Coordinate Representations Underlying Arm Movements in Three-Dimensional Space

摘要: Traditionally, researchers interested in the neural control of movement have focused their attention to very simple movements restricted motion at one joint and principal muscles, agonists antagonists, acting about that joint. Given technical conceptual complexities which would need be faced if were attempt study whole-body motion, this is obviously an appropriate beginning. Furthermore, it had been tacitly assumed could extrapolate a relatively straightforward manner insights gained by studying degree freedom understand more complicated multi-degree motions. Reduced extreme, such assumption imply coordination no than simultaneous execution number movements; new problems, other perhaps for synchronization, arise hypothesis valid.
