. The results showed that older individuals had higher muscle discharge rates in the gastrocnemius compared to the young, regardless of the contraction level. However, the differences were less consistent in the tibialis anterior and soleus muscles. Individual adaptations to aging or bed rest also influenced the results.

Summary: Chandelier cells (ChCs), a type of inhibitory interneurons, establish cortical microcircuits to organize neural coding through selective synaptic plasticity. They contribute to organized motor control by enhancing population coding of direction-tuned premotor neurons, with tuning refined through suppression of irrelevant activity. ChCs mediate learning by establishing inhibitory circuit motifs over individual pyramidal neurons and redistributing inhibitory weights during learning, allowing for efficient cortical computation.

Summary: This study aims to bridge the inherent features of cerebellar motor control and current robotic challenges by implementing a cerebellar-like spiking neural network (SNN) controller that is adaptive, compliant, and robust to variable sensorimotor delays. By replicating the cerebellar mechanisms and allowing motor learning and adaptation, this controller addresses the incompatibility between HRI robots' characteristics and traditional control solutions, as well as the challenge of compliant control in the presence of variable sensorimotor delays.

Summary: Most rehabilitation interventions post-SCI target sublesional spinal networks, but mammalian locomotion involves more than just that. Recovery of cortical control is essential for voluntary movement and gait modulation. Neurostimulation delivered in phase coherence with ongoing locomotion immediately alleviated primary deficits in rats with incomplete SCI.

Summary: Imaging studies have shown that the contralesional cortices are involved in recovery after motor stroke. Analyzing cortical thickness can capture changes in cortical anatomy that are related to recovery and treatment gains. This study investigates whether cortical thickness obtained in the acute phase after stroke can explain outcome variability. The results suggest that the baseline cortical anatomy of selected contralesional cortices can explain outcome variability after severe stroke, contributing to the concept of structural brain reserve for promoting recovery.

Summary: This article reviews the current state of portable/wearable EMG devices for assessment of bruxism. The results show that ultra-miniaturized wearable EMG devices with performance equivalent to conventional devices have been developed and used during sleep and in the daytime, with a high level of diagnostic accuracy for sleep bruxism. However, a definite cut-off value for awake bruxism has not been established.

Summary: Enzyme parameters are crucial for understanding, modeling, and engineering cells. Experimental measurements only cover a small portion of enzyme-compound pairs, and even less in non-model organisms. Artificial intelligence techniques have accelerated the exploration of enzyme properties by predicting them in a high-throughput manner. GotEnzymes is a comprehensive database that provides predicted enzyme parameters using AI approaches, allowing for interactive web exploration and programmatic access.

Summary: This study evaluated the hormonal, immune, and oxidative stress responses in healthy adults following low-load blood-flow restricted resistance exercise (LL-BFRRE) and conventional free-flow resistance exercise (FFRE). The results showed that LL-BFRRE induced higher hormone and immune responses compared to FFRE, and had attenuated oxidative stress responses compared to HL-FFRE.

Summary: In this study, the effects of motor practice on motor performance, accuracy and variability in preadolescent children were investigated. The study also examined changes in corticomuscular coherence following motor practice. Participants performed wrist flexions with specific movement endpoints or force levels. Results showed that position control practice led to greater improvements in movement accuracy compared to force control practice or resting control. There were no significant changes in force task performance or corticomuscular coherence. These findings suggest that preadolescent children improve position control following dynamic accuracy motor practice, but not force control.
