The paper investigates small-saccade triggering in rhesus macaques, finding longer reaction times for small saccades and asymmetry in upward vs. downward visually guided saccades.

This study investigates how sub-sensory electrical noise stimulation affects motor performance during visuomotor tasks with varying visual feedback, finding benefits when proprioception is dominant but limited effects when visual feedback is present.

The paper shows that the superior colliculus rapidly transforms target to gaze coding during reactive saccades, with timing determining spatial coding across cell types.

This study investigates how humans monitor their sensorimotor confidence during visuomotor tracking tasks and finds that recent errors have a greater influence on confidence judgments.

The paper investigates how different visuomotor transformations are remembered implicitly, finding that distinct body states are necessary to separate aftereffects.

The paper investigates how explicit control affects error sensitivity during motor adaptation, finding that consistent environments enhance learning when explicit strategies are used.

This study investigates how frontal eye field neurons process multiple saccade plans during sequences, showing concurrent activity for both the current and next saccade.

The paper examines how motor preparation for coordinated movements involving multiple joints affects cortical coupling, finding increased ipsilateral and interhemispheric connectivity with task complexity.

This study shows split-belt walking changes active, but not passive, perception of step length, suggesting motor adaptation alters limb position estimation without affecting sensory input.

The paper investigates neural mechanisms underlying reaction times in smooth pursuit eye movements, finding trial-by-trial correlations between neural activity and behavioral latency.

The paper examines how eye movements during visuomotor adaptation reflect explicit learning, finding that they capture only part of the explicit component, with reaction times correlating with the eye-movement-related part.

The paper shows that action intentions can be predicted from neural signals in both dorsal and ventral visual streams using visual, memory-based, and somato-motor information, even without direct visual input.

This study shows that simultaneous perception of size and weight during object lifting reduces the size-weight illusion below discrimination thresholds, supporting the prediction mismatch theory.

This study shows that climbing fibers in the cerebellum encode expected reward size during a task, suggesting a broader role in associative learning.

The paper investigates neural representations of hand postures during grasping in primates, finding that somatosensory and motor cortex track multi-joint hand configurations differently than arm movements during reaching.

The paper investigates corticospinal excitability changes during movement preparation and finds that preparatory inhibition is a necessary state for planned movements, with different triggering strategies for reaction time and self-paced tasks.

This study shows that motor cortex neuronal populations encode limb movement differently based on environmental context, with M2 influencing this context-dependent encoding.

This study uses TMS to test if PPC regions medial to IPS are involved in online correction of hand and foot movements, finding no effect on movement errors or trajectories.

This study shows that working memory capacity, not dopamine-related genetics, predicts success in reward-based motor learning tasks.

The paper introduces a robotic platform for monitoring sensorimotor signals during natural reaching and grasping tasks in monkeys, demonstrating its use in kinematic studies, neural recordings, and brain-computer interface development.

The paper shows that motor cortex signals for both arms are shared across hemispheres but partitioned in population-level activity to avoid conflicting movements.

This study investigates whether knowledge of Earth's gravity influences eye movements during visual pursuit of parabolic trajectories, finding mixed support for the hypothesis.

This study investigates how kinesthetic motor imagery and contralateral voluntary movements influence the long-latency stretch response (LLR) in upper-limb muscles, finding that voluntary response 'leakage' into the stretched muscle is necessary for LLR facilitation.

The paper examines hippocampal connectivity with sensorimotor cortex during motor tasks, finding bilateral connectivity even without motor learning.

This study examines the impact of visual dynamics cues on learning complex physical interactions, finding that they may hinder generalization when visual context changes.

The paper investigates motor fatigability in healthy adults through repetitive movements, finding that performance decline is linked to reduced surround inhibition in the primary motor cortex.
