Numerous factors affect motor learning, and its subsequent consolidation into effortlessly retrievable motor memories. Evidence from sleep research suggests a role for sleep in motor learning and motor memory consolidation. Optimal motor performance on a recently learned task is facilitated by sleep-mediated consolidation of motor memories. Yet, sleep independent motor memory consolidation occurs for few tasks and do not appear to hamper performance. Growing evidence, however, is suggestive of a facilitative role for sleep in motor learning. Meanwhile the mechanisms underlying sleep-mediated consolidation of motor memories are not clear, and the possible relevance of hippocampus to motor memory in the context of sleep-state awaits exploration.
