Reinforcement Learning Is Impaired in the Sub-acute Post-stroke Period

This study finds that reinforcement learning is impaired in the sub-acute post-stroke period, while error-based learning remains unaffected, suggesting the need for adjusted rehabilitation strategies.

No evidence for motor recovery-related cortical reorganization after stroke using resting-state fMRI

This study finds no evidence of cortical reorganization after stroke using resting-state fMRI despite behavioral recovery.

Symmetric Intralimb Transfer of Skilled Isometric Force Production

The paper shows that motor skills learned with one effector transfer to both proximal and distal effectors, unlike visuomotor adaptation which is asymmetric.

Fatigue induces long lasting detrimental changes in motor skill learning

This study shows that fatigue impairs motor skill learning even when task execution is not affected, suggesting training beyond fatigue may hinder long-term skill acquisition.

Motor Cortex Excitability Reflects the Subjective Value of Reward and Mediates its Effects on Incentive Motivated Performance

The paper investigates how motor cortical excitability reflects subjective reward value and mediates its impact on incentive-driven performance in humans.

Finger recruitment patterns during mirror movements suggest two systems for hand recovery after stroke

The paper analyzes mirror movements in stroke patients to assess contributions from cortical and subcortical pathways to hand recovery.

Recovery of hand function after stroke: separable systems for finger strength and control

This study tracks recovery of hand function after stroke, finding that strength and finger control recover differently, with individuation improving beyond a strength threshold due to CST-dependent mechanisms.
