* 19 10 31 A Consideration of Motor Skill Learning Brain Pathway Shift and Memory Consolidation Keiko HASHIMOTO * In motor skill learning, it is known that extensive practice produces a shift in the brain pathways, and that the existence of memory consolidation, especially, sleep-dependent consolidation, is clearly seen. This paper discussed motor skill learning based on some recent reports on these matters. Both of brain pathway shift and consolidation are not exclusive phenomena in motor skill learning, but they provide some keys to understand the nature of motor skill learning. In addition, it was suggested that declarative memory might have some involvements in motor skill learning processes.
