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.

Distinct optimization of motor control and learning: Motor learning achieves different motor patterns from overtrained self-paced movements

The paper compares motor control and learning by analyzing how participants adjust movement velocity and duration during self-paced tasks and visuomotor perturbations, finding distinct optimization strategies.

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.

Metabolic mode estimated by breathing reflects long-term motor memory

The paper shows that respiratory exchange ratio (RER) correlates with long-term motor memory retention and that glucose intake improves 24-hour retention.

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.

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.

Influence of switching rule on motor learning

This study shows that motor learning effects are partially transferable between pro- and anti-reaching movements even when movement direction is the same, indicating that rule switching affects learning transfer.
