Heart rate deceleration reflects expectation violation during reaching

This study shows that heart rate deceleration during movement is linked to expectation violations rather than movement errors themselves.

Loud acoustic stimulation reveals an online reticulospinal contribution to long-latency reflexes in humans

This study uses loud acoustic stimulation to demonstrate an online reticulospinal contribution to long-latency reflexes in humans, showing facilitation of the reflex but not the short-latency reflex.

Tonic feedback motor commands predict visuomotor learning

The paper shows that the amplitude of feedback responses during a holding period predicts the magnitude of learning responses in visuomotor tasks.

Fast corrective responses in redundant motor control are shaped by intrinsic constraints of movement patterns

This study shows that fast corrective responses in redundant motor control are shaped by intrinsic coordination constraints rather than flexible re-optimization.

Sensorimotor adaptation to altered postural dynamics implemented via closed-loop neuromuscular electrical stimulation

This study uses closed-loop neuromuscular electrical stimulation to alter postural dynamics and shows that humans adapt systematically to these changes during quiet standing.

Adaptation to transient and local electrical muscle stimulation elicits persistent and global changes in walking kinematics

The paper shows that adaptation to electrical muscle stimulation during walking leads to persistent kinematic changes beyond the perturbation.

Successive failure triggered by motor exploration in a reinforcement-based reaching task

This study examines whether successive failures occur above chance levels during a motor learning task and how they relate to learning outcomes.

Shifts in neural tuning systematically alter sensorimotor learning ability

This study shows that neural tuning shifts during sensorimotor learning alter learning ability in a spatial pattern predicted by computational models.

Divisively normalized neuronal processing of uncertain visual feedback for visuomotor learning

The paper proposes a divisive normalization mechanism to explain how the motor system processes uncertain visual feedback during visuomotor learning.

Implicit motor adaptation patterns in a redundant motor task manipulating a stick with both hands

The paper investigates how the motor system adapts to visual perturbations in a redundant motor task involving a virtual stick manipulated with both hands, revealing that baseline relationships guide implicit adaptation.

Looking for a sign forecasting failure in actions: reaching errors triggered by a slowdown of movement and specific brain activity in preceding trials

The paper identifies behavioral and neural signs preceding movement failure in a reaching task, showing that reduced movement velocity and specific EEG activity occur before failures.

Divisively normalized integration of multisensory error information develops motor memories specific to vision and proprioception

The paper investigates how visual and proprioceptive signals are integrated during motor adaptation and finds that divisive normalization explains movement corrections, with separate motor memories formed for each modality.
