Dopamine alters motor learning performance in the presence and absence of feedback

This study investigates how dopamine affects motor learning with and without external feedback, finding that dopamine influences performance in both scenarios.

Musical training improves planning and robustness of sequence learning

This study shows that musical training enhances the development of predictive motor control during sequence learning consolidation, making motor memories more robust to interference.

Sounds and Sights in Sequence Learning: Can Accessory Auditory Cues Enhance Motor Task Performance?

This study shows that combining auditory and visual stimuli enhances motor sequence learning compared to visual-only conditions, with informative auditory cues improving learning outcomes.

Time affects a time-consuming, flexible component and a fast, inflexible component of sensorimotor adaptation.

The paper investigates how time affects two distinct components of sensorimotor adaptation: a flexible error-driven component and a less-flexible error-driven component, finding that time alters both.

Intensity-dependent effects of tDCS on motor learning are related to dopamine

This study shows that different intensities of tDCS affect motor learning, and dopamine modulates this effect, with higher intensity improving learning but being reversed by dopamine increase.

Dopamine increases accuracy and lengthens deliberation time in explicit motor skill learning.

This study shows that increasing dopamine availability improves aiming accuracy and extends deliberation time during explicit motor skill learning in humans.

Enhanced neural representation of reach target direction for high reward magnitude but not high target probability.

The paper investigates how reward magnitude and target probability influence sensorimotor processing by decoding movement direction from EEG data, finding that reward magnitude enhances spatial precision of neural representations.

Dopamine alters the effect of brain stimulation on decision-making

This study shows dopamine interacts with tDCS to impair decision accuracy and discriminability in a speed-accuracy trade-off task.

Supplementary motor area contributions to rhythm perception

This study investigates how supplementary motor area (SMA) excitability affects rhythm discrimination using transcranial direct current stimulation (tDCS), finding improved performance with increased SMA excitability.

Acoustic stimulation increases implicit adaptation in sensorimotor adaptation

This study investigates how unpredictable loud acoustic stimulation enhances sensorimotor adaptation by improving initial adaptation and overnight retention.

Task errors drive memories that improve sensorimotor adaptation.

The paper shows that task errors, not sensory prediction errors, drive latent sensorimotor memory and improve adaptation to visuomotor perturbations.

Task errors contribute to implicit remapping in sensorimotor adaptation

The paper investigates how task errors influence implicit remapping in sensorimotor adaptation by manipulating target positions during movement.

Triggering mechanisms for motor actions: A mini meta-analysis and experimental data.

The paper meta-analyzes studies on motor action triggering, finding faster premotor reaction times in trials with sternocleidomastoid muscle activity, and presents experimental data on foreperiod predictability effects.

Cerebellar anodal tDCS increases implicit visuomotor remapping when strategic re-aiming is suppressed

This study shows cerebellar anodal tDCS enhances implicit visuomotor remapping during sensorimotor adaptation, regardless of whether explicit re-aiming is suppressed or allowed.

Estimating the implicit component of visuomotor rotation learning by constraining movement preparation time.

The paper compares two methods to estimate implicit visuomotor rotation learning: constraining movement preparation time and self-reporting aiming directions, finding that preparation time constraints suppress re-aiming without requiring self-reports.

The primary motor cortex is critical for the retention of implicit sensorimotor adaptation

This study shows that the primary motor cortex (M1) is critical for retaining sensorimotor adaptations learned implicitly when explicit strategies are suppressed.
