Across a meta-analysis of 114 datasets and preregistered experiments with 526 participants, we find that sensorimotor adaptation and interlimb transfer are strikingly symmetric across hands. The results suggest a fundamental dissociation: motor control is lateralized to the dominant hemisphere, while motor learning is supported by a symmetric neural architecture.
