The paper investigates how neural excursions from a low-dimensional manifold structure in brain networks relate to intersubject variation in motor learning.

The study finds that the dominant arm minimizes muscle effort more effectively than the non-dominant arm during vertical arm movements, as indicated by directional asymmetries and reduced negative epochs in muscular activity.

The paper investigates how Purkinje cells in the cerebellum respond during visuomotor learning, finding mixed selectivity between movement and reward signals.

This study shows that cerebellar Purkinje cells use spike synchronization, not firing rates, to signal when to stop saccadic eye movements in marmosets.

The paper investigates how sensory prediction errors and task errors interact in implicit motor learning and finds that task errors alone cannot drive recalibration but modulate it when sensory prediction errors are present.

The paper shows that task space exploration improves adaptation after incompatible virtual surgeries by enabling learning of new muscle synergies.

The paper shows that aligning tasks with ankle joint mechanics reduces muscular effort and improves task performance and perception of ease.

The paper shows express arm responses occur bilaterally in upper-limb muscles during reaching tasks, supporting the involvement of the reticulo-spinal tract.

This study examines how eye-hand coordination during movement corrections depends on task-specific visual and cognitive demands, finding that hand corrections typically precede eye corrections in certain conditions.

This study shows that finger stability during precision grips is primarily due to muscle stiffness rather than feedback control, and external stiffness can enhance force application but may reduce adaptability.

This study investigates the role of the anterior intraparietal cortex in anticipatory force scaling and the size-weight illusion using transcranial magnetic stimulation.

The paper compares neural network models to determine a biologically plausible explanation for how muscle synergies are implemented in the spinal cord, finding that a population model with moderate variation matches experimental data.

The paper shows that different components of motor commands are distributed across two types of cortical projection neurons in mice.

This study investigates how sensory feedback influences the control of skilled finger movement sequences, finding that haptic feedback drives rapid adjustments during execution.

The paper investigates how movement strategies under choice uncertainty reflect risk/reward-seeking tendencies, showing direct reaches are biased by success likelihood while intermediate reaches are biased by reward.

The paper shows that cyclic, condition-independent neural activity in primary motor cortex predicts peak movement speed during both initial and corrective reaching movements in rhesus macaques.

This study investigates how target reward influences feedback control during motor tasks, finding increased feedback gains and changes in movement flexibility based on reward context.

The paper investigates how implicit and explicit learning systems compete during sensorimotor adaptation, showing that shared error signals can lead to competition and reduced learning in one system when the other is enhanced.

This study investigates how temporal perturbations affect sensorimotor adaptation across different movement types and modalities, finding that adaptation is context-independent but modality-specific.

This study investigates theta oscillations in the cerebellum and supplementary motor area during visuomotor adaptation, finding that theta power changes correlate with adaptation performance and connectivity.

The paper compares movement smoothness between physical and motor imagery practice, finding that physical practice leads to smoother movements as indicated by fewer velocity peaks.

This paper introduces a network information theoretic framework to extract muscle synergies, capturing spatial, temporal, and spatiotemporal interactions in reaching movements.

The paper shows that cerebellar connectivity maps in mice vary with locomotor conditions and correlate with individual behavioral features.

This study investigates how motor learning alters preparatory neural activity in monkeys, finding both task-specific and uniform shifts that may support motor memory retention.
