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.

This study identifies a dissociation between short-term and long-term sensorimotor memory in individuals with cerebellar degeneration, revealing the cerebellum's role as a gateway for long-term memory formation.

The paper shows that reducing visual feedback latency from 85ms to 25ms increases implicit sensorimotor learning by 50% and decreases explicit learning, suggesting latency impacts memory reorganization.

The paper investigates the relationship between savings and long-term memory in motor learning, finding a double dissociation between the mechanisms underlying each.

This study investigates whether control of moving and holding is independently affected in stroke patients, finding functional separation between these modes of control despite shared characteristics in resting biases and movement synergies.

This study challenges the forward-model-based theory of motor adaptation by showing that implicit adaptation under mirror-reversed feedback follows a pattern consistent with direct policy learning rather than forward-model-based learning.

The paper investigates how arm holding is controlled by showing that postural fields integrate reach commands, even after corticospinal damage.
